采用短刃加避空设计，大幅提升刀具耐磨性，同时可获得更高要求工件表面质量.
主要针对HRC45~70的淬硬钢材加工，特别适用于需长时间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.
