            For rough copying. It is available for roughing and semi nishing, but especially suitable for rough copying of mold. Shank diameter is

            larger than the cutting diameter and it is highly rigid. Due to the strong cutting edge with large at surface, it is suitable for hardened

L materials and titanium alloy. It can provide the good surface roughness of 2.5 to 4.9Ra (m).
