<p>The chuck body (4) of the drill chuck has a tool holder (5) and an axial passage (60) which leads into the tool holder (5) and through which the percussion movement can be transmitted from the drill spindle (1) to the end of the drill, which is held between chuck-jaw pins (6) which run in the chuck body (4) in guide bores (9) and can be adjusted by means of an adjusting ring (10) which is rotatably arranged in an annular groove (11) of the chuck body (4) which is open to the outside and intersects the guide bores (9). At the rear margin of the annular groove (11), an annular rebate (20) is formed in the chuck body (4), in which annular rebate (20) an annular shoulder (21) provided on the adjusting ring (10) engages. The adjusting ring (10) is guided in the radial direction on the chuck body (4) only via the peripheral surfaces facing one another of the annular shoulder (21) and the annular rebate (20). <IMAGE></p> |
