FIELD: mechanical engineering. SUBSTANCE: cutting insert is intended for operations of machining grooves. Insert is triangular in shape and has upper and lower surfaces. Each angle of insert is provided with main cutting edge which is located primarily in perpendicular to direction of feed and with auxiliary edges which converge in direction of feed. In each protrusion, part of front surface is made in the form of bevelled face which at least partially protrudes beyond upper surface. Back face of main cutting edge is made of height which is equal to or less than height of insert. EFFECT: higher efficiency. 12 cl, 7 dwg
