Chipbreaker Appearance Features Chipbreaker Appearance Features
Designed to control the direction of chip 3-dimensional chipbreaker designed to
flow and used for precision finish boring. have excellent chip control capability and
Provides excellent chip evacuation which low cutting force in finishing to medium
Wuu is important to attain a highly accurate PSS cutting. Low cost, M-class positive insert
bore. used for high efficiency boring in a wide
range of applications.
Developed chipbreaker for finishing at low 3-dimensional chipbreaker designed to
cutting depths. Optimal chip control due have excellent chip control capability and
PSF to pre-positioned chipbreaker element. PS low cutting force in finishing to medium
cutting. Low cost, M-class positive insert
used for high efficiency boring in a wide
range of applications.
Developed chipbreaker for medium
cutting. Excellent chip control due to wide,
PM positive chip flow zone.
