Abstract
The invention relates to a tool holder 1 for a rotating tool, especially a drilling head and/or milling head, comprising a drive shaft 4 that can be connected to a drive motor and a collet chuck 2 that is non-rotatably connected to the drive shaft 4 in order to hold the tool, whereby the drive shaft 4 and the collet chuck 2 are positively connected by means of a coupling element 5 for purposes of transmitting torque. In order to securely hold the tool and to concurrently have a simple construction of the tool holder 1, it is proposed for the coupling element 5 to be axially displaceable relative to the collet chuck 2 so as to release the tool.
