Designed for light-vehicle tire changing in workshops and roadside assistance, the Chicago Pneumatic CP8854-2 Cordless Impact Wrench combines a 1/2" square drive, 4,500 RPM free speed, and 774 ft-lbs maximum reverse torque in a cordless bare-tool configuration. Its 2" extended anvil provides additional reach for compatible sockets, while the two-stage forward trigger includes a snugging feature and a forward shut-off position to help improve fastening productivity and prevent overtightening.
The CP8854-2 is supplied as a bare tool, so the battery and charging station are not included. It uses the Chicago Pneumatic 18V battery platform and delivers a specified 0–88.5 ft-lbs forward working torque. The extended configuration measures 9.41" in length and weighs 4.78 lb without the battery, while its 9.3 m/s² vibration level and 87 dB(A) sound pressure provide defined operating characteristics for mobile vehicle service.
