An apparatus (10) is disclosed for releasably holding a toolholder shank (30) having a lockable surface (90, 95) and a releasable surface (185) utilizing an actuating bolt (20) with an associated threaded actuating nut (75). When the actuating bolt (20) is rotated in a locking direction, the actuating nut (75) is drawn onto the bolt (20) thereby clamping against the lockable surfaces (90, 95) of the toolholder shank (30). When the actuating bolt (20) is rotated in the releasing direction, a releasing segment (170) acts upon the toolholder (25) thereby ejecting it from the tool support member (15). |
