CP | CP7748 | 1/2" Impact Wrench

Chicago Pneumatic impact wrench with high torque for auto repair and heavy-duty use in tight spaces

Best Impact Wrench for Stubborn Fasteners

The CP7748 impact wrench delivers the raw torque and ease of use professionals demand when faced with seized, rusted, or overtightened bolts. With a massive 960 ft.lbs of torque, this pneumatic powerhouse makes short work of lug nuts, crank pulley bolts, and suspension components, whether you're on the shop floor or in the field. Designed for serious performance without added bulk, it’s a go-to tool when your electric options fall short.

What Makes It Different?

Unlike typical air-powered wrenches that feel sluggish or clunky, the CP7748 is engineered with speed, balance, and comfort in mind. Its compact 7.5" body and lightweight 4.4 lb build reduce wrist fatigue in overhead or repetitive jobs. The one-handed forward/reverse switch adds efficiency in tight engine bays, while the rugged housing shrugs off oil, chemicals, and shop abuse. If you’re upgrading from older impact guns, you’ll immediately notice the faster breakaway torque and better control under pressure.

  • Higher torque-to-weight ratio than many competitors in its class
  • More compact for easier access in tight automotive or fleet service areas

How It Performs on the Job

Expect consistent, confident bolt removal even under extreme torque loads. The CP7748’s 8,200 RPM free speed ensures rapid spinning once bolts are free, speeding up tire rotations, brake jobs, and teardown tasks. Paired with a quality air setup, this wrench excels where cordless tools fade or overheat.

Ideal For:

  • Automotive repair shops and tire service centers
  • Heavy equipment maintenance crews
  • DIYers upgrading to professional-grade tools
