A rotating tool for chip removing machining comprises a rotatable holder part (1) and a detachable cutting part or loose top (2). In a front end portion of the holder part, one or more forwardly open slots (8) are formed, which separate a number of elastically deflectable wings (9). For centring and clamping of the loose top (2) on the holder part (1), a male/female coupling is arranged, comprising on the one hand a male-like projection (11) placed centrally on the front end of the holder part (1), which projection is intersected by the slots (8) and divided into a plurality of projection elements (12), and on the other hand a seat (13) formed in a rear end of the loose top (2) and located centrally in the same, into which seat the projection is insertable in an unloaded state. A tightening screw (23), accessible from the outside, is arranged to distance the projection elements (12) from each other when the male projection is inserted into the seat (13), more precisely with the purpose of pressing the external surfaces of the projection elements against internal surfaces in the seat (13), thereby clamping the loose top on the holder part.
