Abstract
Provided is a coated cutting tool, which includes a hard coating film containing a layer (c) which is a layered coating film made by alternately layering a nitride or carbonitride layer (c1) that contains, with respect to the total amount of metal elements (including metalloid elements), at least 55 atom % aluminum (Al), chromium (Cr) having the second highest content percentage, and at least silicon (Si), and a nitride or carbonitride layer (c2) that contains, with respect to the total amount of metal elements (including metalloid elements), at least 55 atom % aluminum (Al) and titanium (Ti) having the second highest content, each layer having a thickness of 50 nm or less. A peak intensity Ih ascribable to an hcp (010) plane of AlN in the layer (c) and the total peak intensity Is ascribable to other predetermined crystal phases satisfy a relationship of Ih×100/Is≤15.
