Product Highlights
New SK chipbreaker for finishing to medium cutting
● 10mm square type shank available
● Corner R (rε) = 0.2mm type available
for GK chipbreaker for medium to rough cutting
●
Double-sided design allows both edges
to be used. Compared to the positive
type, the double-sided design offers less
cost per edge and more stability.

■Features of SK Chipbreaker
Optimum chipbreaker design
for finishing to middle cutting
Periphery ground finish
High quality G class periphery grinding.
Suitable geometry for smooth chip control
Sharp Edge
Molded chipbreaker with sharp edge.
Lowering cutting force and deformation by sharp edge
Holder can be placed in multiple
tool post locations
The oversized head of the conventional toolholders for negative
inserts can possibly interfere with the sub spindle.

Against competitor A (DCMT type), the CNMU with
the GK chipbreaker machined the same number
of parts per edge. However because the Kyocera
inserts have double the usable edges, the number of
machined pieces per insert was doubled.
Against competitor B (DCGT type) PR1025's tool
life is improved 1.5 times per edge and 3 times per
insert.
