Abstract
A coated cutting tool including a substrate and a coating is provided. The coating includes a nano-multilayer of alternating layers of a first nanolayer being TiAlN, 0.35≤x≤0.70, and a second nanolayer being TiAlN, 0.12≤y≤0.25. A sequence of one first nanolayer and one second nanolayer forms a layer period. The average layer period thickness in the nano-multilayer is ≤7 nm. The nanomultilayer has a columnar structure with an average column width of ≤70 nm.
