Abstract
A clamping device is arranged for releasably holding a tool holder shank. The clamping device includes a housing, a drawbar mounted reciprocally movable inside a bore in the housing, and an actuator. An aperture extends along an actuator axis and is delimited by an aperture housing surface and a drawbar groove. A first locking pressure applying surface on the actuator acts upon a first locking pressure receiving surface in the drawbar groove to effectuate a displacement of the drawbar when the actuator is moved along the actuator axis in a first direction, resulting in clamping of the tool holder shank.
