Abstract
A cutting insert for chip cutting machining, preferably for plane milling operations, has a generally square geometry and comprises a chip face and a number of clearance faces. A portion of the chip face is beveled and extends along a cutting edge from one cutting corner toward an adjacent cutting corner. The beveled portion is angularly oriented such that the insert obtains a more negative cutting geometry near the cutting corner than at a distance therefrom in order to achieve increased strength of the insert.
