Abstract

A coated cutting tool includes a substrate and a coating. The coating has a (Ti,Al,Si)N layer, which has a periodical change in contents of the elements Ti, Al, and Si, over the thickness of the (Ti,Al,Si)N layer, between a minimum content and a maximum content of each element. The average minimum content of Ti is from 14 to 18 at. % and the average maximum content of Ti is from 18 to 22 at. %. The average minimum content of Al is from 18 to 22 at. % and the average maximum content of Al is from 24 to 28 at. %. The average minimum content of Si is from 0 to 2 at. % and the average maximum content of Si is from 1 to 5 at. %. The remaining content in the (Ti,Al,Si)N layer is a noble gas in an average content of from 0.1 to 5 at. % and the element N.
