Chipbreaker Appearance Features Chipbreaker Appearance Features
The sharp cutting edge and raised 3-dimensional chipbreaker designed to
projection near corner contribute to have excellent chip control capability and
01 excellent chip control at very small depth PS low cutting force in finishing to medium
cutting. Low cost, M-class positive insert
of cut and low feed. used for high efficiency boring in a wide
range of applications.
Developed chipbreaker for finishing at low Developed chipbreaker for medium
cutting depths. Optimal chip control due cutting. Excellent chip control due to wide,
PSF to pre-positioned chipbreaker element. PM positive chip flow zone.
3-dimensional chipbreaker designed to
have excellent chip control capability and
PSS low cutting force in finishing to medium
