ABSTRACT:
A tool holder for a tool which can be rotated about an axis of rotation, in particular a drilling, milling or reaming tool, comprises a clamping shank which, in an end shank region (7), has an accommodating opening (9) which is central in relation to the axis of rotation and is intended for accommodating a retaining shank of the tool. Clamping surfaces for securing the retaining shank of the tool with a press fit are arranged on the circumferential casing of the accommodating opening. According to the invention, the end shank region (7) of the clamping shank has a plurality of at least more or less axially extending tension spokes (13) distributed in the circumferential direction, it being possible for said tension spokes to be subjected to an essentially radially outwardly directed tensile force in order for the clamping surfaces to be spread apart radially from one another. Acting on the tension spokes (13) are bridge elements (19) which bridge the circumferential spacing between the latter and of which the chord length measured between the points of attachment of the bridge elements to the tension spokes (13) can be increased when the tension spokes (13) are subjected to the action of tensile force.
