ABSTRACT:
A quick action, cam operated hand tool holder, such as a tap wrench. The cam is moveable between at least one released and one locked positions, preferably by a conventional T-handle. A third position may also be provided which may be either a second locked or a second released position. An adjustable nut, or similar, retains a collet within the wrench and adjusts the wrench to different sizes of tools (i.e. taps) and adjusts the gripping force applied when the cam is locked. The collet is preferably reversible, accommodating different tool sizes on each end, but may also be single ended.
