Designed for light-vehicle tire changing in workshops and roadside assistance, the Chicago Pneumatic CP8854K Cordless Impact Wrench Kit combines a 1/2" square drive, 4,500 RPM free speed, and 774 ft-lbs maximum reverse torque in a cordless configuration. Its 18V platform provides the mobility of a cordless tool while maintaining a compact format similar in length and weight to a high-performance 1/2" pneumatic impact wrench.
The CP8854K features a 0–88.5 ft-lbs forward working torque range and a two-stage forward trigger with a snugging function to help improve fastening productivity. A forward shut-off position helps prevent overtightening, while the specified 9.3 m/s² vibration level and 87 dB(A) sound pressure provide defined operating characteristics for tire service applications. The pack configuration includes the battery and charging station, unlike the bare-tool version.
