Technical Examples

The invention concerns a wear-resistant coating on rotary metal-cutting tools such as drill bits, countersinks, milling cutters, screw taps, reamers, etc. The coating according to the invention consists essentially of nitrides of Cr, Ti and Al with a unusually high share of Cr atoms, namely 30 to 60% referred to the totality of metal atoms. In multilayer coatings and even more in coatings made of homogeneous mixed phases, this high Cr share results in particularly large tool life distances for the tools hardened with these coatings. These tools exhibit their superiority particularly during dry use without cooling lubricants or with minimal lubrication.
