Abstract
Provided is a coated cutting tool, comprising: a substrate; and a coating layer formed on at least part of a surface of the substrate. The coating layer includes at least one composite nitride layer including a compound having a composition represented by (TiAl)N [x denotes an atomic ratio of a Ti element based on a total of the Ti element and an Al element, y denotes an atomic ratio of the Al element based on a total of the Ti element and the Al element, and 0.10≤x≤0.50, 0.50≤y≤0.90, and x+y=1 are satisfied]. The composite nitride layer includes a phase having a lattice constant of from 0.400 nm or more to 0.430 nm or less, and a phase having a lattice constant of from 0.755 nm or more to 0.810 nm or less.
