Zusammenfassung:	PCT No. PCT/DE89/00687 Sec. 371 Date May 24, 1991 Sec. 102(e) Date May 24, 1991 PCT Filed Oct. 26, 1989 PCT Pub. No. WO90/06210 PCT Pub. Date Jun. 14, 1990.For a hand power tool (1) with a multi-part manually operable quick-action chuck (2) for a disc-shaped tool (3) which is held on a shoulder (4) of a drive spindle (5) and onto which a force can be loaded from the other side by a pressure plate (7), with the pressure plate (7) concentrically embracing a threaded part (13) and being arranged positionally secured in relation to the threaded part and rotatable, with a hand screw part (11) embracing the threaded part (13) and th pressure plate (7) like a sleeve, and forming an annulus (14) with these, which contains at least a rolling contact bearing (9) and a drive which couples together the hand screw part (11), the threaded part (13), and the pressure plate (7), for improved function and a simplified design, and for a limitation of the maximum clamping pressure on the tool, a rolling planetary drive is formed from at least one of the rolling contact bearings (9, 12) in conjunction with a springly element (10), the drive which couples the pressure plate (7), the threaded part (13), and the hand screw part (11).
