Abstract (en)
[origin: WO2017202679A1] The invention relates to a cutting insert (14) for a tool (10) for machining a workpiece, comprising a first side (30), an opposing second side (32) and a borehole (26) running along a borehole axis (28), which penetrates the cutting insert (14) and extends from the first side (30) to the second side (32), comprising at least three cutting heads (20) distributed around the circumference of the cutting insert (14), each having a cutting edge (22) running transverse to the first and the second side (30, 32) and extending between the two sides (30, 32), wherein the at least three cutting heads (20) have a first cutting head (20'), a second cutting head (20) directly following the first cutting head (20') in the circumferential direction, and a third cutting head (20") directly following the second cutting head (20) in the circumferential direction, wherein the cutting insert (14) has a first contact surface (36) arranged on the first side (30), running orthogonal to the borehole axis (28) and at least partially surrounding the borehole (26), wherein the cutting insert (14) is rotationally symmetrical to the borehole axis (28) and is mirror-symmetrical to a central plane running perpendicular to the borehole axis (28), said central plane dividing the cutting insert (14) into two equally sized halves, and wherein, when viewed from above along the borehole axis (28), a notional straight connection line (46) between the cutting edge (22) of the first cutting head (20') and the cutting edge (22) of the third cutting head (20") does not cut through the borehole (26) nor the first contact surface (36).
