Claim:
A tool holder comprising: a center axis; a chucking device having at least one collet chuck insertable into a hollow shaft of a tool; a tension rod having at least one engagement part, the tension rod movable in a direction of the center axis and cooperable with the at least one collet chuck such that in a first function position of the tension rod the at least one collet chuck is displaced radially outwardly into a chucking position, and in a second function position of the tension rod the at least one collet chuck is able to yield radially inwardly in the direction of the center axis; and an actuating unit cooperating with the tension rod, the actuating unit having an actuating element which is movable at an angle of 90° relative to the center axis, and which includes at least one actuating part, the actuating part and the engagement part forming a wedge mechanism, so that the actuating part causes an axial displacement of the tension rod when the actuating element is radially displaced.
