<p>The drill (10) has a machine housing (26) with a drive motor to rotatably drive a spindle (13) which receives a releasing or tightening torque when a tool is changed or when a tool holder (12), threaded to the spindle, is replaced. The tool holder can non-rotatably couple the spindle relative to the housing via a locking device which automatically opens, during a torque transmission from the tool holder, in the reverse direction. A locking coupling can be coupled via a gear stage to the spindle.</p> |
