M42®

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. This steel exhibits excellent wear resistance and hot hardness with cutting edges on tools remain sharp and hard in heavy-duty and high-production cutting applications.
