Abstract:
PCT No. PCT/DE89/00480 Sec. 371 Date Jan. 22, 1991 Sec. 102(e) Date Jan. 22, 1991 PCT Filed Jul. 19, 1989 PCT Pub. No. WO90/00957 PCT Pub. Date Feb. 8, 1990.A tool for use in a hand power tool has a tool shank to be received in the hand power tool and two diametrically opposite recesses formed in the tool shank for receiving locking bodies of the power tool, and at least three rotary driving grooves open at a rear end surface of the tool shank and located on both sides of said longitudinal plane passing through the two recesses, and symmetrically relative to a plane of symmetry that extends transverse to the longitudinal plane for receiving strip-shaped rotary drivers of the hand power tool. The at least three rotary driving grooves are distributed along a circumference of the tool shank in such a manner that two rotary driving grooves are never located diametrically opposite to each other. The sum of cross-sections of rotary drive grooves located on one side of the longitudinal plane is substantially equal to a sum of cross-sections of rotary drive grooves located on another side of the longitudinal plane.
