COATED CUTTING TOOL

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 (TixAlyCrz)N and amorphous Si3N4, 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...
