The small groove width design meets the chip breaking requirements in the field of small depth of cut.
Large rake angle design reduces cutting resistance and obtains excellent processed surface quality
BF–finishing
Special design of chip breaker promotes chip curling and facilitates chip removal
Small rake angle design, high tip strength and strong versatility
AK– semi-finishing
The sharp edge design meets the requirements of surface machining.
Edge inclination design, control cutting chip direction, reduce cutting resistance.。
BK– semi-finishing
Large groove width design, enhance chip removal and achieve stable machining. Inclination angle design to control chip flow direction and reduce cutting resistance force.
MM–roughing
Double front angle design, taking into account sharpness and strength, wide processing range.
Hyperboloid chip breaker design promotes stable chip rolling and breaking Chips, dramatically improve chip removal.
