A cutting insert suitable for the milling of gray cast iron has a cutting corner defined between two angularly adjoining cutting edges at junctions between a rake face formed on one of the sides and respective clearance faces extending between the sides, a spherically segmental indentation being formed in the rake face at the corner and intersecting the cutting edges with respective arcs where the cutting edges adjoin at the corner, the cutting edges being linear over stretches thereof extending away from the arcs. |
