Abstract (en)
[origin: WO0205993A1] The invention relates to a tool holder for receiving a tool, especially a boring, milling, or grinding tool, which can be rotated about a rotational axis and which comprises a clamping shank. In a preferred form of embodiment, said clamping shank comprises a receiving opening (9) which is centrically arranged in an end socket (7) in relation to the rotational axis, said end socket being closed in an annular manner and said receiving opening being used for the interference fit of a holding shank pertaining to the tool. The end socket (7) contains a plurality of pressure chambers which are distributed in the circumferential direction and which extend at least approximately in the direction of the rotational axis. Said pressure chambers (13) can be connected to a pressure means supply which is especially hydraulic, in order to radially expand the receiving opening (9).
