ABSTRACT:
A cutting insert for chip removing machining, preferably for milling, includes a rake face and a clearance face. A cutting edge is arranged at the line of intersection of those faces. The rake face comprises at least two adjacent, elongated ridges which extend along at least a part of the cutting edge. A first ridge connects to the cutting edge. A second of the ridges is arranged to become active after wear of the first ridge. The first ridge becomes worn to a substantial degree before the second ridge is activated.
