Abstract
In order to reliably shape and remove the cut chip under different cutting conditions a polygonal cutting bit is proposed for cutting tools having raised chip forming elements wherein the chip forming elements are given essentially the shape of a pyramid frustum. Advantageously the pyramid frustum forming the chip forming element has a triangular shape with concavely extending side faces and/or rounded corners. The chip forming elements are possibly disposed in chip forming grooves which again are of a concave or stepped design and are at least in part face ground and no higher than the cover face of the cutting bit.
