M42® is a premium cobalt high-speed steel with high hardness and superior hot hardness. The combination of composition and properties allows for machining high-strength and pre-hardened steels, high-hardness alloys, and the difficult-to-machine, nonferrous superalloys.
Titanium nitride (TiN) coating is wear resistant, inert & reduces friction. Used on cutting tools punches etc improving tool life 2-10x over uncoated tools
