Abstract
A cutting insert is cooled during chip removing machining of a workpiece by conducting cooling medium through a porous supporting body of the insert. The cooling medium enters the insert through an inlet formed therein at a location remote from a cutting edge of the insert and exits the insert through an outlet formed in the insert at a location proximate the cutting edge. The discharged cooling medium impinges on, and cools, the workpiece.
