ABSTRACT:
A turning insert includes a chip-breaking surface and first and second clearance surfaces located at a corner of the insert. First and second edges are formed at a junction of the chip-breaking surface and the first and second clearance surfaces, respectively. The first edge defines a major cutting edge, and the second edge defines a finishing cutting edge. The major cutting edge is straight and transforms into the second edge by a sharp transition.
