ABSTRACT OF THE DISCLOSURE The invention relates to a toolholder for holding a tool at one end and having a tubular shank at its other end for mounting it into the bore of a support member. The shank has at least two circumferentially spaced perforations in its tubular wall. Each of the perforations extends obliquely toward the front of the shank as it extends from the inner to the outer surface of the tubular wall. A locking element is located partially within each of said perforations and the recess formed by the inner surface of the tubular shank. An actuating mechanism is located within the recess to drive the locking elements outwardly against the walls, thereby expanding the rear of the tubular shank to lock the shank in the support member bore.
