Abstract:
1. Cutting insert for chip removing machining, the cutting insert comprising an elongate center part, cutting edges being arranged at the opposite ends of the center part, the cutting insert being provided with engagement members along two longitudinal, opposite sides, the cutting edges forming, in an end view of the cutting insert, a mutual angle (α), wherein rake faces associated with the respective cutting edge are facing opposite directions in the vertical direction of the cutting insert, and the angle (α) between the cutting edges is in the interval of 10°<α<20°, a distance (H 1 ) being measured between the intersection of the cutting edge with a center line (C 1 -C 1 ) of the cutting insert and the outermost portion of the lower to engagement member and in that in an end view of the cutting insert, the ratio between the distance (H 1 ) and the height (H) of the cutting insert is the following: 0.5H≦H 1 ≦0.7H, the distance (H 1 ) and the height being measured along a center line (C 1 -C 1 ) of the cutting insert.
