Herein a cutting insert (2) and a gear milling cutter is disclosed. A first major side portion (10a) of an insert body (4) of the cutting insert (2) is provided with a first recess (22a) having a first bottom surface (24a) and a second major side portion is provided with a second recess having a second bottom surface. The first and second bottom surfaces (24a, 24b) extend substantially in parallel with a longitudinal axis (6) of the insert body (4). A first minor side portion (14a) is provided with a third recess (26a) having a third bottom surface (28a) and a second minor side portion (14b) is provided with a fourth recess (26b) having a fourth bottom surface (28b), the third and fourth bottom surfaces (28a, 28b) extending across the longitudinal axis (6). Thus, the cutting insert may be supported in a relevant gear milling cutter against one of the first and second bottom surfaces and against one of the third or fourth bottom surfaces. |
