The Chicago Pneumatic CP7778 1" Drive Heavy Duty Air Impact Wrench is built for demanding, high-torque applications found across Class 6–8 trucks, buses, and various heavy equipment. This robust tool delivers consistent, reliable performance essential for professional fleet maintenance, industrial operations, and construction environments, providing the power needed for challenging fastening tasks requiring significant torque.

Key Features

  • High Breakaway Torque: Generates up to 1,620 ft-lbs (2,200 Nm) of maximum reverse torque, effectively loosening rusted, over-torqued, or large-diameter fasteners typically encountered on heavy machinery.
  • Professional-Grade Durability: Features an all-metal housing and a reliable pinless rocking dog clutch mechanism, ensuring consistent power delivery and extended tool life for continuous use in professional workshops and field service.
  • Precision Control: A three-position power regulator and an intuitive forward/reverse selector allow technicians to optimize torque output for specific applications, minimizing the risk of fastener or material damage.
  • Ergonomic D-Handle Design: The D-handle with an inside trigger provides stable two-handed control and balanced handling, enhancing accuracy on stubborn fasteners and helping to reduce operator fatigue during extended periods of use.
  • Optimized Exhaust Flow: An angled-down exhaust system directs air away from the operator and the immediate work area, contributing to improved comfort, visibility, and cleanliness on the job site.
