The drill chuck has chuck jaws (2), a jaw-guide part (4) guiding the chuck jaws at an angle to the chuck axis (3) and a clamping-thread part (6) having a clamping thread (5) for adjusting the chuck jaws (2) and driven by the percussion drilling spindle (1) in such a way as to be fixed in terms of rotation, the jaw-guide part (4) and the clamping-thread part (6) being guided on one another in such a way as to be mutually rotatable and being supported against one another axially in a positive-locking manner at (7). The clamping-thread part (6) has axial clearance of motion relative to the percussion drilling spindle (1), and the jaw-guide part (4) has a stop (16) which limits the axial displacement of the percussion drilling spindle (1) on the jaw-guide part (4) within the axial clearance of motion of the clamping-thread part (6). …<IMAGE>… |
