Abstract

A tangential indexable cutting insert having eight lips which are distributed in pairs over four side faces of the indexable cutting insert, each lip being formed by a main lip which is formed by the intersection of one of the side faces with a base face, a secondary lip, which is formed by the intersection of the side face with an adjacent side face, and a corner edge () adjoining the main lip and the secondary lip, is distinguished by the fact that the main lip has a front portion () which is located at the level of the corner edge, a rear portion which is located at a lower level closer to a center axis of the indexable cutting insert, and a transition portion between the front portion and the rear portion, the three portions being located in one plane.
