Abstract
A cutting insert for a machining cutting tool. In a radial direction Q, which extends in a main plane H from the cutting corner to a center Z of the cutting insert, the following are formed in order: a falling cutting surface, a chip guiding stage base adjacent the cutting surface, a first chip guiding stage, which is adjacent to the chip guiding stage base and has a first surface rising from the chip guiding stage base and a first plateau adjacent thereto. A second chip guiding stage has a second surface rising from the first plateau and a second plateau adjacent thereto. A third chip guiding stage has a third surface rising from the second plateau and a third plateau adjacent thereto.
