Central protrusion is located on the front face and is wedge-shaped in cross section Recess is located on the front face of insert and is opened to the side of its end face. Recess is symmetrical to insert longitudinal axis. length of cutting edge, which is formed by crossing of faces of central protrusion, equals not less than 0.1 and not more than 0.5 if insert length. Walls of recess and respective faces of central protrusion form two additional protrusions of wedge shape. Cutting edge of each additional protrusion is located at an angle to longitudinal axis of insert with angle vertex oriented towards main cutting edge. EFFECT: higher efficiency. 6 cl, 6 dwg
