FIELD: cutting.
SUBSTANCE: cutting insert for cutting processing with a relatively large supply comprises a beveled surface including a reinforced front sub-edge extending between two sub-edges of the convex angle. The cutting width WC is determined between the distal points of the first and second sub-edges of the convex angle. The cutting width WC complies with the condition: WC ≤ 6 mm. The minimum thickness TF of the front sub-edge complies with the condition: TF > 0.20 mm.
EFFECT: processing productivity and durability of the insert are increased.
