ABSTRACT:
The invention relates to a toolholder assembly. The toolholder has a tubular shank at one end for mounting into the bore of a support member. The shank has at least two circumferentially spaced perforations in its tubular wall. Each of the bores extends obliquely toward the rear of the shank as it extends from the outer to the inner surface of the tubular wall. A locking element is located partially within each of said perforations an 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 perforation walls, thereby expanding the rear of the tubular shank to lock the shank in the support member bore.
