ABSTRACT:
A cutting insert for chip removing machining is provided, the cutting insert including 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). A tool is also provided and includes such a cutting insert. The cutting insert includes rake faces associated with the respective cutting edge that are facing the opposite direction in the vertical direction (H) of the cutting insert, and the mutual angle (α) is in the interval of 10°<α<20°, and a distance (H1) is measured between the intersection of the cutting edge with a center line (C1-C1) of the cutting insert and the outermost portion of the lower engagement member and in that in an end view of the cutting insert, the ratio between the distance (H1) and the height (H) of the cutting insert is the following: 0.5H≦H1≦0.7H, the distance (H1) and the height being measured along a center line (C1-C1) of the cutting insert.
