Abstract:
The invention proposes a tool holder (1), in particular of the shrink-fit chuck type, the receiving section (5) of which comprises clamping means (9) which are provided centrally with respect to an axis of rotation (7) of the tool holder (1) for holding a shank (15) of a rotary tool, and which define a receiving opening (13) for the shank (15). The clamping means (9) can be displaced in the radial direction between a radially widened release position for insertion or removal of the shank (15) and a clamping position, in which the clamping means (9) exert radial press-fit forces, which hold the shank (15) in a frictional lock on its cylindrical outer circumferential surface (19), on the shank (15). The clamping means (9) are assigned a clamping surface (17) with a cylindrical contour which, in the clamping position, bears against the outer circumferential surface (19) of the shank (15) with surface-to-surface contact.
