Chicago Pneumatic has introduced a new powerful ½” impact wrench for vehicle service specialists. Built upon the heritage of the successful previous model, the 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 tire changing.
Weighing in at just 4.4 lbs (2 kg) and delivering 960 ft. lbs (1,300 Nm) of power in reverse, the CP7748 impact wrench provides a high power-to-weight ratio.
At the heart of the design is an innovative forward/reverse and power control set up based on a 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.
The CP7748 can comfortably be used in confined spaces since it is compact. The tool measures only 6.89 inches (175 mm) in length.
Chicago Pneumatic has designed the new impact wrench with durability in mind. Featuring a hard chromium aluminum cylinder that surrounds the motor and twin hammer mechanism, the CP7748 wrench delivers optimum performance in the toughest operating environment.
