- Features List
- ✅【M35 Cobalt Superhard High Speed Steel】: ISI M35/1.3243/SKH55/M35 steel is a kind of high speed steel containing cobalt, which has the characteristics of high wear resistance, high pressure resistance and sintering resistance.
- ✅【Four groove step drill】: The ordinary step drill is easy to flex during the cutting process, but the four groove step drill is more stable in the cutting. The service life is twice that of ordinary ladder drills, the drilling accuracy is significantly improved, the cutting speed is faster when drilling, and it has a unique effect on stainless steel drilling.
