Patent ID: 7488142

Claim:
A tool for chip removing machining, comprising: a basic body; a replaceable cutting body; a male/female coupling between the basic body and the cutting body, the male/female coupling including: a plurality of male-like fingers peripherally spaced-apart around an axis, each individual finger including an underside, a free end, and a pair of opposite wedge surfaces converging at axial angle of convergence toward the underside; and at least equally as many spaced-apart seats into which the fingers can be pressed axially, each seat being delimited between elastically resilient projections defining pairs of support surfaces of adjacent projections, the support surfaces diverging at an angle of divergence; wherein the fingers, upon pressing-in toward a lower end position, having the purpose of bending away the projections, while the fingers are wedged up between the projections and are subjected to a spring force from the same; and a tightening member fixing together the basic body and the cutting body; wherein the axial angle of convergence of the two wedge surfaces of each individual finger differs from the angle of divergence of the pair of cooperating support surfaces of the projections in the state when the projections are not loaded by the fingers.
