Abstract
A cutting insert for grooving and parting as well as profiling and longitudinal turning of metallic work-pieces, includes a shaft part and at least one cutting head. There is a front end surface at the front end of the cutting insert, and a rear end surface at the rear end of the cutting insert. The shaft part includes a top side, a bottom side and side surfaces extending between the tope and bottom two sides. The cutting head carries a cutting edge defined by the intersection between a chip surface and a clearance surface. The cutting edge has a circular shape and has mainly a constant curvature between the ends thereof. The chip side of the cutting head is provided with a first chip-forming device placed immediately inside the cutting edge.
