Patent ID: 7281888

Claim:
A tool for cutting machining, having a first tool part and having a second tool part, which exhibit a common axis of rotation, the first tool part exhibiting an alignment pin and, at a root of the alignment pin, an annular surface, and the second tool part exhibiting an axial bore to receive the alignment pin and an annular surface, which is capable of being tensioned against the annular surface of the first tool part with tensioning means for the axial tensioning of the two tool parts to one another, the tensioning means exhibiting three retaining screws arranged distributed around the periphery of the second tool part, which retaining screws are each screwed radially into a threaded bore of the second tool part ( 3 ) and each engage in a radial bore of the alignment pin, wherein the angle between a first retaining screw and a second retaining screw is smaller than 120° and larger than 90°, and in that the angle between the first retaining screw and the third retaining screw is identical with the angle between the third retaining screw and the second retaining screw.
