Abstract

A rotary-driven tool for cutting machining, in particular a drilling tool with a cutting body and a holder with a shaft piece is disclosed, with at least a cutter and a dovetail-shaped region on the cutting body and a matching dovetail recess on the holder. The cutting body can only be inserted in the holder laterally to a longitudinal axis of the holder. In order to fix the cutting body, opposing flank sections of the dovetail recess, between which the dovetail-shaped region fits can be moved over each other by means of a screw connection in the holder and on fixing the cutting body said body is subjected to a force on the axial direction by the screw connection. In one aspect, the cutting body is a cutting head and the axial force is exclusively generated by the dovetail-shaped region in cooperation with the dovetail recess in the holder.
