    摘要: A tool body assembly for use in chip-removing machining of a workpiece, comprising:
    - a drilling tool body (4) extending along a centre axis (C), wherein a peripheral insert seat (8) and a centre insert seat (9) are provided in a front end (5) of the tool body,
    - a coupling member (20) having a first end (21) configured for engagement with a rear end (6) of the tool body, and a second end (22) for fastening to a holder of a machine,
    - a securing member (30) configured to prevent axial motion of the tool body with respect to the coupling member,
    - torque transfer means (40) configured to transmit torque between the coupling member and the tool body, wherein the torque transfer means are positioned to allow fastening of the tool body to the coupling member in one of totally two available rotational positions, separated by 180°.

    摘要: In connection with implant work on the dentine, use is made of a machining instrument which is provided with an attachment part (31) for attachment to a rotary unit. The machining instrument can alternatively be applied in an extension unit which in turn can be applied to the rotary unit in a corresponding manner to the machining instrument. The extension unit has a thickened central section (17c) which is provided with a recess or opening (24), in which an inclined surface (29) is arranged. In the applied position of a machining instrument, one surface (30) of its attachment part is set against the inclined surface (29). A rotationally-fixed cooperation is present between the extension unit and the machining instrument. Moreover, a locking effect is achieved between the extension unit and the machining instrument as a result of a secure wedging effect obtained by means of the inclined surface. The rotary movement transmitted from the rotary unit to the extension unit is in turn transmitted to the machining instrument, which moreover is secured in the longitudinal displacement direction.
