Abstract
An indexable cutting insert for metal machining, in particular turning, is formed with banana- or C-shaped protrusions (11) adjacent to each operative cutting corner. The concave side of the protrusion faces in a direction towards the cutting corner. In comparison with corresponding inserts without such a protrusion a better chip control is achieved. Thus, the chip flow is led away from the machined surface both at small and large cutting depths and the chips are broken into suitable lengths.
