Based on the original Pneutorque, the 'Standard Series' range is a direct result of over 30 years of refinement and development necessary to keep pace with industry's requirements today. In use on many thousands of applications worldwide, Pneutorque Wrenches continue to represent the foundation of Norbar's powered tool range. The Automatic Two Speed gearbox offers the same time saving advantage as the 'manual' version but requires no operator intervention. Because the Automatic gearbox changes without having to stop the tool, the tightening cycle can be completed faster.
