摘要：
The invention relates to a cutting insert, in particular for machining crankshafts, having two base surfaces (10, 11) which are arranged parallel to one another and through which a respective hole (12) passes for receiving a clamping screw and which merge at their shorter edges into rounded end faces which are each defined laterally by cutting edges. According to the invention, at least one pair of the cutting edges is of stepped design and has two convex sections (13, 14) and a concave section (15) lying in between, wherein the outer convex section (13) extends over an angle of 180°.
