Abstract

A round cutting insert, normally made of cemented carbide, for turning operations is provided. It comprises a top surface, a round clearance surface, and a bottom surface. The top surface comprises a number of main, circumferentially spaced chip-breaking grooves. Essential for the invention is that each of the main grooves comprises a further chip-breaking groove which is encircled by the main groove. Thanks to the superposed grooves, the insert becomes very versatile, with good chip control both at low and high feeds, as well as at small and large cutting depths.
