ABSTRACT:
A tool holder with radial adjustment means. The tool holder has a connecting portion having a connecting shank, an intermediate portion and a head portion, and a tool receiving means for a tool, in particular a rotary tool. All three portions (2, 3, 4) are of substantially disc-like configuration and bear against each other with their faces (2a, 3a, 3b, 4a) which extend radially with respect to the axis (A) of the connecting shank. Provided at the periphery of the connecting portion (2) are two diametrally oppositely disposed recesses (8) into which two claws (9) arranged on the intermediate portion engage with radial play. Provided at the periphery of the intermediate portion (3) are two diametrally oppositely disposed recesses (14) which are displaced through 90.degree. relative to the claws (9) and into which two claws (15) disposed on the head portion (4) engage with radial play. A first screwthreaded spindle (11) can be screwed in the connecting portion (2), in a first screwthreaded bore (10) which extends between the two recesses (8) of the connecting portion, the ends (11a, 11b) of the first screwthreaded spindle bearing without play against the claws (9) of the intermediate portion (3). A second screwthreaded spindle (17) can be screwed in the intermediate portion (3) in a second screwthreaded bore (16) extending perpendicularly to the first screwthreaded bore (10) and with its ends bears without play against two diametrally oppositely disposed inside surfaces of the head portion (4). Clamping screws (22, 25) which are in axis-parallel relationship are provided for pressing together the faces (2a, 3a, 3b, 4a) of the three portions (2, 3, 4).
