Abstract:
The invention relates to a tool holding fixture (1) for rotationally driven tools (2), said tool holding fixture comprising a rotationally symmetrical holding body (3) which has a front clamping portion (4) having a holding opening (5) for a tool shaft (6) of the tool (2), and a rear holding portion (7) to be held in a work spindle of a machine tool. To achieve a reduced mass, a lower mass moment of inertia and at the same time high stiffness, a sleeve (11) consisting of a fiber-reinforced plastic is arranged at least in the front clamping portion (4).
