Each of the intersection lines between the side surface (18,19) and the top surface (16) of the cutting insert forms a main cutting edge (24,25) respectively. Protruding ends (22,23) respectively intended to plane out the machined surface. The main cutting edges and bevel faces are separated in each corner of smoothly rounded corner edges (28,29) respectively. The indexable cutting insert (13) formed as a parallelogram includes two essential parallel rectangular side faces, the top surface (16) and bottom surface (17) which are be mutually angled away from each other. Top and bottom faces extend two longitudinal side surfaces (18,19) and two end faces (20,21) perpendicularly oriented from top and bottom faces. The side surfaces are generally inclined from top face and from bottom face. The endfaces located in diametrically opposite corners are provided on protruding ends (22,23). |
