  • Patent number: 11965235
    Abstract: Provided is a coated cutting tool, which includes a hard coating film containing a layer (b) formed of a nitride or a carbonitride, a layer (c) which is a layered coating film formed by alternately layering a nitride or carbonitride layer (c1) that contains 55 atom % or more of Al, Cr having a second highest content percentage, and at least B and a nitride or carbonitride layer (c2) that contains 55 atom % or more of Al and Ti having a second highest content percentage, each layer having a film thickness of 50 nm or less. A peak intensity Ih ascribable to a hcp (010) plane of AlN in the layer (c) and the total peak intensity Is ascribable to a plurality of predetermined crystal phases satisfy a relationship of Ih×100/Is?15.
