Abstract
The present coated cutting tool includes a substrate with a coating including a layer of TiAlCrSiN, where x is 0.30-0.50, y is 0.25-0.45, z is 0.05-0.15, and v is 0.10-0.20, x+y+z+v=1. The layer has a cubic phase with a distribution of unit cell lengths within the range 3.96 to 4.22 Å for the cubic cell. The unit cell length range 3.96 to 4.22 Å includes more than one intensity maximum in an averaged radial intensity profile of an electron diffraction pattern.
