Abstract
A coated cutting tool has a substrate and a coating. The coating includes at least one multi-nano-layer having a nano-composite nano-layer formed of crystalline (TiAlCr)N and amorphous SiN, wherein 0.25≦x≦0.75, 0.25≦y≦0.75, 0.05≦z≦0.2, 0.85≦x+y+z≦0.97. The atomic ratio of silicon is 1−x−y−z and 1−x−z<0.75 and the thickness of the nano-composite nano-layer is from 1 nm to 100 nm.
