<p>A tangential cutting insert (1) has a body with an operative front surface (2) associated with upper and lower main cutting edges (10), side auxiliary cutting edges (12) and corner cutting edges (14) therebetween. All cutting edges have rake surfaces (20, 22, 24) formed at the front surface and extending from their associated cutting edges in an inward direction of the cutting insert. The cutting insert has an imaginary reference plane (P) passing through extremities of the cutting corner edges (14) thereof. Each of the main cutting edges (10) extends from its associated corner edges (14) in an inward direction of the cutting insert away from the reference plane (P).</p> |
