INDEXABLE
COUNTERBORING HEAD
Single Tube System
Double Tube System
WORLD WIDE BEST SELLER
Has been used around the world for its high quality and ease of use for a quarter-century
Counterboring
Counterboring is used to open up a pre-bored
hole to obtain a more exact diameter. In
some instances where machine power is
limited, a hole can be drilled with a smaller
diameter drill head and counterbored to the
required diameter.
ø85.20mm
Former Indexable Reaming Head was renamed to Indexable Counterboring Head.

Replacing Guide Pads
The guide pad is a consumable item as well as the insert
The guide pad has 2corners.
When the wear comes to 2nd corner, reverse the guide pad.
When the 2nd corner also gets worn, replace the guide pad with a new one.

Diameter Setting
The Drill Head diameter is set and inspected with a master insert in our final inspection. However, the inserts in
the market have a tolerance fluctuation so each time you change or index the insert, the diameter must be
adjusted as per the following method.
When a corner change is made on the insert, it must be adjusted to correct size or a damage
can be caused to the head body or a work piece material.
1
1 The dimensional guide pad must be slid forward to measure the diameter.
1-1 Loosen the lock screw and slide the guide pad forward.
1-2 Retighten the lock screw at the measuring position.
2
2 Measure the diameter with a micrometer.
We recommend setting the tool diameter at h8 tolerance to the cutting diameter.
If the diameter is incorrect, go to below step 3
If it's correct, go to below step 4
3-1
3 Adjust the cartridge
3-1 First loosen the lock screw of the cartridge and then tighten it slightly.
3-2
3-2 Proceed to adjust the diameter, using the 2 adjust screws and measure
with a micrometer.
3-3
3-3 When set to the size, retighten the lock screw.
3-4 Recheck the diameter with a micrometer. If it is still out of tolerance,
repeat the procedure from the step 3-1
Please make sure to tighten the lock screw firmly before using. If loose, the
cartridge may move and cause serious problems during machining.
4
4 Slide the dimensional guide pad back to the original position and tighten the
lock screw.
Please check all the lock screws are firmly tightened as they may come loose
if vibration occurs during drilling.
24
Diameter Setting
Drill diameter is adjusted with an adjust ball for diameter ø25 - ø39.99mm with the following method.
1
1 Slide the dimensional guide pad forward and the retighten the lock
screw at the measuring position.

• Should be applied only when the workpiece and the tool axis are in line.
• Better result is expected for hole straightness and wear-resistance of the
guide bush compared to tool rotating system.
• Keep the alignment between guide bush and spindle within 0.02 mm.
• Can be applied when the workpiece and the tool axis are not in line.
• Keep the alignment between guide bush and spindle within 0.02 mm.
Notes for Setting Up DTS System
Positioning of outer tube and guide bush
Workpiece
Guide Bush
Be sure to set the outer tube into the guide bush by more than 5.00 mm so that the
coolant will be supplied properly
Outer Tube
Positioning of work material and guide bush
Sealing is not required for DTS system because of the vacuum effect, but be sure to keep
the gap between the work material and the guide bush 1.0 mm or less.
At least 5.0mm
Up to 1.0mm
Guide bush size
Guide bush tolerance should be G6 in order
to keep good tool life and cutting accuracy.

Coolant Management
Coolant temperature
The suitable coolant temperature is 30 to 40 °C (90 - 100 °F).
If it exceeds this temperature, the coolant will deteriorate which will cause short tool life and poor surface finish.
Coolant filtration
The coolant must be filtered in order to protect the guide pads and the surface finish.
Using water-soluble coolant
The concentration of water-soluble coolant is recommended to be around 10 % (dilution rate 1/10) in order to protect the guide pads.

Cutting condition and chip form
Chip formation in deep hole drilling
How to decide chip form
Chip formation plays a key role as well as the management of
cutting fluid temperature and volume in STS (Single Tube
System) and DTS (Double Tube System) which enable deep
hole drilling by supplying cutting fluid of large volume and high
pressure. As chips are evacuated through tube with cutting
fluid in deep hole drilling, smooth and steady chip evacuation
can be achieved by proper chip formation.
Generally chip length should be 3 - 4 times width, but it tends
to be longer with difficult-to-cut materials in which case it is
better to make chips thinner (reduce feed) so that smooth
chip evacuation is obtained.
Below picture shows chip formation by cutting speed and
feed. Shorter chips are obtained by reducing cutting speed or
increasing feed.
Chip formation
Chip formation is affected by multiple factors such as work
material, chipbreaker geometry, cutting speed, feed, type of
cutting fluid and cutting fluid temperature. Suitable chip
formation depends on cutting situation but is controllable by
changing the cutting conditions.

Safety Notes
1. Introduction
The following information is provided to be read before using the tool so that the tool is handled properly and safely.
2. Basic Information of Cutting Tool Materials
2-1. Technical Terms
Cutting Tool Material :
General term of tool material, such as Cemented Carbide, Coated Carbide, Cermet, Coated Cermet,
Ceramics, CBN and PCD
Carbide Material :
Cemented Carbide with WC (Tungsten Carbide) as the main ingredient
2-2. Physical Property
Appearance :
Smell :
Hardness :
Specific Gravity :
Depends on materials. (e.g. Gray, Black, Gold, etc.)
None
Carbide and Cermet: 5 - 30GPaHV, Ceramic: 10 - 40GPaHV, CBN: 20 - 50GPaHV,
PCD: 80 - 120GPaHV
Carbide: 9 - 16, Cermet: 5 - 9, Ceramic: 2 - 7, CBN / PCD: 3 - 5, HSS: 7 - 9, Alloy steel: 7 - 9
2-3. Composition
Carbide, Nitride, Carbon-nitride and Oxide with W, Ti, Al, Si, Ta, B, etc. and metals of Co, Ni, Cr, Mo, etc.
3. Notes for Handling Cutting Tool Materials
• These cutting tool materials are very hard but brittle. They may be broken by shock or excessive clamp force.
• Since cutting tool materials have high specific gravities, they can be heavy. Handle with care when transferring and
storing.
• The thermal expansion of cutting tool material is different from that of metal materials. Because of this, for shrink-fit
or cooling-fit products, if the usage temperate is slightly higher (lower) than the specified temperature, cracking may
occur.
• If cutting tool materials become corroded due to cutting fluid, lubricating agents, or other moisture, their strength will
be reduced. Care should be taken regarding storage conditions.
4. Notes for Machining Cutting Tool Materials
• For carbide tool materials, the strength may be slightly reduced due to the surface conditions. For finishing, always
use a diamond grinder.
• When cutting tool materials are ground or heated, dust or mist (smoke) occurs. If a lot of it is inhaled, swallowed, or
comes in contact with the eyes or skin, it could result in injury to the body. When machining, be careful to avoid
exposing your body to the dust or mist; it is recommended that localized ventilation equipment be used and that a
protective mask, protective goggles, and protective gloves be worn. In addition, if the dust, etc. comes in contact
with your hands, wash them thoroughly with soap and water. Do not drink or eat in the work area, and wash your
hands before drinking or eating. Dust on clothes should not be shaken out; use a vacuum, etc. to remove the dust or
wash the clothes in a washing machine. If the cobalt contained in the cutting tool material is touched repeatedly or
over a long period of time, it has been reported that it may affect the skin, respiratory organs, or heart, etc.
• When performing wet machining of carbide tool materials or brazed tool, the cutting fluid may contain heavy metals
and must be disposed of properly.
• When a cutting tool product has been reground, check that there are no cracks after regrinding.
• If a laser or electric pen, etc. is used to mark carbide tool material or products, cracks may form. Do not mark
sections which may be subject to stress.
• When electric discharge machining is used on carbide tool materials or products, cracks may form on the surface
which cause strength reduction. If this process is necessary, make sure to remove the cracks completely by
additional operation such as griding.
• When brazing the carbide tool materials, use the proper temperature to prevent falling off or breaking of the tip.
