G
reenfield Tap and Die (GTD) has been
supplying the highest quality taps, dies, and
gages to industry for more than 130 years. From
p
remium raw materials, through a stringent
ISO-certified production process, to carefully
inspected, packaged, and shipped tools, GTD
has consistently delivered quality products and
services to you, our customer.
A
lways committed to innovation, GTD continues
to focus on developing products that enable
you to achieve better production at lower costs.
We invented the GUN® tap, which
dramatically improved chip removal for
through hole tapping.
Now, we have introduced new solid
carbide taps for steel (pages 4-6) that offer
increased production rates and longer
tap life, marking the start of a new era
in threading.
We have also developed a line of helical
carbide flute thread mills (pages 53-54)
that feature PVD TiN coating standard.
And, with the installation of GTD’s new
Balzers coating system, we can quickly
provide proprietary, high-performance
coatings within the quality control
specifications of the tool’s manufacturer.
Whether you need off-the-shelf production taps,
a custom solution designed for your toughest
tapping job
,
or premium-quality TiN-coated
thread plug gages, rely on Greenfield Tap and
Die to provide the quality you need, with the
consistency and innovation you deserve.

Modern metalcutting operations involve high
e
nergy, high spindle or cutter speeds, and high
temperatures and cutting forces. Hot, flying
chips may be projected from the workpiece during
metalcutting. Although advanced cutting tool
m
aterials are designed and manufactured to
withstand the high cutting forces and temperatures
that normally occur in these operations, they are
susceptible to fragmenting in service, particularly
if they are subjected to over-stress, severe impact
or otherwise abused. Therefore, precautions
should be taken to adequately protect workers,
observers and equipment against hot, flying chips,
fragmented cutting tools, broken workpieces or
other similar projectiles. Machines should be fully
guarded and personal protective equipment should
be used at all times.
When grinding advanced cutting tool materials, a
suitable means for collection and disposal of dust,
mist or sludge should be provided. Overexposure
to dust or mist containing metallic particles can
be hazardous to health particularly if exposure
continues over an extended period of time and
may cause eye, skin and mucous membrane
irritation and temporary or permanent respiratory
disease. Certain existing pulmonary and skin
conditions may be aggravated by exposure to
dust or mist. Adequate ventilation, respiratory
protection and eye protection should be provided
when grinding and workers should avoid breathing
of and prolonged skin contact with dust or mist.
General Industry Safety and Health Regulations,
P
art 1910. U.S. Department of Labor, published
in Title 29 of the Code of Federal Regulations
should be consulted. Obtain from Greenfield
Tap & Die and read the applicable Material
S
afety Data Sheet before grinding.
Cutting tools are only one part of the worker-
machine-tool system. Many variables exist in
machining operations, including the metal removal
rate; the workpiece size, shape, strength and
rigidity; the chucking and fixturing; the load
carrying capability of centers; the cutter and
spindle speed and tor
que limitations; the holder
and boring bar overhang; the available power;
and the condition of the tooling and the machine.
A safe metalcutting operation must take all of
these variables, and others, into consideration.
Greenfield Tap & Die has no control over the end
use of its products or the environment into which
those products are placed. Greenfield Tap & Die
urges that its customers adhere to the recommended
standards of use of their metalcutting machines
and tools, and that they follow procedures that
ensure safe metalcutting operations. The information
included throughout this catalog under the heading
“Technical Data” and other recommendations on
machining practices referred to herein are
only advisory in nature and do not constitute

Modified bottoming chamfers
are preferred whenever sufficient drill
depth exists. The additional chamfer threads significantly reduce
cutting forces, minimizing breakage and increasing tool life.
Bottoming chamfers are the least efficient
chamfer for blind hole tapping.

THREADING: Longer Lengths of Thread Engagement
ASME B 1.1 permits the use of larger drill sizes depending upon the depth of the hole to be
threaded. This can be a great advantage for both minimizing tapping problems and extending
tool life. Allowances are for 1/3 to 2/3, 2/3 to 1 1/2, and 1 1/2 to 3 times the diameter. You can
find these specific sizes at the top of each page of the Greenfield Screw Thread Manual
(EDP GI039) for each tap size, or by contacting T

THREADING: Simplified General Purpose Drill Formula for Metric Taps
The drill formula for metric taps is:
Basic Major Diameter – the Pitch = Hole Size
For example, a M5 X 0,8 thread would be calculated as follows:
5,00mm - 0,80mm = 4,20mm hole size
Simply select the closest available drill size. The hole produced will yield
approximately 70%-75% of thread.

Hole Tapping
EM taps for 3B class of fit are suitable for UNJ Aerospace internal threading applications.
TAPPING: Tap Hook and Relief
Four basic design features are incorporated into the design of all cutting tools, including taps. They are
cutting face (hook), relief, base material, and surface treatment or coating. This tip discusses hook and relief.
The
cutting face, or hook, is that portion of the tap flute between the major and minor diameter of the
thread that cuts or shears the workpiece material. The entry angle of the cutting face into the workpiece
material is measured in degrees, from positive to negative, from a perpendicular reference line through the
axis of the tool. Positive hooks are used for soft materials such as aluminum, mild steel, and stainless that
produce continuous (stringy) chips. Due to the positive angle, the cutting faces are fragile and may chip
easily. Negative hooks are used for materials that produce broken or powder chips, or those that have been
hardened. This type of cutting face is much stronger and is less prone to chipping.
The
relief of a tap may be found on the chamfer's major diameter (required for tapping), or in the threads,
in the form of radial clearance or back taper. Radial or thread relief is the thinning of the tooth from the
cutting face to the heel to relieve cutting pressures and friction across the land of the tap. Thread relief is
applied for materials that are tough, hard, or have high elastic memory (shrinks or squeezes the tap creating
friction). Back taper is the reduction of the major, pitch, and minor diameters from the first thread at the
front of the tap to the last thread near the shank. While thread relief is applied for specific applications,
back taper is applied to all taps.

TAPPING: Tap Design/Applications
Today, it seems as though there are as many tool designs as there are part materials to be tapped. However,
a closer look at the geometry of the various specialty taps developed for these materials reveals a few basic
design philosophies:
A. The most common and easiest to machine materials are soft, ductile materials that produce long, continuous
(stringy) chips. They range from non-ferrous such as aluminum and copper, to mild to medium alloy steels, and
also include some free machining stainless steels. These materials are easy to cut, produce minimal heat, and
are not very abrasive. Taps for these materials are designed with medium to high hook cutting geometry and
minimal or no thread relief. They are made from general purpose high speed steel such as M1 or M7, with
either an oxide, nitride surface treatment or Titanium Nitride (TiN). Most GP taps, or those for stainless, fall into
this category.
B. The second group of materials includes heat-treated ferrous materials, generally above 275 Bhn. These
materials are generally abrasive and do not produce chips easily, and heat generated during cutting becomes a
consideration. Taps for these materials are designed with low or negative hook cutting geometry, relief to
generate a chip, and require heat-resistant cobalt or tungsten based HSS such as M42, Rex 45, or T15. Thin film
coatings TiN, TiCN, TiN+CrC/C and TiAlN are often preferred for lubricity, heat resistance, and abrasion resistance.
Heavy duty and HP taps for hard alloys are designed with these features.
C. Tough alloys such as nickel and titanium make up the third group. While generally not hard, these materials
exhibit a toughness that makes it very difficult to produce a chip. They also have more elastic memory (closing in)
which causes friction and heat, are quite abrasive, and easily work harden. The chips produced are generally
long. The taps designed for this group are similar to those for hard materials, but the hook and relief are often
higher to reduce friction and heat. When tapping materials such as titanium, higher H limits are recommended to
overcome shrinkage.
D. The last category includes materials that produce very broken chips or powder, such as cast iron or brass.
Because these materials are cast, they are abrasive but soft. The taps for this group normally feature a low or
neutral hook, and no relief, other than the back taper, is required. General purpose HSS is often sufficient, and
either a nitride surface treatment or one of the thin film coatings such as TiN or TiCN helps with abrasion resistance.

NEW TAP COATING: Titanium Nitride + Chromium
Carbide Carbon (TiN+CrC/C)
Titanium Nitride + Chromium Carbide Carbon (TiN+CrC/C) is a new proprietary coating that
combines the wear resistance of smooth TiN coating with a lubricious top layer of chromium
carbide carbon. Effective in stainless steel and non-ferrous materials, including aluminum and
titanium, this new coating has a hardness of 2300 Vickers and is black/gray in color.
Use TiN+CrC/C coating to extend tap life when tapping 304, 316 stainless steels, wrought and
silicon die cast aluminums, titanium, and titanium alloys.

TAPPING: Tapping Titanium
T
itanium and titanium alloys are most often found in aerospace applications due to their light weight
and high strength. However, other industries are discovering the benefits of titanium as well.
One of the characteristics that makes titanium difficult to tap is its tremendous elastic memory. During
tapping, the material closes tightly around the cutting tool, generating friction and heat, and resulting
in increased wear of the cutting edges. This material also easily work hardens.
To successfully tap titanium, consider the following:
Choose a tap specifically designed with additional clearance to overcome the extreme elastic memory
of the material. Tap clearances would include extra back taper of the threads from the front to the
back of the thread section, full radial clearance in the threads across the tap lands, and additional
relief in the tap chamfer area. All of these features are used to reduce friction and heat.
In some cases, larger H limits might be required to overcome the shrinkage.
Choose a tap made from premium grade materials to prevent heat and wear resistance. Greenfield
Tap and Die offers these in our standard product lines.
TiN+CrC/C surface treatment was developed to improve tapping performance in titanium alloys.
Lubrication and proper pre-tapped hole size are vital to success. Use a compatible tapping fluid that
provides plenty of lubrication to reduce friction.
Select a drill that will produce the largest hole size allowed by the thread class callout (2B or 3B).
Due to the additional clearances required, positive feeding of the tap is highly recommended.

THREADING: Shrinking Threaded Holes
At times, threaded holes will “close in” or shrink due to either heat or build-up. In both cases, the threaded
hole becomes tighter in the process. To correct this condition, use a slightly larger tap to compensate for
shrinkage. This practice is common for parts to be plated.
If build-up occurs, try this simple solution: Multiply the amount of build-up by four, and then increase the tap’s
H limit size accordingly. For example, if the build-up equals .00025” build-up, then .00025 x 4 = .0010. .001” is
equivalent to two H limits; therefore, if you were using H6, you should use H8.
If the shrinkage occurs due to heat, the solution is to use a larger tap. While there is no formula that will give
you an exact number for choosing a larger tap, our recommendation is to use your GO gage as a guide. If the
GO fits snugly, but still enters all the way, one or two H limits should be sufficient. If the gage locks up tight
from the start, then three, four, or more H limits are probably necessary. (Each H limit is .0005” larger than the
previous one.)
One important note regarding heat shrinkage: When parts shrink, they shrink in ALL directions. A threaded
hole affected by heat shrinkage will get smaller in diameter and also shrink along the axis of the thread,
producing less than the desired pitch thread. (Think of this as if you were compressing a coiled spring, making
the distance between each coil smaller
.) The ef
fect would be similar to attempting to screw a 1.5mm pitch
thread gage into a 1.25mm threaded hole. While this kind of error isn’t overly significant, it does happen.
Refrain from choosing a tap with a long lead, anticipating that it will shrink to normal after heating.
Generally
, the configuration of the part determines the amount of shrinkage. W
e recommend starting with a
tap that is a few H limits larger to see how it gages.

THREADING: Tap Drill Charts – The Right Information?
While many factors contribute to tap failure, drill hole size is one that is often overlooked. When a
problem arises, you may check the drill size being used against a tap/drill chart. If it appears correct,
you might look for some other cause for the failure. But, are the tap/drill charts giving us the
right information?
First, it is important to note that these tap/drill charts were developed in the 1950s and 60s. Drill
diameters for the various thread sizes were selected based upon the "probable" hole size a standard
bright jobber drill with a conventional point would produce. For example, a #7 (.201") diameter drill
used for a 1/4-20 thread would generally produce a hole that was approximately .004" larger than the
drill’s diameter, or about .205". Comparing that to the .196-.207 hole size required for that tap, the #7
drill produces a hole near the maximum limit, which is ideal. This results in an approximate 70% thread
height. Removing most of the excess material with the drill significantly reduces the load on the tap
without reducing the strength of the thread.
Today, things have changed significantly. There are many advanced drill designs, materials, points,
coolant holes, and coatings. The accuracy of all drills has also improved dramatically due to enhanced
drill manufacturing equipment and processes. Today's advanced drills, powered by more accurate, high-
speed, computer-controlled machine tools, are producing holes much closer to, or even the same as, the
actual size of the drill.
Using modern drills, CNCs, and holders with conventional drill charts could result in tap breakage where
none existed before. The #7 drill may no longer be the correct drill size for a 1/4-20 thread. It may be
producing a hole much too small for successful tapping. While it is recommended that the tap/drill chart
be used as a reference, or starting point, for selecting a drill diameter for the best hole size, the finished
hole size is the most important factor. In the case of the 1/4-20 thread, any drill that produces a hole
close to .207" could be used. Even a #5 (.2055") or a special diameter may be acceptable based upon the
drill design and conditions.

THREADING: Selecting Coarse vs. Fine Threads
Coarse Thr
eads:
Coarse threads are commonly used in applications requiring rapid assembly or disassembly and when corrosion
or damage from handling or use is likely to occur
. They allow for easier starting with less cross threading. In
relatively low-strength materials such as cast iron, aluminum, magnesium, brass, bronze, and plastic, coarse
threads provide more resistance to stripping than fine or extra fine threads. If subjected to heat, they are less
likely to seize than fine threads.
Fine Threads:
Fine threads are commonly used for nuts and bolts in high-strength applications. While applications vary, in
general, fine threads are approximately 10% stronger than coarse threads. They have less tendency to loosen
under vibration because the smaller lead or thread helix angle provides better wedging action when the
assembly is tightened. Fine threads are also used for fine adjustment and thin-walled applications due to
the shallower thread height. The shallower thread height lowers the chip load per tooth and chip volume,
resulting in less tapping torque and breakage, particularly in dif
ficult to machine materials. Less chip volume
also means that more lubrication will reach the cutting teeth yielding longer tap life. Fine threads are
generally easier to tap but require a larger tap drill than coarse threads, which improves the performance
of the drill and tap.

BASIC MACHINING: Coolant Considerations
Although Greenfield Tap and Die manufactures cutting tools and not coolant, we understand
how coolant can dramatically affect the performance of our tools and, ultimately, the cost of
your operation.
Coolant performs two basic functions when used in drilling, milling, and threading applications:
1) to reduce the heat generated during cutting, and 2) to lubricate and reduce friction between
the chip and the tool.
Coolant, which is mostly water, helps to cool the chip when it is sheared away from the
workpiece. It includes a small amount of oil which acts as a lubricant to improve the surface finish
and evacuate cut chips from the flutes.
Because excessive heat and friction can dull a tool, coolant helps to extend tool life. Using the
recommended water/oil ratio is important. Too often, users will alter this ratio significantly in an
effort to reduce cost. This can cause tool life to decrease rapidly. For example, a drill which
normally yields thousands of holes, may now only last for a few hundred holes.
When selecting a coolant, choose one that is suitable for both the material and the particular
machining operation and follow the manufacturer’s mixing recommendations. For example,
high-speed machining with carbide tools might require coolant, while tapping might require
cutting oil.

THREADING: Proper Tap Lubrication
To produce high quality threads, it is important that the tap be well lubricated. A good tapping fluid
helps to minimize galling and "built-up edge" (BUE), allowing the cutting edges to remain sharp,
produce a smoother finish, and provide better size control in the part. It also reduces the friction
that generates heat and affects tool life and helps to evacuate chips, allowing the tool to run at
higher speeds.
Generally, for best tap performance, straight cutting oil should be used. For non-ferrous and
non-metallic materials, a coolant or a cutting fluid (light oil or soluble oil) is recommended.
Often, machining centers are equipped with a coolant or a cutting fluid that contains enough water and
oil to provide adequate cooling and lubrication for a variety of tools and workpieces. However, most
soluble blends are not suitable for tapping applications. Tapping, especially with thread-forming taps,
requires more lubrication than cooling. A coolant or cutting fluid might lack the lubrication necessary to
obtain acceptable tool life and part finish.
One method for increasing the lubrication of soluble oils is to use special-purpose additives. Consult your
coolant specialist for recommendations.
After you select the proper coolant, cutting fluid, or cutting oil, it is also important to choose the right
method of application and pressure. For tapping, use more than one nozzle around the tap. The nozzles
should be located as close to the surface of the part as possible, be positioned at an angle close to the
axis of the tool, and point directly into the hole to flush the chips from the flutes. Brushing or squirting
oil or fluid onto the tap does not provide sufficient lubrication. In fact, heavy viscosity oil may cause the
chips to "stick" or "cling" to the tap, increasing the chance of breakage.

Features/Benefits:
patent-pending helical flute design
that reduces thread chatter, improving
product thread finish and quality
made from high-quality powder
metal material
standard TiAlN coating allows
faster speed and feed rates for
higher productivity
same tool is capable of generating
- both right hand and left
hand threads
- several thread diameters for the
same TPI
- different class of fits with
a CNC offset
- both bottoming and through
hole threads
provide a greater percentage of
engagement than HSS or carbide taps
perform well in materials < 30 Rc
Application Information:
superior performance over carbide
thread mills in these applications:
- interrupted cuts - chipping is less
likely to occur due to tougher
PM substrate
- less than ideal machining
conditions, i.e., slower
spindle speeds
- small job/lot sizes where
tool cost does not justify
use of a carbide threadmill
the ideal choice when:
- material has proven difficult
to tap
and is < 30 Rc, including:
non-ferrous materials
low carbon steels
ductile cast iron
- thread specification calls for full
threads close to bottom of hole
- thread specification requires a
special tap
- small lot size to be threaded

THREADING: Controlled Feed Rates When Thread Milling
For thread milling applications, we recommend setting controlled feed rates within the program for the
centerline of the spindle or tool. This method ensures absolute feed control of the tool through the
entire thread milling operation.
As the tool moves around the centerline of the bore, the tool centerline must traverse at a slower IPM
rate than the periphery of the tool at the cutting edge or major thread diameter. If the standard feed
rate of RPM x feed per flute x number of flutes was applied to the spindle centerline, the tool would
have an effective feed rate at the cutting edge that may exceed the capability of the thread mill,
resulting in poor tool life and possible breakage. The programmed feed rate for the centerline is based
upon the thread mill diameter selected. The larger the tool diameter, the greater the reduction required
to ensure the proper operating parameters on the periphery.
Feed Compensation Formula for Internal Threading:
Centerline IPM
2
= IPM
1
x (Major Thread Diameter - Tool Cutting Diameter)
Major Thread Diameter
Feed Compensation Formula for External Threading:
Centerline IPM
2
= IPM
1
x (Major Thread Diameter + Tool Cutting Diameter)

For indexable thread mills, refer to chart for starting speeds only. Feed rate should start at 0.0015” per flute for cutting diameters less than 1.00”. For diameters 1.00”
and larger, 0.0020” is recommended. For all taper pipe threads, reduce speed and feed chart values by 30%.
* Not recommended for these materials.
Minimum feed rate for any thread mill is 0.0003” per flute. If severe conditions are present, first reduce feed per tooth, then reduce speed. The speeds & feeds shown are
recommended as starting parameters only. Condition of material, machine rigidity, part fixturing, tool overhang, and material hardness should all be considered before
attempting any machining operation.

THREADING: Selecting Thread Mill Diameters
When producing internal threads, selecting the right thread mill diameter is key to operating
efficiency. Thread mills are usually offered in several cutting diameters for a given threads per
inch (TPI).
Generally, for coarser pitches (coarser than 14 TPI), select a cutting diameter no larger than
70% of the nominal thread size to be produced. For finer pitches, the thread mill can be as
large as 75% of the nominal diameter
. Although the tool has radial clearances similar to end
mills, if the tool diameter is too close to the thread diameter, the tool may rub and produce
more heat, resulting in excessive wear. This rubbing may also distort the thread form affecting
the thread angle.
When choosing a thread mill, it may not be necessary to use the largest one that will fit the hole.
The larger diameter thread mill will minimize deflection, particularly on coarse thread series, but
is more prone to rubbing and chip congestion. A smaller mill will remove more cubic inches of
metal than a larger one, resulting in greater efficiency and productivity. There will be more
clearance for the tool and more space for coolant and chips. However, for optimum results, the
tool may need to rotate much faster than the capability of the machine. Also, the thread length
of the tool may be too short for the thread depth required.

Helical thread mills reduce chatter.
In performance testing, helical flute thread mills outperformed conventional thread mills.
The threads on the left were cut by a Greenfield helical thread mill, while the threads on the right
were cut by a competitor’s conventional thread mill. Notice the chatter on the competitor’s
workpiece. The helical tool was so quiet, the operator wasn’t sure it was cutting!
Choose the proper style of thread mill for your application.

Metric Hand Taps
Features/Benefits:
the most popular style of tap
manufactured from select high-speed
s
teel for increased wear life
straight flute design
can be used by hand or for tapping
under power
versatile taps for use in general
machine tapping or CNC tapping
applications
use for through hole or blind hole
tapping
standard in right hand sizes in Unified
and American National thread form
hand taps store chips in their flutes
next to the chamfered teeth during
the threading operation
for deep-hole threading more than
1 1/2 diameters of the tap-in depth,
use a hand tap with fewer flutes for
increased chip handling capabilities
Metric taps for 6H class of fit are suitable for MJ Aerospace internal threading applications.
Metric taps are manufactured to USCTI specifications and dimensions.
Metric tap blank dimensions are equivalent to inch taps.
Metric hand taps with plug chamfer begin on the next page.

Series No. 5353 Uncoated
Hand taps are available in three
chamfer lengths for through hole or
blind hole tapping:
taper (7-10 pitches) - longest
standard chamfer ensures easier
starting and requires less
t
apping torque because of more
w
orking teeth
plug (3-5 pitches) - the most
u
niversally used chamfer for
hand or machine tapping in
through or blind holes
bottoming (1-2 pitches) - for
threading close to the bottom of
blind holes; the least efficient
standard chamfer
Application Information:

The Tru-Lede Fe family of taps was
d
eveloped in our test laboratory
through extensive research and
design evaluation. This new form
tap family requires lower torque to
form threads and will perform at
two times the tapping speeds
recommended for threading with
more conventional cutting taps.

THREADING: Why Are “H” Limits for Roll Form Taps Higher
Than for Cut Thread Taps?
Roll form tapping is an effective way to produce internal threads in production applications.
There are many benefits to this process, including the absence of chips. Before proceeding with
roll form tapping, consider the material to be tapped, the hole size before tapping, the machine
capabilities, and the class of fit requirement after tapping.
In the case of fit, the requirement for the finished thread is the same regardless of whether it is a
cut or rolled form thread. Use 5/16-18 2B internal thread as an example. 2B is the designation for
internal thread minimum and maximum values after tapping. It is normally checked with GO and
NOT GO thread gages. For cutting this thread, the recommended tap “H” limit value is H-5; but,
when roll forming the same thread, the recommended value is H-7. There are published charts in
our catalogs detailing other sizes and for recommendations.
The reason for the larger “H” value is the slight shrinkage that occurs in the hole after the tap is
removed. All metals have a memory and will try to spring back to their original shape. When
displacing metal using a roll form tap, this condition will occur. The higher “H” limit compensates
by forming a slightly larger thread which shrinks slightly after the tap is removed. Other factors
may interfere, but, generally, the recommended “H” limit values published for cut or roll form
threads will deliver acceptable gaging results.

THREADING: Pipe Taps… How Deep to Thread?
Do you know how deep to run a pipe tap into a drilled hole before it stops? In other words, do you
know when the pipe thread is either too small to accept the L-1 thread plug gage, or too large to
be flush with the surface of the hole being tapped within ± 1 turn on the gage?
Pipe threads are sized differently than standard straight threads. They are based on the basic size
at the top of the threaded hole produced by the pipe tap. The basic size, commonly called the
12-thread count, occurs approximately 12 threads from the front of the taper pipe tap. This means
you can run any standard projection pipe tap into a drilled hole approximately 12 threads from the
front of the tap, which should be the approximate basic size for that pipe thread.

THREADING: Determining the Minimum Tap Drill Depth
The tap drill depth for tapped holes should be deep enough to allow for the minimum thread depth,
the tap’s chamfer, any chips that may accumulate in the bottom of the hole, and any over-travel of the
spindle as it slows to a stop before reversing.
To determine the ideal minimum drill depth, start with the basic rule: the tap drill depth should be at
least one thread or one pitch beyond the chamfer of the tap. In other words, for a 1/4-20 tapped
hole requiring a 3/8" (.375") thread depth, using a two-thread bottoming chamfer with a length of
.100", and adding a minimum of one additional thread or .050", the minimum drill depth would be
.525" (.375 + .100 + .050 = .525").
It is important to note that using the “one-pitch rule” does not always prevent the tap from hitting the
bottom of the hole. In this case, consider the following three factors:
1) Understand the machine’s capability to stop the spindle rotation at the bottom. Many newer machines
are able to stop and reverse in one-half turn or less. If this is the case, the “one-pitch rule” may be
sufficient. However, an older machine may allow the spindle to over-travel one, two, or even three
pitches. Here, the additional drill depth should be at least one pitch beyond the over-travel amount.
2) Consider how the chips are produced. Spiral taps extract chips, preventing them from accumulating in
the bottom of the hole. Chips produced from straight flute hand taps are likely to be flushed to the
bottom by the coolant. The front of the tap may bottom on these chips, chipping or breaking the tap.
In this case, one diameter of additional depth is recommended.
3) Understand the tap design. If using a plug or taper chamfer, note the tap sizes through 3/8"
diameter are manufactured with 90° external centers that could hit the bottom. A general rule
is to add one-half the diameter to the length for sufficient clearance.
Metric taps are manufactured to USCTI specifications and dimensions.
Metric tap blank dimensions are equivalent to inch taps.

GAGING: TiN (Titanium Nitride) Coated Plug Gages
When are TiN-coated gages recommended?
1. When the product material is abrasive (causing excessive wear on the gage), or in any high-
volume application where there is continuous or frequent usage. The extra hard surface and
lubricity of titanium nitride greatly extend the wear life, by as much as 10 times, permitting
longer frequencies between recalibration. The gold color is a wear indicator. When the gold
is worn of
f, the gage is undersized.
2.
Due to its inert, hard characteristics, titanium nitride provides a high resistance to corrosion,
making it ideal when humidity and other atmospheric conditions create corrosion problems.
3. When gaging, certain soft materials or plated product threads tend to "load up" on the
flanks of steel gages. The lubricity properties of TiN greatly aid in preventing this buildup.
When is TiN better than chrome?
1. TiN is harder than chrome; therefore, it is more wear resistant.
2. TiN provides better lubricity than chrome, cutting down wear and galling.
3. TiN is a more uniform coating than chrome, eliminating possible uneven buildup on the
gage flanks.
4. TiN does not gall in aerospace-type materials.
5. TiN-coated gages outlast chrome gages by as much as 8 times.

GAGING: Threaded Holes
To confirm the accuracy of a tapped hole, always use a GO-NO GO gage. Never use a fastener (screw
or bolt). Using a screw or bolt will not allow you to verify the size of the thread produced, only indicate
that the bolt used will fit in that particular hole. GO-NO GO gages can give indications as to whether the
thread produced is within the thread specification. A screw or bolt is not capable of giving such an
indication. Accurate gages will also help predict remaining tool life by indicating tightness or looseness
of the gage in the part.

THREADING: H Limits vs. D Limits
H limits are a sequence of numbers in .0005" increments larger than the minimum limit of the part,
starting with H1. An H1 limit is one .0005" increment larger than the minimum limit or GO gage, an
H2 is two .0005" increments (or .001) larger, an H3 is three .0005" increments (or .0015"), and so on.
The recommended H limit for a particular size should be approximately 40% of the thread tolerance
larger than the minimum limit of the thread.
D limits are similar to H limits and follow the same numbering system. However
, H limits are used
primarily for inch threads, while D limits are used exclusively for metric threads. As is the case with H
limits, D limits are a sequence of numbers in increments larger than the minimum limit or GO gage,
but the increments are .013mm or .00051". Starting with D1, a D1 is one .013mm increment larger, a
D2 is two .013mm (or .026mm) increments larger, and so forth. As with inch threads, the “40% rule”
is applied based upon the tolerance or class of thread.
There are two primary differences between H limits and D limits. First, D limits are slightly larger than
H limits. Second, the tap manufacturing tolerances are different. An H or D limit number defines the
maximum size of the tap. A tap manufacturing tolerance is then applied to establish the minimum
limit. For H limit taps, the tolerance is minus .0005" for all sizes through 1" diameter. Tap tolerances
for D limits are larger for all thread sizes. The smallest tolerance is .015mm (.00059”) and becomes
larger with the diameter. For example, an M3 has a .015mm (or .0006") tolerance, an M6 has a
.020mm (or .00079") tolerance, and an M20 tap has a .041mm (or .00161”) tolerance. That is over 3
times the amount of tolerance of an equivalent 3/4" tap.

NPTF (Dryseal) Taper Pipe Gages
Dryseal pipe threads are generally used in more critical
applications than NPT threads; therefore, a greater
variety of gages and/or measuring equipment is used
to more adequately check size, taper
, and thread form.
L1 and L3 plugs are supplied with one step as standard.
L1 = Length of engagement in hand tight make up.
L2 = Length of ef
fective thread (external).
L3 = Length of three threads beyond L1 for wrench make up.
When ordering, please use EDP numbers.

Properly Handling Gages
C
lean the part before gaging to remove dirt and chips.
Do not force the gage; use reasonably light pressure only.
Protect the gage from damage; nicks and burrs allow inaccurate results.
Keep the gage clean and lightly oiled to increase wear life.
Avoid direct handling of gaging surfaces; fingerprints cause rust.

Features/Benefits:
m
ade-to-order using American Gage
Design (AGD) Standards
AGD Style No. 1 features bilateral
tolerance (split plus and minus)
AGD Style No. 2 features unilateral
tolerance (GO and NO GO on one
member)
AGD Style No. 3 is the same as
Style No. 1, but in shorter lengths
(unilateral tolerance)
precision lapped for overall
accuracy, finish, and wearability
of the gaging surface
roundness and taper of all gages will
not exceed 50% of the applicable
gagemaker's size tolerance and are
non-accumulative
composition insulating grips for
ease of handling
series 1685 and 1690 feature relief
on gage ends to avoid wear
when handling
premium 5-day manufacturing service
is available (.151
through 4.000);
specify at time of order
Gage Tolerances:
s
election of gage tolerance should
be in relation to the amount of
tolerance on the product being gaged
the normal rule of thumb is that gage
tolerance should not exceed 10% of the
product tolerance equally divided
between the GO and NO GO conditions
these gages are furnished in three
classes of tolerance:
Class XX: used where product limits are
extremely close, or for master gages
Class X: used where product limits
are relatively close, or occasionally
for master gages
Class Y: used where product limits
are normal to liberal
application of tolerances
(unless otherwise specified):
NO GO = Plus

*The values listed for 1A/1B, 2A/2B, and 3A/3B are from ASME B1.1-1989 Unified Inch Screw Threads (UN and UNR) Thread Form. A few
of these values have changed due to revisions in ASME B1.1-2003. These revisions are the result of applying the standard practices for
calculating and rounding screw thread dimensions. By establishing this practice, all parties using a calculator, computer spreadsheet
program, or any other means, will derive the same values.
The values from past issues of B1.1 along with the revised values are both considered acceptable until future revisions of B1.1 make the
revised values the only acceptable values.
Values for B1.1 - 2003 can be calculated by adding or subtracting the values where indicated:
(a) +.0001 (b) -.0001 (c) +.0002 (d) -.0002

The Proper Use and Care of Gages
Limit-type thread plug and ring gages are important tools in
any Quality Control program. These gages are used to
determine whether a product's threads fall within maximum
and minimum functional size limits.
P
roduct size limits are expressed in terms of pitch diameter,
w
hich is theoretical. Limit-type gages check the "functional"
size of the threads, or the capability of product threads to
assemble with mating parts, and the degree of tightness or
looseness of the fit. Functional size takes into account not
only the pitch diameter, but also the effects of deviations in
other factors such as lead, angle, roundness, and helical path.
Decisions regarding whether to accept or reject a product are
made based on its functional size. Obtaining an accurate
functional size evaluation depends upon three key factors:
1) the accuracy of the gages used, 2) proper care of the
gages, and 3) correct use of the gages.
Gage Accuracy
The initial accuracy of the gage is the responsibility of the
gage manufacturer, who should manufacture the gage
within specified allowable tolerances. Maintaining gage
accuracy then becomes the responsibility of the user and
involves properly caring for and correctly using the gages.
Properly Caring for Gages
Gages should be handled with care to avoid damage and
premature wear. Mishandling gages can result in unnecessary
costs, both for replacement gages and, more importantly, for
improperly rejected products. Gages should also be calibrated
regularly to ensure they are within acceptable tolerances.
Use the following tips to properly maintain your gages:
1. Keep gages clean and lightly oiled, if possible, both
during use and when in storage. Light oil will prevent
rusting, greatly increase wear life, and help to prevent
"loading" or "smearing" of product material onto the
gage threads. (In some applications, using oil on a
workpiece might not be acceptable, so be sure to check
the material specifications before using an oiled gage.)
Using Seal Peal plastic dip on gage threads in storage is
also acceptable.
2. Protect gages from nicks, jams, and other damage by
providing a protective box in the work area.
Using Gages Correctly
Correctly using gages will not only extend their life but also
yield accurate results when evaluating threads. Refer to the
f
ollowing usage tips:
1) Clean parts before gaging. Remove any dirt or chips so
the gage can check product size unaffected by foreign
material.
2) Align and start threads carefully. Cross-threading can
damage the end threads of both the product and the gage.
3) Gages are not sizing tools! They must travel over the full
length of the product threads or, in the case of blind holes
or imperfect run-out threads, they should travel as much of
the length required to enable assembly.
4) GO gages must enter or be entered by product threads
without undue force or pressure.
5) NO GO gages have limitations on entry. It is usually
preferable that they do not enter; however, some entry is
generally allowable and the limitations vary for different
gage standards. For inch threads, NO GO entry is limited to
not more than 3 turns; for metric threads, NO GO entry is
limited to not more than 2 turns.
6) Don't force the gage. Use reasonable light pressure only.
7) Use thread ring gages equally from both faces. We often
find that ring gages submitted for re-inspection or
reconditioning are tapered from wear only on the stamped
side. The ring gage is designed to be used from either face,
and alternating use from each end will prolong wear life.
By properly using and caring for your gages, you can
achieve a number of sound, economical benefits:
-
Prolonged wear life
-
Extended periods between calibrations
-
More reliable results in evaluating product threads
-
Acceptance of the maximum size range of the
product tolerance
-
Preventing defective threads from reaching
the market

Special Taps
Unless otherwise specified:
Special taps over 1.010" to 1.510" diameter inclusive, having
14 or more threads per inch or 1.75 millimeter pitch and
finer, and sizes over 1.510" diameter with 10 or more
threads per inch or 2.5 millimeter pitch and finer, are made
to general dimensions shown in USCTI Table 303.
Special tap thread limits are determined using the formulas
shown in USCTI Table 331 for Unified Inch Screw Threads and
USCTI Table 341 for Metric M-Profile Screw Threads.
NOTES
Tap sizes .395" and smaller have an external center on the thread end (may be
removed on bottoming taps). Sizes .125" and smaller have an external center
on the shank end. Sizes .224" thru .395” have truncated partial cone centers
on the shank end (length of cone approx. 1/4 of diameter of shank). Sizes over
.395" have internal centers on both the thread and shank ends.
For standard thread limits and tolerances for Unified Inch Screw Threads see
USCTI Table 327 and for Metric Threads see USCTI Table 337.
For eccentricity tolerances of tap elements see USCTI Table 317.

Applying the proper lubricants in tapping operations
can result in longer tap life, increased production, better
workpiece size control, smoother and more accurate
threads, less resharpening, and more efficient chip removal.
Generally, for best tap performance, straight cutting oil
should be used. For non-ferrous and non-metallic materials,
a coolant or a cutting fluid (light oil or soluble oil) is
recommended.
Often, machining centers are equipped with a coolant or a
cutting fluid that contains enough water and oil to provide
adequate cooling and lubrication for a variety of tools and
workpieces. However, most soluble blends are not suitable for
tapping applications. Tapping, especially with thread-forming
taps, requires more lubrication than cooling. A coolant or
cutting fluid might lack the lubrication necessary to obtain
acceptable tool life and part finish. Consult your coolant
specialist for recommendations.
After you select the proper lubricant, it is also important to
choose the right method of application and pressure. For
tapping, use more than one nozzle around the tap. The
nozzles should be located as close to the surface of the part
as possible, be positioned at an angle close to the axis of the
tool, and point directly into the hole to flush the chips from
the flutes. For horizontal tapping, where the tap is stationary
and the workpieces is rotating, consider using two streams of
lubricant, one on each side of the tap.

Reprinted with permission from United States Cutting Tool Institute (USCTI).
Whether you are tapping vertically, horizontally, or on an
angle, make sure the lubricant reaches the cutting lands of the
tap at all times, especially at the point or chamfered portion.
Brushing or squirting oil or fluid onto the tap does not provide
sufficient lubrication. In fact, heavy viscosity oil may cause the
chips to "stick" or "cling" to the tap, increasing the chance of
breakage. In addition, when the lubricant is automatically
applied only on the forward motion of the tap, you should
time the application of the lubricant so that it will reach the
hole before the tap starts to cut. This applies particularly to
machines on which the cutting fluid is automatically shut off
during the tap’s reversal.
For maximum effectiveness, it is often best to force the
lubricant into the hole under pressure. The amount of pressure
applied varies depending on the tapping method, hole depth,
and tapping speed.
Try to keep tapping lubricants as clean as possible using a
filtering system or other equipment. Dust and other foreign
particles can contaminate the oil and decrease its effectiveness.
Be sure to thoroughly clean machines and oil tanks when
adding new lubricant and at regular intervals to ensure
optimum tapping results.

General purpose pipe taps are appropriate
for threading a wide variety of materials,
both ferrous and non-ferrous.
Ground thread pipe taps are standard in
American Standard Pipe Form (NPT) and
American Standard Dryseal Pipe Form
(NPFT). NPT threads require the use of a
sealer, like Teflon® tape or pipe
compound. Dryseal taps are used to tap
fittings which will give a pressure-tight
joint without the use of a sealer.
The nominal size of a pipe tap is that of
the pipe fitting to be tapped, not the
actual size of the tap. The thread tapers
3/4” per foot.
All pipe taps are furnished with 2 1/2 to
3 1/2 thread chamfer.
NOTE:
*Distance small end of tap projects through L1 Taper Thread Ring Gage.
**Recommended size given permits direct tapping without reaming the hole, but only gives a full thread for approximately the L1 length.

Nitride
(MAXI #1)
Hardened case extends wear life in abrasive
materials. Use for aluminum and other non-ferrous
materials.
Avoid on taper pipe, fast spiral, and small
diameter (<#6) or fine pitch taps due to tendency
for thread chipping.
Oxide
(SH-50)
Helps prevent galling in ferrous (iron-based)
materials. For free machining steel. Use for steels,
stainless steels, and irons.
Has a tendency to cause galling in non-ferrous
materials such as aluminum.
Nitride and Oxide
(SH-47)
Combines the benefits of nitride and oxide surface
treatments. For steels, stainless steels, and nickel
alloys.
See precautions for nitride and oxide surface
treatments.
Titanium Nitride
(TiN)
Proprietary TiN coating (hardness 2300 Vickers) offers
significantly improved wear life and thread finish,
often at higher tapping speeds, in a broad range of
materials, especially steels, irons, and plastics.
Golden color.
Use with caution in non-ferrous materials such as
aluminum because of tendency to gall.
Titanium
Carbonitride
(TiCN)
Proprietary TiCN coating (hardness 3000 Vickers) is
harder, tougher, and more wear resistant than TiN
under conditions of moderate cutting temperatures.
Like TiN, TiCN may be used at higher cutting speeds
in a broad range of materials, especially steels and
irons. Blue-gray color.
Use with caution in non-ferrous materials such as
aluminum because of tendency to gall. TiAlN is a
better choice when used at extreme temperatures.
Chromium Nitride
(CrN)
CrN is medium hard (hardness 1800 Vickers) and has
a lower wear resistance than TiN, TiCN, and TiAlN.
However, unlike these coatings, CrN does not gall
when used in some non-ferrous work materials. Use
for brass, bronze, zinc alloys, and magnesium alloys.
Silver color.
Ineffective in ferrous materials.
Titanium Aluminum
Nitride
(TiAlN)
Nanolayer TiAlN coating (hardness 3300 Vickers)
offers improved wear life and thread finish, especially
in conditions where high temperatures can be
generated. Use for PH stainless steels and nickel-
based alloys like inconel. Violet-gray color.
Use with caution in non-ferrous materials because
of tendency to gall.
Titanium Nitride +
Chromium Carbide
Carbon
(TiN + CrC/C)
Proprietary coating (hardness 2300 Vickers) that
combines the wear resistance of smooth TiN coating
with a lubricous top layer of chromium carbide
carbon. Effective in stainless steel and non-ferrous
materials including aluminum and titanium. Ideal
choice for 300 series stainless steels, wrought and
diecast aluminums. Black-gray color.
Effective in both ferrous and non-ferrous
materials.

BEST: First choice among all commercially available coatings. Should provide superior results in the proper application.
ALT (Alternate): Provides a significant performance benefit over uncoated tool. This may include improved life,
productivity, size, finish, or any combination of these benefits.
POSS (Possible): Performance often application dependent. Results are difficult to predict and may be variable.
NR (Not Recommended): Not compatible with the selected material. Likely to perform worse than an uncoated
tool and the benefit may not justify the cost.
Chart applies to non-heat-treated materials, generally with hardness levels less than 275 Bhn or 28 HRc.

MAINTENANCE TOOLS PRODUCTION TAPS THREAD MILLS HIGH PERFORMANCE TAPS
Tap Chamfers
Many sizes of hand taps are available with optional fluting, or
fewer flutes than standard. Having two or three fewer flutes
provides more space for the storage of chips.
The selection of the proper tap depends entirely on the
conditions under which the tap is to be used. Try a three-
fluted tap first. Due to its construction, it is stronger than a
two-fluted tap. The two-fluted tap, having wider flutes, has
less total land width and therefore does not give as much
support in tapping as the three-fluted tap. It is also more
difficult to maintain the size of the tapped hole with a two-
fluted tap than with taps having three flutes.
Taper (7 to 10 pitches)
The taper chamfer has the
longest standard chamfer
ensuring easier starting.
It requires less tapping
torque because of more
working teeth.
Hand Tap Chamfers
Plug (3 to 5 pitches)
The most common chamfer
for use by hand or machine
in through or blind holes.
This chamfer is more efficient
than a bottoming or
modified-bottoming chamfer.
Modified-Bottoming
(2 to 2 1/2 pitches)
This short chamfer allows for
threading close to the bottom
of blind holes. Due to the
slightly longer chamfer and
more working teeth, this
chamfer is more efficient
than a bottoming chamfer.
Bottoming (1 to 2 pitches)
For threading close to the
bottom of blind holes, the
bottoming chamfer is the
least efficient chamfer
available.

INFORMATION & INDEX GAGES MAINTENANCE TOOLS PRODUCTION TAPS THREAD MILLS HIGH PERFORMANCE TAPS
In addition to the nominal size and pitch of a tap, there is
another important dimensional factor to be considered when
selecting a ground thread tap for a given job. This factor is the
pitch diameter tap limit, “H” and “L.” “H” represents (high)
above basic pitch diameter; “L” (low) is below basic pitch
diameter. Tap limits have been established to provide a choice
in the selection of the tap size best suited to produce the class
of thread desired.
Figure 1
illustrates the numbering system and the .0005”
diameter increment separation between successive limits.
Because the starting point is basic pitch diameter, dividing the
limit number by two establishes, in thousandths of an inch,
the amount the maximum tap pitch diameter is above basic in
the “H” series and the amount the minimum tap pitch
diameter is under basic in the “L” series.
Figure 2
illustrates the positioning of the tap limits in
relation to the various classes of threads for a 1/4-20 size.

Simplified Tap-Drill Formulas for Taps That Cut Threads
(for 60° Threads)
In tapping with forming taps there is no method of predicting
the percent of thread that will be obtained because of the
many variables involved. However, 55% for maximum drill size
and 75% for minimum drill size may be used as a guide, and
any desired percent of thread may be approximated by using
drill sizes in between. If percent of thread is critical, the user
must experiment to establish the desired hole size. Minor
diameter of formed threads should be within specified limits.
The formulas for determining theoretical maximum and
minimum drill sizes for average conditions are illustrated below.

The factors considered when trying to determine the best
tapping speeds are:
Material to be tapped
Length of chamfer on tap
Percentage of full thread to be cut
Length of hole (depth of thread)
Pitch of thread
Cutting fluids
Machine equipment
Horizontal or vertical tapping
The best and most efficient operating speeds for taps cannot
be calculated with the same certainty as for many other
metalcutting tools.
With other tools, the feed per revolution can be set at any
desired point and can be varied as conditions demand.
Taps, on the other hand, must always be advanced at a rate
equal to one pitch for every revolution. The style of tap may
vary the conditions. For example, with a bottoming tap, the
first thread on each land cuts the full height of thread,
while, with a taper or starting tap, a number of threads do
their share of the cutting before the full height of thread
is reached.
The depth of thread also varies, depending on the pitch. The
coarser the thread, the greater the advance of the tap per
revolution and the greater the amount of material removed.
The method of feeding the tap, and the type of equipment for
driving, also influence the permissible speeds. If taps
are mechanically fed at the proper rate of advance, they can be
o
perated at higher speeds than if they are required to feed
t
hemselves and pull some part of the machine along with
t
hem.
Speeds may be modified to take into account any or all of the
factors listed to the left.
Speeds must be lowered as length of thread increases because,
in deep thread holes, the accumulated chips increase friction
and interfere with lubrication.
Bottoming taps must be run slower than plug taps.
Tapping of full height of thread calls for slower speed than
if the commercial 75% height only is required.
Coarse-thread taps in the larger diameters should be run more
slowly than fine-thread taps of the same diameters.
The quantity and quality of cutting fluid may affect the
permissible speeds as much as 100%.
Taper threaded taps, such as pipe taps, should be operated
at from 1/2 to 3/4 the speed of a straight thread tap of
comparable major diameter.

Modern metalcutting operations involve high
e
nergy, high spindle or cutter speeds, and high
temperatures and cutting forces. Hot, flying
chips may be projected from the workpiece during
metalcutting. Although advanced cutting tool
m
aterials are designed and manufactured to
withstand the high cutting forces and temperatures
that normally occur in these operations, they are
susceptible to fragmenting in service, particularly
if they are subjected to over-stress, severe impact
or otherwise abused. Therefore, precautions
should be taken to adequately protect workers,
observers and equipment against hot, flying chips,
fragmented cutting tools, broken workpieces or
other similar projectiles. Machines should be fully
guarded and personal protective equipment should
be used at all times.
When grinding advanced cutting tool materials, a
suitable means for collection and disposal of dust,
mist or sludge should be provided. Overexposure
to dust or mist containing metallic particles can
be hazardous to health particularly if exposure
continues over an extended period of time and
may cause eye, skin and mucous membrane
irritation and temporary or permanent respiratory
disease. Certain existing pulmonary and skin
conditions may be aggravated by exposure to
dust or mist. Adequate ventilation, respiratory
protection and eye protection should be provided
when grinding and workers should avoid breathing
of and prolonged skin contact with dust or mist.
General Industry Safety and Health Regulations,
P
art 1910. U.S. Department of Labor, published
in Title 29 of the Code of Federal Regulations
should be consulted. Obtain from Greenfield
Tap & Die and read the applicable Material
S
afety Data Sheet before grinding.
Cutting tools are only one part of the worker-
machine-tool system. Many variables exist in
machining operations, including the metal removal
rate; the workpiece size, shape, strength and
rigidity; the chucking and fixturing; the load
carrying capability of centers; the cutter and
spindle speed and tor
que limitations; the holder
and boring bar overhang; the available power;
and the condition of the tooling and the machine.
A safe metalcutting operation must take all of
these variables, and others, into consideration.
Greenfield Tap & Die has no control over the end
use of its products or the environment into which
those products are placed. Greenfield Tap & Die
urges that its customers adhere to the recommended
standards of use of their metalcutting machines
and tools, and that they follow procedures that
ensure safe metalcutting operations. The information
included throughout this catalog under the heading
“Technical Data” and other recommendations on
machining practices referred to herein are
