CP7762 Wrench Gets into Small Spaces

Aug. 9, 2017
Chicago Pneumatic releases the first stubby impact wrench that gets into small spaces.

A truly compact 3/4 in. stubby impact wrench, the CP7762, measures just 6.2 in. (158.7 mm) in length and weighs a mere 6.6 lb. (3.0 kg). Small but powerful, the CP7762 is equipped with a rugged steel motor that delivers a powerful 1,050 ft-lb. (1,420 Nm) in reverse for high productivity. Featuring a twin hammer action and aluminum housing, the CP7762 is capable of delivering optimum performance in the toughest operating environment.

 

Operator comfort is an integral part of this new stubby impact wrench's design. This is evident in the fact that the CP7762 is a well-balanced tool and features an ergonomic P-handle with a full teasing trigger. The controls are designed and positioned for ease of use and include a one-hand forward and reverse speed regulator button and a side-to-side forward and reverse system.
