Chicago Pneumatic unveils light ultra-compact butterfly impact wrench

Chicago Pneumatic has launched a new butterfly impact wrench as part of its new series of ultra-compact vehicle service air tools. The company says the 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 manoeuvrability in tight spaces.

The mini butterfly impact wrench has been added to Chicago Pneumatic’s portfolio in direct response to user demand for smaller, lighter tools. It’s size and weight means it is ideal for transmission and engine repair works, body panels, oil pans, ignitions, motorcycle repair and vehicle seats.

The CP7711/21 butterfly ultra-compact ¼” and 3/8” wrench weighs just 1.16lbs (0.53kg) and delivers 80 ft-lbs (110Nm) of maximum torque in reverse, giving an excellent 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 areas. 

The impact wrench is just 5.5 inches long (140 mm) and 1.5 inches wide (40 mm) and is ergonomically designed to fits neatly into the user’s hand. Chicago Pneumatic says 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.

The CP7711/21 is constructed with an aluminium housing and a high durability single hammer mechanism, ensuring the tool can be used in the tough environment of the workshop.
