Said clamping ring tubularly encloses the shaft section (2) or the drill shaft (30) and can be fixed thereon in different axial adjustable positions. The clamping ring (4) can b e tensioned on the drill (1) by means of tension screws (6) that extend therethrough substantially radially to the axis (7) of the drill. The tensio n screws (6) impinge the surfaces of the twisted flutes (9, 10) which are enclosed by the clamping ring (4) indirectly with a clamping shoe (19, 20) that is interposed in a twisted flute (9, 10). |
