<p>The invention relates to a drilling device comprising a drilling machine (2), which has a drilling spindle (5) that is rotatably supported in a machine housing (4), and a drilling chuck (3), which has a chuck body (6), a clamping cone (7) that can be rotated coaxially to the chuck body (6), and a jaw holder (8), in which clamping jaws (10) are guided in guiding receptacles (9), which clamping jaws are supported on a carrier (11) so as to be radially movable, the threaded section (12) of which carrier engages in a threaded socket (13) that is associated with the chuck body (6) and that is coaxial to the chuck axis. The drilling spindle (5) is designed as a hollow spindle, in which a coupling rod (14) that is connected to the threaded socket (13) in a rotationally fixed manner engages, wherein the coupling rod (14) can be moved between a clamping position coupled with the machine housing (4) in a rotationally fixed manner and a drilling position coupled with the drilling spindle (5) in a rotationally fixed manner.</p> |
