Left-Hand Flute
The left-hand spiral is
designed especially for
through hole reaming. Due
to this design, the chips
are being pushed forward
immediately after formation.
Straight Flute
The coolant flow assists the
chip evacuation process. It
directs the just-formed chips
backwards. The chips pass
through the straight flutes and
are thrown out of the hole,
without causing any damage
to the reamer or hole surface.

ATTENTION: Cutting tools can break during use.
To avoid injury always use safety precautions
such as gloves, shields and eye protection.
Assembly Instructions (BN5-BN9)
First Assembly
• Clean the toolholder pocket (Fig. 1)
• Clean the reamer head clamping cone
• Insert the clamping screw into the holder and rotate
it 2-3 turns in a clockwise direction (Fig. 2)
• Clamp the reaming head on the screw; note, BN8
and BN9 can be assembled only in a specific
position relative to the screw (rotate the head
until locating the correct position) (Fig. 3)
• Manually rotate the reaming head until
it sits firmly in the pocket
• Tighten with the special key (Fig. 4)
• Make sure there is no face gap between the
toolholder and the reaming head (Fig. 5)
Indexing
• Release the reaming head with the key, turning in a
counterclockwise direction until it rotates freely
• Rotate another one turn by hand
• Remove the reamer head from the tool; the
clamping screw should remain inside!!!
• Clean the pocket of the toolholder (Fig. 1)
• Clean the cone on the new reamer head
• Clamp the reaming head on the screw; note,
BN8 and BN9 can be assembled only in a
specific position relative to the screw (rotate the
head until locating the correct position) (Fig. 3)
• Manually rotate the reaming head. In the beginning it
should rotate without the screw and then (after 1/6 of
a turn) it should engage with the screw. Rotate until it
sits firmly in the pocket. If the screw rotates together
with the reaming head from the beginning, remove the
reaming head and open the screw another one turn.
• Tighten with the special key (Fig. 4)
• Make sure that there is no face gap between
the toolholder and the reaming head (Fig. 5)

When choosing a reamer, it is important to select a lead geometry that
covers the reaming allowance.
Reaming Allowance
Reaming allowance is the stock material which should
be removed by reaming. It is recommended to leave
different reaming allowances depending on the workpiece
material and the pre-hole quality. Pre-hole should be
smooth and straight, without deep scratches on it.
Complementary Grades (on request):
IC30N cermet tipped, recommended for reaming
the following materials: non-alloyed (mild) steel, low
alloyed steel (<5% of alloying elements), free cutting
steel, tempered steel (tensile strength <1100 N/mm2)
and nodular iron (GGG40, GGG60, etc.) ID5 (PCD)
recommended for high speed reaming of aluminum (special
cases). RN01 (DLC coating) recommended for reaming
the following materials: aluminum alloys (cast, wrought,
etc.), brass, bronze and other nonferrous materials.

* Standard edge geometries are not suitable for reaming titanium and high temperature alloys. In order to choose a proper geometry, please ask for our recommendations.
• The given cutting data recommendations refer to the short holders (3xD effective reaming overhang). For longer holders, the cutting speed should be reduced proportionally.
• For relatively large leading angles (spot-facing geometries), the feed should be reduced up to 30%.
• All the given cutting data recommendations refer to the machines with spindle through coolant supply.

USER GUIDE
REAMERS
Cutting Speed
The cutting speed has the highest influence on the
surface quality of the reamed hole and on the life of the
tool. Increasing the cutting speed beyond the optimum
speed will cause increased tool wear due to the increased
cutting temperature. The increased speed also causes
an increase in the built-up edge (material that is welded
to the cutting edge). The built-up edge damages the
surface finish and shortens the life of the tool. In order
to achieve high surface quality and longer tool life, the
cutting speed for reaming should be kept relatively low.
Feed Rate
The feed rate directly influences the wear on the cutting
edge. As the feed rate is increased, the cutting forces
increase almost proportionally. The feed, however,
has less influence on the machined surface quality
and tool wear than the cutting speed (i.e. the feed
can be varied in a relatively wide range without having
material influence the quality of the machined hole and
the respective tool life). It is therefore recommended
to select the highest possible feed in order to shorten
reaming times without significantly reducing the tool life.
Reaming Allowance
The reaming allowance (the amount of material to be
reamed) also influences the tool life. In order to achieve
high tool life, the reaming allowance should be kept
at a reasonable minimum considering the process to
be performed. If the reaming allowance is too small, it
may result in a high dimensional variation (inability to
maintain the required tolerances) and a decrease in the
machined surface quality. When reaming materials that
have surface defects or have been welded or flame
cut, the reaming allowance should be increased so
these factors do not appear on the reamed surface.
Coolant/Lubrication
The high degree of friction between the tool and the
wall being reamed demands the use of a fluid for
lubrication and cooling. Using lubrication is more
critical for maintaining tolerances than using a coolant.
General cutting oils and emulsions may be used. It
should be noted that in some cases emulsions will yield
a better surface finish than cutting oils. Emulsions are
thinner fluids that are able to reach and more uniformly
lubricate the cutting edges better than viscous cutting
oils (especially when performing deep applications).
In order to determine the most suitable lubricant
for a particular application, tests should be run on
the material to be cut, on a case-to-case basis.
Reaming Prerequisites
In order to achieve high tolerances for
reaming applications, there are certain
requirements that must be considered.
1 Condition of the tool - If the tool is reground, both an exact
concentricity and high quality grinding are indispensable.
2 Workpiece material - Axis shifting and warping (i.e.
incorrect hole positioning) can only be corrected to a
certain degree when reaming. A critical factor is the
initial opening in the workpiece. This opening must be
even, or if the prepared hole is countersunk, a cone
countersink must be used. Failure to properly prepare
the initial opening can result in irregular countersinking
that leads to the reamer being pushed out of its
proper alignment. Ideally, pre-machining should be
performed in a chuck to avoid alignment defects.
3 Through holes - For best results, the holes to be reamed
should extend completely through the workpiece
material. This allows for easy exit of both the cutting
fluid and the reamed material. Negative flute reamers
are advantageous in through hole reaming.
4 Blind holes - Use straight flute reamers for blind holes.

The INDEXH-REAM standard line covers reaming
applications of 8-32 mm hole diameters. The indexable
cutting insert has two cutting corners with 4 lead
angle options and 3 rake angle variations, covering
most workpiece material types. The INDEXH-REAM
single indexable insert with carbide pads provides
a combination of economical and high precision
results on a very wide range of materials.
Important
Lead type of the tool (pads) should be compatible
with the lead type of the insert. Using an improper
insert will damage the tool and the reamed part.
Guiding Pad Line
The guiding pads are precisely ground for a specific
diameter, and therefore, can only be used for reaming
on appropriate hole sizes. The adjustment mechanism
is designed for a specific diameter setting and for wear
compensation (a few microns only). The same tool
can not be used for reaming different diameters.

IC07 grade is the basic substrate for reaming inserts.
It is a very versatile submicron grade. IC07 features
very high fracture toughness and wear resistance,
which is required for efficient high speed reaming.
An uncoated IC07 can be used for machining
nonferrous (N type material group) applications.
Two types of standard coatings are available:
• IC907 – a TiAlN PVD coating for steel (P) and
stainless steel (M) workpiece material groups
• IC507 - a TiCN+TiN PVD coating for cast iron (K)
workpiece material group.
The following grades can be provided on request:
• PCD grade for machining aluminum
• PCBN grade for machining cast iron
• IC30N (cermet) for machining steel

Insert Holder
Applications
Through Hole Blind Hole
Through Hole
Short Flute Holder. This
holder has a lateral coolant
outlet located right above
the insert. The coolant is
pointed directly to the cutting
edge to lubricate it and
divert the chips forward.
Additional coolant outlets
are located behind the
guiding pads. Their purpose
is to reduce high friction
that is created between
the pads and the reamed
surface during machining.
Blind Hole
Long Flute Holder. This
holder has a frontal coolant
outlet. The liquid reaches the
bottom of the blind hole and
evacuates the formed chips.
These chips are conveyed
backwards through the long
chip gullet (flute) of the holder.

Setting Procedure
1Place the reamer between the centering pins of the device.
2Use the pad as a reference for setting the indicator to zero.
3Rotate and place the inserts against indicators.
4Tighten the adjustment screws in a clockwise direction.
5Adjust the frontal side of the insert to:
+15 µm (+0.6 µin) on D≤9.99,
+20 µm (+0.8 µin) on D≤10.00
6Adjust the rear side of insert to:
+5 µm (+0.2 µin) on D≤9.99,
+10 µm (+0.4 µin) on D≤10.00
Back Taper
The back taper prevents the reamer from jamming, as
well as lowering reaming forces and improving surface
quality. Incorrect back taper may cause unstable
reaming, accelerated wear and rough surface finish.
High Friction Lubricated Zones
Insert Indexing
1Rotate the adjustment screws one turn
counterclockwise (CCW).
2Rotate the clamping screw CCW from the
top and/or clockwise (CW) from the bottom,

Setting Methods
There are two optional setting methods - comparison
micrometer and setting device. Comparison micrometer
with dial gauge, although a low cost solution and readily
available for small workshops, is prone to damaging
the cutting edge and therefore not recommended.
Using a Comparison Micrometer
Set the micrometer to the correct diameter using the
precision blocks. Adjust the frontal diameter and back
taper by turning the adjustment screw clockwise.
The frontal diameter should be larger than the rear
diameter by approximately 0.015 mm.(0.6 µin).
Using a Setting Device
ISCAR’s mechanical setting device enables easy,
quick and accurate adjustment. Due to its modular
construction, it can be used for standard, special
and more complicated reamer adjustments.
Setting Device Located Between Centers
• Shorter setting time
• Modular system
• Higher accuracy
• No risk of damaging the cutting edge

Tap Surface Treatments and Coating Types
The high speed steels we use grant high wear resistance
and toughness. For machining certain materials,
various surface treatments are an advantage.
Steam Tempered (ST)
The steam tempered is a Fe3O4 oxide coating
which reduces the friction between the tool
and workpiece and prevents cold welding.
Nitriding (NI)
Recommended surface treatment for machining hard
wear/abrasive materials such as grey cast iron, aluminum
alloys with high silicon percentage (more than 10%).
TiN Coating (TI)
The TiN coating has a hardness of approximately
2,300 HV and is temperature resistant up to
approximately 600°C. This is an excellent golden
colored coating for general applications.
TiCN-COATING – TiCN
TiCN takes place of TiN when the conditions require the
coating to have a different hardness and toughness.
The TiCN brings an advantage to machining very difficult
steels or cutting interrupted bores. The TiCN-coating
has a hardness of approx. 3,000 HV, but is temperature
resistant up to approx. 400° only. That means TiCN
needs excellent cooling for long service life. Color:
Blue-grey coefficient of friction against steel : 0.4
TiAIN-COATING – TiAIN
This is a special coating for machining abrasive materials
such as: grey cast iron, alu-alloys with silicon, fiber
reinforced plastics, etc., or machining under high
temperatures, which means with insufficient cooling, or
high speeds ≥ 600m/min. TiAIN has a hardness of approx.
3,000 HV and is temperature resistant up to approx. 800°.
Color: Violet-grey coefficient of friction against steel : 0.4
Hardslick-COATING – Hardslick
Hardslick combines in a novel way the advantages
of an extremely hard, thermally stable TiAIN-coating
with the sliding and lubricating properties of an outer
WC/C (Tungsten carbide/carbon) coating. The hardslick
coating has a hardness of approx. 3,000 HV and
is temperature-resistant up to approx. 800°. Color:
Violet-grey coefficient of friction against steel : 0.2
Tolerances According to DIN EN 22857
For taps with ISO metric threads.
The following chart gives a comparison between
the new standard DIN EN 22857 and the withdrawn
standard DIN 802 part 1. An important change is the
re-classification from tap tolerance to tap application class.
Application

taps to DIN

Class 2 ISO 2 6H 5G 5G 6H - -
Class 3 ISO 3 6G - - 6G 7H 8H
- - 7G - - - 7G 8G
A suitable transition period is to be expected.
Codes for tolerance classes 7G/8G and <X> tolerance
zones have yet to be standardized within DIN EN 22857,
and the values from DIN 802 part will remain valid.

For Optimum Tapping Conditions, Reduced
Machining Times and Increased Tap Life
Selection of the Most Suitable Tap
As a general rule, materials with deformation
capability of at least 10% can be cold-formed. To
decide on the most suitable tap, please refer to
the tap recommendation table on page 346.
Pre-Tapping Holes
Check that the holes are within the prescribed
size range depending on the application (see table on
page 364) The holes should be clean and swarf-free.
Lubrication
Frequently the lubricant content of the coolant used
for general machining is too low for tapping.
• If it is not possible to increase the lubricant
content, following are some possible solutions:
• A separate Iubricating unit can be connected
to the machine control to deliver the required
quantity of concentrated emulsion into the core
hole or onto the tap.Tapping in separate operations
allows the use of the ideal tapping lubricant.
Tapping Speeds
The tapping speed has a great influence on chip flow
and the life of the tap. It is worthwhile to establish the
ideal speed by tapping trials. For recommended initial
values, see table on page 346. In addition, the following
should be taken into consideration: characteristics
of the material, machine and clamping method.
Effects of Unsuitable Tapping Speed
• forced tapping
• tap lead chipping caused by overloaded cutting tooth
• torn threads
• unsatisfactory tap life
• rejected threads
373
USER GUIDE
TAPS
Chip Explusion
Tap selection is also influenced by the type of hole
being threaded. Through hole tapping usually requires
a tap that pushes the chips out in front of the cutting
edge and through the other end of the hole. A bottom
hole tap must pull chips up and out of the hole.
Tap Jamming
Some possible causes of tap jamming are:
• unsuitable tap
• tap with incorrect cutting geometry
• unsuitable coolant for material
• insufficient coolant
• axial pressure (pull or push) on the tap
• core hole too small
• breaks in walls of core hole
• speed too high or too low
• swarf trapped in the hole
• incorrect alignment of tap and core hole
• tap eccentricity
Results of Tap Jamming
• torn threads
• short tap life
• rejected threads
• tap breakage
• scrap workpieces
Tap Mounting
The tap must be mounted on the axis of the core hole.
On non-synchronized machines (feed/speed) we
recommend using a tapping spindle. (ISCAR GTI, GTIN
collets, see pages 381-382)
Tapping Heads
As a rule, with non-synchronized machine spindles
(feed/ speed), the feed rate should be programmed
approximately 5-10% lower than the thread pitch. In
these cases, a tapping chuck must be used which will
compensate the difference between the feed rate and
the thread pitch. It is important that the tension spring
in the axial compensation is set to a minimum pressure
to avoid axially loading the tap. The compression
spring should be tensioned so the tap starts to cut
by compressing the spring up to one-half pitch.
Important
Verify that the correct speed has been selected.
Ensure that ample lubricating coolant is being
used. Machine and equipment stability are
essential for optimal performance and results.
Forming Taps
Forming taps (roll forming or cold forming) produce
threads by deforming the material near the hole walls
rather than by cutting the material. This method often
works well in ductile materials. However, in brittle
materials it often results in unsatisfactory threads.
Torque requirements for forming taps are considerably
higher than for cutting taps. When forming taps
are used, chuck capacity must be decreased by
25%. Forming taps do not produce chips.

Regrinding
Regrinding
Tap regrinding takes place in two steps:
1 regrinding of relieved chamfer
2 regrinding of flutes (see picture 1)
Regrinding of Relieved Chamfer
It is recommended that the resharpening be executed
either on specific tap regrinding machines or on
conventional resharpening machines equipped with an
auxiliary device to generate the circular back relief.
Picture 2 shows regrinding done with the cylindrical
surface of a grinding wheel. Before regrinding, verify
that the tap, fixed between points or on the pincer, runs
concentrical. Also ensure that angle B is in the correct
order to keep the same number of threads on chamfer.
Resharpening of Flutes
The rake angle g is obtained by moving the tap axis, in
relation to the regrinding surface, of an amount X to be
calculated with the formula: X = 1/2 d1 sin (ϒ)
(see picture 3).
(d1 =tap major diameter)

Tap 10 X 1,5 to cut on steel
strength = 600 N/mm2
d1 = 10 mm ; ϒ = 15° ;
sin (ϒ) = 0,25882;
X = 0.25885
2 x10 ; X=1.29 mm
On all taps with spiral flutes, it is possible to find the pitch
of the spiral in reference to the lead screw necessary
for resharpening. In case of using taps equipped with
a deburring tool, it is necessary to extend the flutes
according to the supplier’s recommendation. As the wear
on a tap is mainly on the chamfer area, for taps with a gun
nose, regrinding the flutes can be done on the front area
only (see picture 4).
In cases where the thread flanks are worn (in addition
to the active edges), regrinding as described above is
impractical. In this case restoration is done, by cutting
the chamfer away (thus creating a shorter tap) and then
reproducing the chamfer with same angle and relief.
(see picture 5)
In the absence of special regrinding machines,
such restoration is advisable for regrinding taps
with spiral flutes. This is because regrinding
the flutes becomes unnecessary.

General Recommendations (Regrinding)
Maintenance
It is important to periodically regrind the worn tap. This
is to avoid permanent damage or even tool breakage.
The Grinding Wheels
The structure and grain of grinding wheels must
be appropriate for the tap to be resharpened.
Taps for Cast Iron
Taps used on cast iron can rarely be resharpened, as
it is very abrasive and tends to wear the flank in such
a way that it becomes grossly out of tolerance.
Taps for Aluminun
After regrinding it is advisable to remove
the steel burrs with a wire brush.
Tap Inspection
It is important to inspect the tap after regrinding
to ensure that all of the dimensions and angles
have remained according to its specifications.
Controls (tests)
Once the tap is resharpened, it is always
best to test it to correctly obtain the same
threads as when the tap was new.
• The chamfer must be perfectly on axis
in order to avoid the effects of picture 6.
The cutters must have correct divisions.
• The results of resharpening with an incorrect
division is shown in picture 7.
• The length and number of threads in chamfer must
be precisely identical to those of the new tap.
