ABSTRACT:
A metal cutting insert is made by sintering an insert body and coating the sintered insert body with a conventional coating. Subsequently, a supporting surface of the insert is ground smooth while removing the coating therefrom. The supporting surface of the insert is thereby formed by an uncoated, smoothly ground surface of the sintered body.
