Abstract:
1. An indexable insert for mounting in carrier tools for machining workpieces, comprising: a top side; a bottom side on which clamping depressions are situated; and a circumferential geometry which joins the top side and the bottom side; wherein cutting corners and cutting edges are situated at the transition from the top side and the bottom side to the circumferential geometry; wherein the clamping depression is composed of grooves which are situated on two intersecting straight lines, the two intersecting straight lines extending at right angles to one another; and wherein all grooves being situated at the same distance from the center axis or longitudinal axis of the indexable insert, and the point of intersection of the two straight lines lying on the center axis or longitudinal axis of the indexable insert, wherein the circumferential geometry has circumferential positive open spaces on both sides beneath the cutting corners and cutting edges which are recessed with respect to the cutting corners and cutting edges, thus providing a positive clearance angle on both sides; wherein a collar which is raised relative to the lowest points of the open spaces is situated between two open spaces which are oppositely situated, in relation to the top side and bottom side, on the circumferential geometry, and wherein the surface of the collar is a bearing surface in a carrier tool.
