A double-sided cutting insert for milling, in particular for face milling, includes first and second cutting edges each having alternately disposed main lips and secondary lips which each extend between active and passive cutting corners. Each main lip, starting from a first distance from a reference plane at an active cutting corner, extends in a manner dropping monotonously to a smaller, second distance from the reference plane at a passive cutting corner. That end of a secondary lip that adjoins the active cutting corner is in each case at a greater distance from the reference plane than the other end of the secondary lip that is remote from the active cutting corner. A circumferential side surface has, immediately adjacent the secondary lips, in each case planar secondary flanks and each secondary lip is formed at least regionally in a convex manner in plan view of the associated secondary flank.

Double-sided cutting insert for milling

A cutting tool has a main tool body and at least one insert seat disposed thereon. The seat has a bottom surface for mounting a cutting insert, and further has a dowel pin, which penetrates a through-hole of the mounted cutting insert and the bottom surface and can be fixed to the main tool body. A center longitudinal axis of the fixed dowel pin is arranged at an acute angle with respect to the bottom surface. The dowel pin contains a spherical segment for mounting on a bearing surface of the through-hole. The surface of the spherical segment is interrupted by a segment groove.
