Multiple cutting teeth (8) which are arranged in a row (33, 34) and which comprise cutting edges (9) are formed on the top surface (3). The top surface (3) has opposing regions (31, 32) which slope downward towards the outside from a center (10) and on each of which a row (33, 34) of cutting teeth is arranged. The regions (31, 32) are rotated relative to one another about an axis (X). In this manner, a cutting insert (1) is provided which can be produced in a simple manner and which has a long service life.</p> |
