Chicago Pneumatic unveils light weight ultra-compact butterfly impact wrench CP7711/21 for vehicle service


The new Chicago Pneumatic CP7711/21 ultra-compact butterfly wrench is the lightest tool of its type on the market and 15% smaller than its predecessor, which means it offers mechanics and vehicle service professionals’ unrivalled access and maneuverability in tight spaces. The mini butterfly impact wrench has been added to Chicago Pneumatic’s portfolio in response to user demand for smaller, lighter tools and is the perfect tool for transmission and engine repair works, body panels, oil pans, ignitions, motorcycle repair and vehicle seats.

The CP7711 and CP7721 butterfly ultra-compact ¼” and 3/8” wrenches weigh just 1.16lbs (0.53kg) and deliver 80 ft-lbs (110Nm) of maximum torque in reverse, giving an unsurpassed power to weight ratio. As a result, users can be sure the wrench will easily remove or tighten fasteners in the most difficult-to-reach applications.

Ultra-compact in size at just 5.5 inches long (140 mm) and 1.5 inches wide (40 mm), the butterfly impact wrench is exceptionally ergonomic and fits neatly in a user’s hand. Its light weight and small size make it incredibly user-friendly and more comfortable to operate than alternative tools, and as such can be used for longer periods of time without causing strain to the user. The forward and reverse butterfly lever is placed on the top for easy operation, while the built-in 180° air inlet swivel and the three speed power regulator are positioned at the back of the tool.

In line with Chicago Pneumatics’ ethos of high quality and rugged reliability, the CP7711 and CP7721 are constructed with an aluminum housing and a high durability double rocking dog mechanism, ensuring the tools can be used in the tough environment of the workshop. Our new ultra-compact range brings users small yet exceptionally powerful tools that really are the perfect companion for the workshop toolbox.
