Abstract
A coated cutting tool includes a substrate with a coating including a (Ti,Al)N layer having an overall composition (TiAl)N, 0.34≤x≤0.65. The (Ti,Al)N layer contains columnar (Ti,Al)N grains with an average grain size of from 10 to 100 nm. The (Ti,Al)N layer also includes lattice planes of a cubic crystal structure. The (Ti,Al)N layer shows a pattern in electron diffraction analysis, wherein there is a diffraction signal existing, which is shown as a peak (P) in an averaged radial intensity distribution profile having its maximum within a scattering vector range of from 3.2 to 4.0 nm, the full width half maximum (FWHM) of the peak (P) being from 0.8 to 2.0 nm.
