Chicago Pneumatic 6151590180 3/8 in Air Impact Wrench

Product Description

The CHICAGO PNEUMATIC 6151590180 is a compact, pistol-grip air impact wrench built for industrial maintenance and professional trade use. Driven by a 3/8 inch square drive, it delivers up to 332 ft/lb of torque at 11,500 RPM with a striking rate of 1,250 blows per minute. The composite body keeps the tool lightweight at 3.8 pounds while maintaining durability under continuous shop use. A handle exhaust design routes spent air away from the work area, improving comfort during extended operation. Licensed mechanics, HVAC technicians, and general maintenance professionals will find this wrench well-suited for fastener removal and installation in tight spaces.

This wrench is designed for air-powered applications in automotive, HVAC, and general industrial maintenance environments. It operates on a 1/4 inch NPT inlet at 90 psi and consumes 8 CFM of air, requiring a minimum 3/8 inch hose for proper supply. The compact tool style at 7 inches overall length allows access to confined fastener locations on equipment, ductwork frames, and mechanical assemblies. It is appropriate for both shop and field use where a reliable, lightweight impact wrench is needed in place of larger 1/2 inch drive tools.

Installation Notes

Installation and operation should be performed by qualified mechanics or trade professionals familiar with pneumatic tool safety. Before connecting or disconnecting the air supply, shut off the compressor and bleed the hose line. Verify the air supply is clean, dry, and regulated to 90 psi with a minimum 3/8 inch inside-diameter hose to maintain rated performance. Follow applicable workplace safety standards and wear appropriate hearing protection, as the tool produces up to 100 dB during operation.
