The Chicago Pneumatic 3/4" Impact Wrench, No. CP7769, is designed to be more compact, ergonomic and seven percent lighter than its predecessor, the company says. This wrench provides up to 1,440 ft-lbs of maximum torque and is designed with a twin-hammer mechanism to improve durability. All controls, including a variable speed trigger, can be adjusted with one hand, in any position, to help reduce fatigue on the operator's wrist and arm, and improve use in tight spaces. This wrench is also available with a 6" anvil (No. CP7769-6), and in a 1" version (No. CP7779).
