FIELD: material processing.
SUBSTANCE: group of inventions relates to the treatment of materials by cutting and can be used for milling shoulders. The cutting plate has a triangular shape and has the first surface, the second surface and a peripheral surface located between them. The peripheral surface includes a recessed peripheral tapered portion and the first and second flank surfaces extending along the first and second main cutting edges. Each of the first and second flank surfaces forms a negative nominal clearance angle. Each of the first and second major cutting edges is located within the recessed peripheral neck when viewed from the first and second surfaces, respectively.
EFFECT: tool life is increased.
