Grades

KCPM20

Coated carbide grade with CVD multilayer (TiN/MT TiCN/Al2O3) and advanced Beyond™ post-coat treatment. Substrate is a well-balanced combination of wear resistance and toughness. It is primarily for light and general machining of steel and stainless steel roughing of cast irons.

Features and benefits

HN geometry is the first choice for high-strength steel and hard machining up to 55 HRC.
