High hardness heat treated workpiece (HRC50~63) used for automobile, mold and general industries has features like high hardness, outstanding durability and excellent wear resistance.
Those features occur severe impact on the cutting edge so it makes hard to apply high speed cutting due to frequent chipping and fracture.
The H-Star Endmill improved wear resistance applying ultra-fine substrate and newly developed AlTiSiN coating layer which also ensures stability in cutting from frictional heat. In addition, the optimal cutting edge shape and special treatment on it improve chipping resistance in the beginning of cutting and realize stable cutting.
KORLOY recommends H-Star Endmill which is the optimal tool for high hardness heat treated workpiece machining to improve our customers' productivity.
