Abstract: A cutting insert shapes metallic workpieces by chipping. The cutting insert is especially suited for use in solid drills or double-bit cutters. It has at least one cutting edge which is delimited by a chipping face and a flank extends between two cutting corners. The cutting edge includes two sections which form an obtuse angle and in the area of a roof-shaped tip merge into each other. The chipping face has a raised shaped chipping element which extends from the inside of the chipping face as far as the cutting edge, from where it reaches beyond the roof-shaped tip partially across the two sections of the cutting edge. The cutting edge sections and the adjoining chipping faces include a step delimiting the shaped chipping element, the edges of which step serve as additional cutting edges of the shaped chipping element.
