[origin: US6092814A] PCT No. PCT/DE97/00203 Sec. 371 Date Jul. 22, 1998 Sec. 102(e) Date Jul. 22, 1998 PCT Filed Feb. 3, 1997 PCT Pub. No. WO97/28930 PCT Pub. Date Aug. 14, 1997A tool holder (10) is proposed for tools inserted into machines for drilling and/or percussion operation having means for rotational driving and axial locking of a tool shank which can be inserted into a tool receptacle (11) of the respective machine, wherein a plurality of axial strips (13) which project inward radially are provided for rotational driving and at least one radially lockable locking body is provided at the tool holder (10) for locking. In order to accommodate tool shanks of two grooved shank systems with different outer diameters, two axial strips (13) which are located opposite from one another and are directed inward radially are arranged at the receptacle bore (12). The axial strips (13) are guided such that they can be released outward radially, particularly in a springing manner, wherein the axial strips (13) engage in corresponding grooves (20) of the respective inserted tool shank (19) for rotational driving.
