1、MF：Special chip breaker design to keep both sharp cutting edge and increased blade intensity which can efficiently solve break chip,high cutting temperature,sticking,work hardening and other machining problem.its working efficiency is better than -MSF

2、MSF：Three-dimension designed with double rake angle,it has sharp cutting edge and lower cutting resistance which can efficiently solve break chip,high cutting temperature,sticking,work hardening and other machining problem.cutting edge inclination which can control chip flow direction and obtains excellent surface quality.

3、OMF：Special designed rake angle and cutting edge inclination for finishing ISO M material,it has sharp cutting edge which can decrease cutting resistance,and efficiently control chip and acquire good surface quality

4、OMM：Special chip breaker design to keep both sharp cutting edge and good impact resistance,which can efficiently avoid accumulated and suited for semi-finishing ISO M material.
