1.Blade diameter is from 3mm to 12mm,overall length is from 50mm to 75mm

2.Arc angle blade tip design prevents chipping

3.45°helix angle and high -intensity heat resistance of the layers of use,lower cutting resistance and prolong the tool life.

4.Good surface finish,increased feed rate.

5.HRC 55material is no problem for gerneral cutting,like P20 S45C, SCM SK, FC FCD, CU

  HRC 60 material is super for high speed steel cutting.like SKD, SUS
