Abstract
An indexable cutting insert (10) for a tool (18) adapted to cut internal right-angled corners in a work piece (19). The insert (10) has a square configuration and comprises a top major surface (11), a bottom major surface (12) and connecting side surfaces (13). The lines of junction between the top major surface and the side surfaces define the main cutting edges (14) and the minor cutting edges (15). The main cutting edges (14) transite into the second cutting edges (15) in the corners of the insert. Each second cutting edge (15D) projects from the square basical shape so that it will lift the inactive main cutting edge (14A) from the machined surface under the insert.
