The Chicago Pneumatic CP7748 is a professional-grade 1/2-inch air impact wrench delivering over 1,200 ft-lb of nut-loosening torque — making it one of the most powerful composite 1/2" impacts available. Weighing just 4.4 lbs, it features a composite housing with aluminum back cap and a thermoplastic rubber injected grip for exceptional durability and all-day comfort in demanding shop environments.
Engineered for professional mechanics, the CP7748 uses a twin hammer mechanism and a robust air motor design that resists dirt and debris better than competing composite tools. A quiet handle exhaust keeps noise levels down, while the full-teasing ergonomic trigger gives precise speed control — ideal for automotive repair, heavy equipment maintenance, and industrial assembly applications.
