Abstract

A double-sided, indexable milling insert has a round basic shape defined by an imaginary cylinder, which is concentric with a center axis and extends between two reference planes that extend perpendicular to the center axis and are equidistantly separated from a neutral plane. The milling insert includes a pair of opposite chip faces located in the reference planes between which an envelope surface concentric with the center axis extends, a plurality of identical and alternately usable cutting edges along the peripheries of the chip faces, and lock means for rotationally securing the milling insert in one of several predetermined index positions. The individual cutting edge has the shape of a wave trough and includes two edge segments that meet at a bottom point.
