Feature
▶Due to new coating and new tool geometry, outstanding cutting ability and wear resistance.
▶Due to unique ball nose geometry and cutting edges, cutting force decreased, and wear resistance increased.
▶Excellent performance when cutting prehardened steels, up to HRc55 which are used for molds & dies.
High Speed Cutting for Pre-Hardened Steels up to HRc55 -4G MILLS
Suitable for a wide range of work material, specifically for increasing tool life when machining pre-hardened materials, low hardness materials, cast iron, etc. High speed cutting, dry and wet cut recommended together.
