Torque Reactionless Differential Hand Held Rotary Power Tools

The heavy financial burden that workers compensation and health insurance place on the aircraft industry is of crisis proportion. One of the leading contributors to this crisis is Cumulative Trauma Disorders (CTD's) that result from the use of hand held rotary power tools. The use of ergonomically designed power tools will greatly reduce the risk of developing CTD's and offers the aircraft industry a long term solution to reducing this cost.

This paper presents a hand held fastener installation tooling system based upon a revolutionary concept eliminating 100% of the reaction torque, that until now, the users of conventional tools have had to endure.
