Abstract

The present invention relates to a method of machining a metal work piece with a coated cutting tool insert having a cemented carbide body and a coating deposited as monolayer(s) or as multiple and/or alternating layers. The coating has a total thickness of from about 25 to about 75 μm and the machining is performed at a cutting speed of greater than about 600 m/min, preferably from about 800 to about 1500 m/min. The invention also relates to a coated cutting tool useful for such machining operation.
