Abstract
A cutting insert (1) has an insert body (2) with an upper central clamping surface (3) and a lower clamping surface (4) through which passes an axis of symmetry (A) about which the cutting insert is indexable. The insert body (2) has a pair of opposite and identical cutting end portions (8A,8B) disposed laterally with respect to the upper clamping surface. The cutting end portions (8A,8B) each have a rake surface (9A,9B), a front cutting edge (11A,11B) and side cutting edges (15A,16A,15B,16B). Planes (20A,20B) passing through the midpoints (21A,21B) of the front cutting edges (11A,11B) and being normal thereto are inclined in opposite senses with respect to the axis of symmetry (A) in an end view of the cutting insert. A front cutting edge (11A) has at least two component cutting edges (22A,23A,25A), each pair of adjacent component cutting edges (22A,23A;23A,25A) overlapping via a common bridging section (26A,27A) thereby providing chip splitting means, each component cutting edge (22A,23A,25A) being associated with localized chip control means (27A,29A,30A) including chip breaking means.
