Pneumatic Impulse Wrench RED ROOSTER RRI-50STA - 1/4" Hex, 15-25 Nm

RED ROOSTER RRI-50STA is a professional pneumatic impulse screwdriver with automatic shut-off from the industrial pneumatic tools range of Rami Yokota. Designed for serial assembly applications, this model provides precise tightening, high repeatability and reliable torque control for consistent threaded joints.

Thanks to its impulse technology, the tool delivers high fastening performance with minimal reaction forces transmitted to the operator. The automatic shut-off function stops the tool once the preset torque is reached, preventing over-tightening and ensuring consistent assembly quality. The straight-body design allows comfortable operation in narrow and restricted areas, while the wide-body air motor provides reliable performance during extended production cycles.
