PCT No. PCT/EP95/00576 Sec. 371 Date Sep. 18, 1996 Sec. 102(e) Date Sep. 18, 1996 PCT Filed Feb. 17, 1995 PCT Pub. No. WO95/26258 PCT Pub. Date Oct. 5, 1995A rotary tool, in particular a high-speed milling or boring tool, has at least two balancing rings (17, 18) with a variable mass around their circumference mounted on the tool holder or tool body (1). Two concentric balancing rings (17, 18) whose position in relation to the axis of rotation (6) of the tool (1) may be adjusted are releasable mounted in the tool holder or in the tool body (1) and are supported in the radial direction (14) in the tool holder or tool body (1). A short rotary tool (1) is thus obtained with a simple support of the balancing rings (17, 18) in the radial direction.
