Avoid Injury with Reduced-Reaction Tool Technology

Ergonomics or tool control? Until recently it’s been an either-or scenario. Manufacturers commonly think reduced reaction power tools don’t provide the torque control they need. Today, assembly tools with reduced-reaction technology are highly accurate, easy to integrate and are more ergonomic than ever before.

When manufacturers need precise tightening functions, they seek direct current (DC) tools for their closed-loop, transducerized capabilities. These tools are highly accurate and provide traceable results. The tools also create a reaction into the operators’ hands because the tools’ motor directly connects to the output shaft. The operator then absorbs a “kick-back” from the tool when it delivers torque to the fastener. If the operator doesn’t expect the torque reaction or is not properly prepared or positioned to safely absorb it, the operator can be instantly injured. After repeated use, operators may experience discomfort or develop a chronic injury.

Alternatives to DC tools are impact wrenches or hydraulic pulse tools. These non-direct drive tools don’t send nearly as much force back to the operator. However, these tools typically are less accurate and harder to control.
