Abstract
A toolholder support member for retaining the shank of a toolholder has a bore to accept the toolholder shank. A retention member extends through the bore wall to engage a perforation extending through the shank or indentation within the shank, thereby retaining the shank within the receiving bore. The retention member is biased to provide resistance for insertion or extraction of the shank within the receiving bore. Furthermore, the retention bore is angled relative to the longitudinal axis of the receiving bore so that the force required to insert the toolholder within the receiving bore is minimized, while the force required to extract the toolholder from the receiving bore is maximized.
