Abstract
The present invention relates to a device for fastening a rotatory drivable tool to the head of a technoscope by screwing a tool holder provided at the proximal side end of the tool to the distal end of the shank of a drive spindle. To secure undesired detaching of the tool from the technoscope, the tool holder is additionally screwed onto and against a cylinder sleeve which is run through by the shank of the drive spindle and rotatably mounted in the technoscope head.
