ABSTRACT:
The quick-fastening device comprises only two parts separable during the fitting and removal of the bit, the first part being fixed to the tool and the second part being fixed to a motor-drive body. The axial locking and the rotational locking are ensured respectively by screwing and the engagement of two profiled ends of matching profiles.
