Chicago Pneumatic 6151590250 1/2 in Air Impact Wrench

Product Description

The CHICAGO PNEUMATIC 6151590250 is a 1/2 inch drive pneumatic impact wrench built for industrial maintenance and trade applications. Powered by compressed air at 90 psi, it delivers up to 701 ft/lb of torque at 9,000 RPM with 1,400 blows per minute. The compact composite body keeps weight at 5.9 pounds, making it manageable during extended overhead or confined-space work. Air inlet is 1/4 inch NPTF, and the tool consumes 25.4 CFM at rated pressure. The handle exhaust directs spent air away from the work area and the operator. A friction ring retainer secures the socket. This wrench is sized for automotive, fleet, and industrial fastening tasks where a full-size impact gun would be impractical.

This impact wrench is suited for residential and commercial service environments, including automotive shops, fleet maintenance bays, HVAC equipment installation, and general industrial assembly. The pistol grip handle style and compact form factor make it practical for use in tight engine compartments or mechanical rooms where larger tools cannot reach. It requires a minimum 3/8 inch air supply hose and a compressor capable of sustaining 25.4 CFM at 90 psi for continuous operation.

Installation Notes

Installation and operation should be performed by a qualified mechanic or pneumatic tool technician. Before connecting or disconnecting the tool, depressurize the air line and verify the supply valve is closed. Ensure the air supply hose meets the minimum 3/8 inch inside diameter requirement and that all fittings are rated for the operating pressure. Hearing protection is required during operation given the 94 dB sound level.
