Premium blade construction:
• Unique cutting geometry protected under Kennametal Inc. US Patent
Number 63701702 (April 16, 2002)
"Spade Blade Drill and Method
of Making"
.
• Fabricated from a pressed and HIP sintered powder metal T-15 alloy,
yielding a more uniform and consistent metallurgical structure
provides lower variability than competing blades.
Premium service and support:
• A specials program that delivers custom engineered spade
blade and spade blade holder sizes and geometries to fulfill
every customer requirement.
• A complete line of straight and helical fluted holders offered
with both straight and taper shank styles; all holders are
engineered to accommodate the option of a coolant gland for
use where coolant through the spindle is lacking.
Premium Coatings:
• TiN (Titanium Nitride) gives longer tool life and added lubric-
ity, while allowing more aggressive machining of steels.
• TiCN (Titanium Carbonitride) is a general purpose coating
well suited to machining of mild steel, ductile cast iron and
nonferrous materials such as aluminum and copper alloys.
TiCN is superior in preventing excessive BUE (built-up edge).
• “G” is comprised of more than 20 layers of TiCN and
TiAlN with an overcoat of TiN optimized for drilling
mild steel and ductile cast iron.
• TiAlN (Titanium Aluminum Nitride) a
multilayer, mixed phase coating
designed for high-speed machining
in alloy steels, high temp alloys,
gray cast iron and titanium. Perfor-
mance advantages require TiALN
coated tools to be operated at rela-
tively high speeds, typically 50% greater than other PVD coatings such
as TiN.
• CX-H is a proprietary coating designed for optimal drilling of abrasive,
short chipping nonferrous alloys (e.g. red brass, Al-Si alloys).
• Diamond coating is designed for abrasive nonferrous alloys.
Metcut spade blades give you the edge!
• Highest performance in the industry
• Faster penetration rates – 35% to 100% higher "in-feed" rates than competitors' blades
• More holes per blade – 25% to 50% wear-life improvement over competitors' blades
• Less down time
• Interchangeable with other conventional spade blades
• Improved surface finish – elimination of secondary operations
• Complete standard and specials drill body / holder offering.
• Lower variability

Application Information
T-15 HSS spade blades are recommended:
s For replacing steel twist drills resulting in 2X to 3X
higher penetration rates and up to 4X to 5X longer
wearlife.
s For providing straighter and more consistent holes
with superior surface finishes than can be produced
using either HSS twist drills or carbide indexable
drills.
s When rigidity of the machine or the fixture requires
a more forgiving, durable and tougher tool; T-15 steel
possesses a higher transverse rupture strength and is
more impact-resistant than comparable carbide
spade blades and/or carbide indexable drills.
s In applications requiring hole depths up through 15X
to 20X diameter; pecking may be required for depths
above 7X diameter for some materials.
s As a more cost effective alternative to carbide
indexable drills since T-15 steel spade blades operate
at comparable penetration rates to single-effective
indexable drills in materials <35 Rc, and one spade
blade holder accommodates multiple diameter
blades.
Carbide spade blades are recommended:
s For high productivity applications in which wearlife
must be maximized; typically limited to hole depths
less than 5X diameter.
s For use in highly abrasive materals such as cast iron,
cast aluminum, etc.; or in harder steel alloys, typi-
cally 30 to 45 Rc.
s To exceed the performance of single-effective
indexable drills by 20% to 50% in materials <45 Rc.
s To get improved productivity in contrast to T-15
steel spade blades by allowing 50% to 100% higher
speeds; operational parameters of carbide blades
recommend hole depths < 5X diameter, rigid set-ups,
and 50% to 100% higher coolant pressures.
Spade blade holders generally can accommodate a
range of blade sizes up to 1.30 to 1.35 times the
smallest blade size. It is therefore possible to cover the
entire range of hole sizes with just a few spade drill
holders. Contrast this with the inventories required for
indexable drills and steel taper shank drills.
Technical Data
Straight fluted spade blade holders are recommended
for horizontal machining center applications to
maximize chip evacuation given their inherent open
flute construction.
Helical fluted spade blade holders may be necessary
for vertical machining center applications to break
chips, enhancing chip removal.
R-8 (Bridgeport) holders and blades are used in
Bridgeport machines that require a R-8 taper holder.
Through coolant via the spindle cooling is preferable
for optimal drilling with spade blades. However, if
spindle cooling is unavailable, then coolant glands or
inducers should be used to provide through coolant
capability. All METCUT spade blade holders are
manufactured with both the option of through the
spindle cooling or with a rotary coolant gland. Flood
coolant is not recommended, but can be used for very
short hole depths, less than one diameter. Through
coolant
must
be used with spade drill depths greater
than one diameter.
Half-size spade blade holders (see pages 16–20) may
be required where the penetration rate (in-feed)
exceeds the recommended values by more than 25%.
They are also recommended for use in gummy materi-
als (e.g., aluminum, copper alloys) where torque
forces can exceed the yield strength of the spade
blade holder, typically where the spade blade diam-
eter exceeds the spade blade body diameter by more
than 25%. Without half-size holders, the spade blade’s
excessive overhang can expose it to premature failure
and the holder to potential catastrophic break-up.
Series 0, 1 and 2 spade blade diameters have both full
size and half size holders that provide proper support
to the blade under most circumstances. Standard full-
size holders can accommodate the full diameter range
for a given spade blade series. Half-size holders
should be used only for blade diameters that exceed
the half-size spade blade holder body diameter by at
least 0.010".

Minimum Coolant Volumetric Flow Rate and Coolant Pressure
for T-15 HSS and Carbide Spade Blades
Note:These flow rates and coolant pressures are general
recommendations for water-based coolants. They are
guidelines for achieving maximum tool life and chip
evacuation at the recommended speeds and feeds.
Technical Data
The table recommends adjusted flow and pressure rates for
blade size, blade material, and holder length (short, medium,
long, extended length). Since carbide blades are normally
used in applications 5 x diameter or less, the long and

Premium Coatings:
• TiN (Titanium Nitride) gives longer tool life and added
lubricity, while allowing more aggressive machining of steels.
• TiCN (Titanium Carbonitride) is a general purpose coating well
suited to machining of mild steel, ductile cast iron and
nonferrous materials such as aluminum and copper alloys. TiCN
is superior in preventing excessive BUE (built-up edge).
• “G” is comprised of more than 20 layers of TiCN and TiAlN
with an overcoat of TiN optimized for drilling mild steel and
ductile cast iron.
• TiAlN (Titanium Aluminum Nitride) a multilayer, mixed phase
coating designed for high-speed machining in alloy steels, high
temp alloys, gray cast iron and titanium. Performance advan-
tages require TiALN coated tools to be operated at relatively high
speeds, typically 50% greater than other PVD coatings such as
TiN.
• CX-H is a proprietary coating designed for optimal drilling of
abrasive, short chipping nonferrous alloys (e.g. red brass, Al-Si
alloys).
• Diamond coating is designed for abrasive nonferrous alloys.

Technical Data: Carbide Blades
Premium Coatings:
• TiN (Titanium Nitride) gives longer tool life and added
lubricity, while allowing more aggressive machining of steels.
• TiCN (Titanium Carbonitride) is a general purpose coating well
suited to machining of mild steel, ductile cast iron and
nonferrous materials such as aluminum and copper alloys. TiCN
is superior in preventing excessive BUE (built-up edge).
• “G” is comprised of more than 20 layers of TiCN and TiAlN
with an overcoat of TiN optimized for drilling mild steel and
ductile cast iron.
• TiAlN (Titanium Aluminum Nitride) a multilayer, mixed phase
coating designed for high-speed machining in alloy steels, high
temp alloys, gray cast iron and titanium. Performance advan-
tages require TiALN coated tools to be operated at relatively high
speeds, typically 50% greater than other PVD coatings such as
TiN.
• CX-H is a proprietary coating designed for optimal drilling of
abrasive, short chipping nonferrous alloys (e.g. red brass, Al-Si
alloys).
• Diamond coating is designed for abrasive nonferrous alloys.

Application Information
Application Guidelines
Concentricity
On live spindle applications such as boring mills and machining
centers, it is necessary to have a rigid and true running spindle.
Spindle runout must be no more than .004" TIR.
On turning machine applications, it is necessary that the drill be
on center or concentric with the spindle centerline within .004"
TIR. Angularity must not exceed .003" in 6". Both of these
conditions are easily checked with an indicator magnetically
mounted on the face of the spindle. Another way to check
concentricity is to drill a hole and measure size. Then rotate the
drill 180°, drill a hole, and measure size. One quarter of the
difference between the two hole sizes is the distance the drill is
off center.
Starting Feed Rate
In some extremely tough materials, it may be advisable to reduce
the feed to about 30% per revolution until the full diameter of the
drill is in the cut. The same procedure may be necessary when
using extra length drills.
Coolant
In steel cutting applications, coolant should be fed through the
tool to insure maximum cooling at the cutting edge and to flush
chips out of the hole. Shallow holes may be drilled in steel with
a well-directed flow of flood coolant. Cast iron can be run dry or
with flood coolant, but through-the-tool coolant is preferable.
Troubleshooting Guide
Problem Cause Solution

Reamers
Higher Feed Rates, Longer Tool Life
METCUT
®
reamers are designed to operate at feed rates up to
twice conventional reamer feed rates, resulting in higher pro-
ductivity. And METCUT
®
reamers last longer, which means less
machine downtime due to tool changes, and more production
per tool. The net result is that METCUT
®
reamers provide the
lowest cost per hole.
Surface Finishes of 25 RMS or Better
The use of METCUT
®
reamers can eliminate the need for some
subsequent grinding, honing or burnishing operations by pro-
ducing surface finishes of 25 RMS or better in free-machining
materials. Hole-finishing accuracy and repeatability are un-
matched:
• Roundness accuracy to within 0.0001".
• Hole size accuracy to within 0.0003".
• Straightness accuracy to within 0.0002".
• Higher depth-to-diameter ratios at above tolerances.
• Technical assistance available to achieve 16RMS or better,
and consistently hold hole size to less than .0003"

Sharpening Profile
The profile form on the reamer is impor-
tant in obtaining the best finish and
longest possible tool life.
METCUT offers two basic types of pro-
files with our controlled CNC form type
sharpening methods.
I. The Double Lead Profile for enhanced
surface finish. Following the primary
chamfer, a nose section is blended into
the straight portion. The nose section
removes the feed marks prior to the final
sizing of the hole and provides a 25 to
50 RMS finish.
II. Single Lead Profile for enhanced tool
life where finish is not as critical. This
provides a profile of a chamfer tangent
to the straight portion as shown in the
diagram.

What Makes METCUT Reamers Better?
Custom Sharpened
For Your Application
Our application engineers will select a
sharpening profile best suited to accom-
plish your specific hole finishing and
production objectives. Significant vari-
ables include the material you are ream-
ing, the surface finish you require, and
the tool life you require. Generally, there
is a trade-off between degree of surface
finish and tool life (the finer the finish
required, the shorter the tool life).
METCUT engineers will work to optimize
the variables to best meet your quality,
productivity, and cost objectives.
When ordering, please provide the fol-
lowing information:
• Roundness, size and straightness
tolerances.
• Finish requirement.
• Material to be reamed.
• Stationary or rotating work piece.
• Diameter of bushing (if applicable).
• Floating or fixed tool holder.
• Blind hole clearance.
• Any other special feature of the applica-
tion, such as cross holes, intersection
holes, etc.
Unique Cutting-Edge Geometry Ensures “Free Cutting Action”
A precise combination of positive clearance angles, sharp cutting edges, and
irregularly spaced flutes serves to minimize friction, harmonics, chatter, welts, and
galling – common problems that diminish the life and performance of conventional
reamers.
This unique cutting-edge design is produced on the most sophisticated CNC
production equipment, ensuring that each cutting edge is accurately ground. All of
the reamers produced to a particular set of specifications are virtually identical
providing maximum tool-to-tool repeatability. State-of-the-art electronic gaging
equipment ensures that flute height variation, land width, and clearance angles are
being held to allowable limits.
Designed for Effective Chip Disposal
Coolant-Feed reamers provide maximum chip-flushing action in blind-hole reaming
applications. The coolant is fed through the reamer body; it hits the end of the blind
hole and is forced back through the flutes, flushing the chips from the cutting area
while lubricating and cooling the cutting edges.

Oil Flow in Coolant-Feed Reamer Application
Irregularly-Spaced Flutes
Irregular spacing is a standard feature
of all METCUT oil-feed reamers. This
type of spacing provides a controlled
cutting action that resists chatter and the
formation of “welts.” This flute spacing
design, combined with the oil-feed and
cam-controlled sharpening features al-
lows these reamers to produce surface
finishes which do not require additional
finishing operations. The teeth are
spaced diametrically opposite each
other for easy and accurate inspection.

Reamer Reconditioning & Special Designs
Reamer Reconditioning
All METCUT reamers can be returned for
reconditioning. We offer three basic services,
all of which result in re-establishment of the
original, precisely controlled cutting edge.
For high speed steel, solid carbide, and
carbide-tipped tools that are not badly worn,
a lead sharpening is a very economical way
to regain the fine finish and precise sizing
these tools provide. If the reamer is badly
worn or is undersize, we can resize it to a
smaller diameter within its range; or, for
carbide tipped reamers, we can replace the
carbide and size the reamer to its original
diameter.
A record is kept of the tool size and profile of
each new order so it can be precisely
duplicated on any recondition order.
Special Designs
In addition to the standard reamers listed
in this catalog, special designs can be
furnished while still utilizing our special
features.
Upon inquiry and/or submission of part
data, our engineering department will
quote your special application, whether it
be a “stub” type reamer, extra length
shank, taper design, or larger diameter
than offered within our stock line.
Inserted blade reamers are also available
by special order, as are multi-diameter,
front-piloted, rear-piloted and jig bore
styles.

Counterbores Application Information
Counterboring—Surface Feet Per Minute (SFPM)
The table below lists starting SFPM rates for certain materials using carbide
or high speed steel cutters. These speeds are starting recommendations
only. There are many variables, such as machine and spindle condition,
available power, fixturing, tool holding, spindle deflection, tooling and produc-
tion expectations, etc. Some adjustments may be required for your specific
operation. METCUT’s experienced sales engineers will be happy to help you
attain the highest efficiency possible in your application.
Since counterboring is often a secondary operation, it is sometimes per-
formed on machines that are quite worn, with excessive run-out and
insufficient power. When trouble is encountered, the condition of the ma-
chine, as well as the cutter, should be considered.
Converting SFPM to Revolutions Per Minute (RPM): RPM =
3.82 x SFPM

Port Contour Cutters
A Full Range of Porting Tools for SAE, ISO,
BSPP/BSPF & NASA Specifications
METCUT Port Contour Cutters produce the form and finish
required on internal straight thread o-ring ports in a single
operation. Straight thread ports usually are required for high-
pressure hydraulic fittings, which must be in compliance with
automotive, military, aerospace and commercial specifica-
tions.
METCUT porting tools are form-relief ground and designed so
that a simple face grinding reconditions the tool with no
dimensional loss.
METCUT produces the most complete line of Port Contour
Cutters in the industry. High speed steel and carbide tipped are
standard in all sizes. Straight, morse taper and radial drive
shank styles are available on all size tools. Indexable porting
tools are available for meeting SAE and military specifications.

Metalcutting Safety
IMPORTANT SAFETY INSTRUCTIONS
Read before using the tools in this catalog!
Projectile and Fragmentation Hazards
Modern metalcutting operations involve high spindle and cutter speeds and high temperatures and cutting forces. Hot metal chips
may fly off the workpiece during metalcutting. Although cutting tools are designed and manufactured to withstand high cutting forces
and temperatures, they can sometimes fragment, particularly if they are subjected to over-stress, severe impact, or other abuse.
To avoid injury:
• Always wear appropriate personal protective equipment, including safety goggles, when operating metalcutting machines
or working nearby.
• Always make sure all machine guards are in place.
Breathing and Skin Contact Hazards:
Grinding carbide or other advanced cutting tool materials produce dust or mist containing metallic particles. Breathing this dust
or mist — especially over an extended period — can cause temporary or permanent lung disease or make existing medical conditions
worse. Contact with this dust or mist can irritate eyes, skin, and mucous membranes and may make existing skin conditions worse.
To avoid injury:
• Always wear breathing protection and safety goggles when grinding.
• Provide ventilation control and collect and properly dispose of dust, mist, or sludge from grinding.
• Avoid skin contact with dust or mist.
For more information, read the applicable Material Safety Data Sheet provided by Kennametal and consult General Industry Safety
and Health Regulations, Part 1910, Title 29 of the Code of Federal Regulations.
These safety instructions are general guidelines. Many variables affect machining operations. It is impossible to cover every specific
