Claim Text:
1. Indexable cutting insert for grooving or parting, comprising a plate-shaped main body with two parallel main surfaces and a peripheral surface joining the two main surfaces and comprising a plurality of sections that are angled with respect to one another, wherein four cutting edges extending transversely to the main surfaces are provided on a peripheral surface on the transition of sections of the peripheral surface that are angled with respect to one another, wherein in plan view of the main surfaces, the position of the cutting edges defines an imaginary quadrilateral, wherein the imaginary quadrilateral has two short and two long sides, wherein the cutting edges are oriented in each case, oppositely on adjacent corners of the imaginary quadrilateral in a peripheral direction and oriented in the same direction on diagonally opposite corners of the imaginary quadrilateral, wherein sections extending along the shorter sides of the peripheral surface of the imaginary quadrilateral comprise a positioning notch that includes a concave-shaped portion with a radius, wherein the radius is smaller in a center of the positioning notch than a radius of a pin provided for engaging with the positioning notch, and wherein cutting surfaces of cutting edges are oriented to face the adjacent long side of the imaginary quadrilateral and to turn away from the adjacent short side of the imaginary quadrilateral.
