Abstract
The invention relates to a cutting insert for clamping into a disc-type or strip-shaped tool body, in particular, for milling crankshafts, whereby the insert is substantially cuboid-shaped and has two front faces, two side faces, serving as cutting faces as well as an upper and a lower side face, whereby a convex face is arranged between the front faces and the upper and lower side faces, so that the upper and lower side faces and the convex face form cutting edges each with a side face. According to invention, the cutting insert has an inwardly-tapered face adjoining the convex face, which allows the cutting edge to protrude and tapered chamfers are provided between the inwardly-tapered faces of the front face on both sides of a planar supporting surface to the outer edge.
