  • TOOL HOLDING FIXTURE
    Publication number: 20170173704
    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 region (4) having a receiving opening (5) for a tool shank (6) of the tool (2), and a rear holding region (7) to be held in a work spindle of a machine tool. In order to achieve a reduced mass, a lower mass moment of inertia and at the same time high stiffness, a sleeve (11), made of a fiber reinforced plastic, is disposed in at least the front clamping region (4).
