采用短刃加避空設計，大幅提升刀具耐磨性，同時可獲得更高要求工件表面質(zhì)量.

主要針對HRC45~70的淬硬鋼材加工，特別適用于需長時間加工的精密模具零件.

The short edge and avoidance design is adopted to greatly improve the wear resistance of the tool, and at the same time, it can obtain higher surface qualityof the workpiece;

Mainly for the processing of HRC45~70 hardened steel, especially suitable for precision mold parts that need to be processed for a long time.
