Abstract

The device has a conducting holding section (6) on its free end with a central bore (7) for force-locking accommodation of the tool (1) shaft (9) and an induction coil (10) for heating the holding section. A screening sleeve (23) of magnetically conducting and electrically weakly to non-conducting material is provided that engages at least partly in the coil opening with contact with the free end of the holding section.
