Chicago Pneumatic’s CP7755 series of impact wrenches


With its CP7755 series of premium half-inch impact wrenches, Chicago Pneumatic claims it now meets the needs of both tyre-changing and general mechanics. The CP7755 series combines easier and more accurate power control with greater ergonomics and comfort.

A choice of four models are available to meet different preferences and budgets. All versions feature the new patent pending power selection system. Power can be set to from as little as five per cent right up to 100 per cent of the tool’s maximum torque, for a precise match with each job’s requirements.

The patented Air Flex Mini air inlet feature is integrated into two models: CP7755 Air Flex Mini and CP7755-2 Air Flex Mini. It provides freedom of movement and turns any rigid hose into a flexible one, thanks to a multi-axis air connection swivel.

Ease of use is further enhanced by a flat-topped body shape, ensuring that when the tool is placed on the floor its hose extends upward. The operator can then conveniently pick it up by the hose without having to bend. Locating the regulator button in a recess is another user-friendly touch, as it helps avoid accidental activation if the tool is dropped.

Lightweight, compact construction and low levels of vibration add to the high-comfort appeal of the new wrenches. Among competitors in the same power class, CP7755 series impact wrenches have the top power-to-weight ratio. This is achieved by a specification that includes low-weight components like a composite motor housing, magnesium clutch housing and aluminum regulator.

Tyre-changing applications for CP7755 series impact wrenches include motorbikes, passenger cars, pickup trucks, vans and SUVs. General mechanics will find them useful for workshop and roadside assistance tasks on the same range of light vehicles, as well as medium- and heavy-duty trucks and tractor trailers, among other big vehicles used in diverse sectors such as agriculture, marine, mining and construction.
