The cutting element is designed in a cube shape with its upper surface (22) and its lower surface surrounded by an elevated border. The lateral border sections, serving as the cutting edges (26, 27a, 28a, 29), are exceeded in height by the corner areas (32, 34a), which can be flattened at the outer surface. Several raised areas (42, 43, 44, 45) can be integrated in the upper surface and the lower surface of the central area (22), as well as grooves, parallel positioned along the surfaces of the border segments (26, 27a, 28a, 29). |
