Reduces chip control problems
The GF type chipbreaker is added to the current wide
Chip control with point contact
selection of chipbreakers to improve chip control under various conditions.
Reduces chattering during cutting
Ideal for machining using low-powered equipment
such as small lathes
Reduces adhesion to tools and achieves long tool
life in machining of stainless steel, etc.
Achieves excellent chip control and reduced cutting resistance due
to the sharp cutting edge design with a 30° rake angle as well as
the reduction of frictional resistance through chip control with point
contact.
Sharp cutting edge design
with a 30° rake angle
Minimum Groove Width: 1,25mm

Min. Diameter
Select a holder so that the outer diameter of the first groove to
be machined comes within the range of maximum and minimum grooving diameter of the holder.
If the first groove meets the range of the effective grooving
diameter during groove expansion, the grooving diameter will
not be limited for the second and later passes.
Precautions for Turning

Considering the rigidity of the holder, we recommend machining from the outside to the inside.

Cutting Point
Cutting Point
Principal Force
If machining is performed
toward the outside, the wall
thickness remaining on the
principal force side will become thinner, which reduces
the rigidity of the holder.
Principal Force
- If the first groove meets the range of the effective grooving diameter in face turning, the grooving diameter will not be limited for the
second and later passes.
- Select the chipbreaker of the lower limit side of the recommended cutting conditions and straight chips before evacuation.
(In face grooving, broken chips easily get stuck in grooves, which causes problems.)
- When breaking chips, step feed is required.
Key Points for Internal Machining
Recommended Chipbreaker:
ML, GL
Precautions for Internal Machining
If the prepared hole diameter is small, use an ML or GL low-feed chipbreaker, each of which reduces chip curl diameter, to ensure adequate
chip evacuation.

Remove any foreign particles or oil from the insert seat before attaching the insert.
Ensure the seat location is clean and free of damage.
Slide the insert level over its seat.
Push the insert with its opposite end (the holder side) firmly against the insert stop end.
The recommended tightening torque is 5N.m. Tightening above the recommended torque may damage
the insert or the holder which could cause injury and other accidents.

Remove any foreign particles or oil from the tool post before attaching the holder.
Ensure the seat location is clean and free of damage.
Attach the holder so that the insert is perpendicular to the workpiece.
Set holder with shortest possible overhang.
When grooving or turning, adjust the center height of the cutting edge to as close ±0mm as possible.
(Within ±0,1mm is recommended)
Incorrect center height adjustment may cause chattering. In cut-off applications, adjust the center height
of the cutting edge to a value from 0,0 to +0,2mm).
A lower center height will result in larger nip at the center.
