FIELD: machine building.
SUBSTANCE: cutting plate contains the first mounting surface, the second mounting surface on the opposite side of the plate from the first mounting surface and the first lateral surface between the first mounting surface and the second mounting surface. The plate is designed with the groove passing diagonally through the first lateral surface and separating it into discrete, separate triangular first and second bearing surfaces. The first and second bearing surfaces are limited along the first and second edges by the front surfaces forming nonzero angles with the first and second bearing surfaces of the first lateral surface, and along the third edges - with the named groove.
EFFECT: removal of chips during processing of surfaces.
