ABSTRACT:
A cutting tool includes a basic body and a cutting body that is fixable to the basic body via a male/female coupling. The coupling includes male-like fingers and female-like seats, which are delimited between elastically resilient projections. Each finger includes two converging wedge surfaces, which are pressable against a pair of diverging support surfaces of two adjacent projections. The axial angle of convergence of the two wedge surfaces of an individual finger differ from the angle of divergence of the two co-operating support surfaces of the projections, as long as the fingers are not loaded against the projections. In such a way, the removal of the cutting body from the basic body is facilitated.
