Chicago Pneumatic has introduced a new powerful ½” impact wrench for vehicle service specialists. Building on the popularity of the previous model, the latest CP7748 has been designed to offer operators unparalleled levels of power, comfort and durability and is suitable for workshop or roadside assistance tasks such as tyre changing.

Antoine Tourneux, Global Product Marketing Manager, Vehicle Service Air Tools, at Chicago Pneumatic comments, “Listening to our customers, we recognised a demand for more ergonomic tools and we have added this lightweight solution that is easy to use and which ultimately helps users to increase productivity and cost-effectiveness.”

Weighing in at just 4.4 lbs (2 kg) and delivering 960 ft. lbs (1,300 Nm) of power in forward and reverse, the CP7748 impact wrench provides a high power-to-weight ratio. This is more power than its predecessor and so the tool delivers improved efficiency and reduced operation time.

The impact wrench is equipped with a wealth of new design features to maximize comfort. At the heart of the design is an innovative forward/reverse and power control ring system, which is more ergonomic than controls on the back of the tool. Users can either change direction by pushing buttons easily with one hand, or simply by turning the ring from anywhere around the tool. The CP7748 also offers two different settings in the forward position (40 per cent of maximum power and full power) and a full power setting in reverse. This ring system facilitates the use of the CP7748 in tight places without having to remove the tool to change direction. Furthermore, the system also reduces fatigue on operators’ wrists and arms when switching between forward and reverse or adjusting the power.  

Thanks to its compactness, the CP7748 can comfortably be used in confined spaces. The tool is 14% t shorter than its previous version, measuring just 175 mm in length. This new wrench also features a 360° swivel air inlet to provide high manoeuvrability and comes with a curved handle which uses rubber material at the back of the tool to provide excellent handling while helping to prevent the tool from slipping.

For durability the tool has a hard chromium aluminium cylinder that surrounds the motor and twin hammer mechanism.
