摘要： A negative insert (1) f o r cutting machining h a s a top side (6), a clearance side (7) perpendicular thereto and a cutting edge (8) in a 5 region interconnecting these sides and extending substantially in p a r a l l e l with t h e s e sides. The insert has further a flat or rounded chamfer (10) connecting said cutting edge to said clearance side on at least one lateral side of the insert in the region of a corner thereof. The chamfer makes an angle of 1°-15° with the clearance side for 10 enabling application of the chamfer substantially tangentially to a w o r k piece (12) to be machined for bearing of the insert in two d i - m e n s i o n s against said work piece during cutting machining o p e r a t i o n carried out by the insert.
