Ergonomics

1. Eliminates Torque Reaction for air & electric powered screwdrivers, nut runners, tappers and hand drills.
2. Tool and Arm Float Practically Weightless, reducing burden on operator.
   
3. DF Models Automatically Provide Air Tools with Down Force during Tool Rotation and weightless float when motor is idle. This “power assist” aids operator when driving self-threading fasteners or drilling holes.

Production Benefits

1. Keeps Driver in Alignment with Fastener and Workpiece. Helps eliminate cross threading, broken bits, screw head burrs and out of square fasteners.
2. Keeps Expensive Tools from being Dropped, Moved or Misplaced.
   
3. Tool Stays Right Over Work Area, Reducing Cycle Time.
   
4. Tapping Arms Thread Holes at a Much Lower Cost than a Machine Tool and at a Faster Rate. ETA Tap Arms are also great for a second operation in a casting, molded plastic part or in punched sheet metal.... wherever threads are required.
