<p>The invention relates to a cutting insert, in particular an indexable cut ting insert (1) for machining predominantly metal materials, comprising a fi rst surface (5) that acts as a contact surface for a chuck tool and a depres sion in the first surface (5) in the cutting corner region and along the cut ting edges (2, 4), said depression acting as a swarf surface. According to t he invention, a second surface (27) that likewise acts as a contact surface is situated between the cutting edges (2, 4) and the first swarf surface bor ders (10) of the swarf surface that face the cutting edges (2, 4) and betwee n the cutting corner (6) and the second swarf surface border (30) of the swa rf surface, said border facing the cutting corner (6). To reinforce and stab ilise the cutting edge (2, 4), the first swarf surface border (10) and/or th e second swarf surface border (30) has or have one or more interruptions in the form of ribs (12, 16, 20) that extend in a substantially perpendicular d irection to the cutting edge (2, 4) and/or the cutting corner (6) into the s warf surface, said ribs (12, 16, 20) lying on the same plane as the second s urface (27).</p> |
