Built for light-vehicle tire changing in workshops and roadside service, the Chicago Pneumatic CP8854-2K Cordless Impact Wrench Kit combines a 1/2" square drive, 4,500 RPM free speed, and 774 ft-lbs maximum reverse torque for mobile fastening and fastener removal without an air hose. The 2" extended anvil provides additional socket reach for wheel-service applications, while the twin hammer mechanism delivers repeated impact action. A two-stage forward trigger provides a snugging function for initial fastener rundown, and the forward shut-off position helps limit overtightening. The kit configuration includes two 18V 2.5 Ah lithium-ion batteries and a charger, making it suitable for mobile automotive service where compressed air is unavailable or impractical.
A brushless motor and cordless configuration provide freedom of movement around the vehicle, while the 0–88.5 ft-lbs maximum forward torque gives the operator a defined forward torque output. The CP8854-2K weighs 5.73 lb with its battery configuration and measures 9.41" in length, with a 1/2" square drive and friction-ring socket retention. The specified 9.3 m/s² vibration level and 87 dB(A) sound pressure provide measurable operating characteristics for tire and vehicle service environments.

FAQs:
- Q: What is the maximum torque of the CP8854-2K?
A: The specified maximum reverse torque is 774 ft-lbs. Maximum reverse torque is the tool's loosening output rather than its normal forward tightening torque. - Q: What is the forward torque of the CP8854-2K?
A: The specified maximum forward torque is 88.5 ft-lbs. - Q: What is the difference between the CP8854-2K and the standard CP8854K?
A: The CP8854-2K uses the CP8854 platform with a 2" extended anvil, while the standard CP8854K uses the standard anvil configuration. The CP8854-2K is also supplied as a kit with two 18V 2.5 Ah batteries and a charger. - Q: What type of impact mechanism does this wrench use?
A: The CP8854-2K uses a twin hammer impact mechanism, which delivers repeated hammer impacts to the anvil during operation. - Q: What battery does the CP8854-2K use?
A: The kit uses 18V 2.5 Ah lithium-ion batteries. - Q: How many batteries are included?
A: Two 18V 2.5 Ah lithium-ion batteries are included with the CP8854-2K kit, along with a charger. - Q: What is the free speed?
A: The CP8854-2K has a specified free speed of 4,500 RPM. - Q: What is the purpose of the two-stage trigger?
A: The two-stage forward trigger provides a snugging function for initial fastener rundown, helping reduce the need to start lug nuts or similar fasteners by hand. - Q: Does the CP8854-2K require compressed air?
A: No. It is a cordless electric impact wrench powered by an 18V lithium-ion battery system, so an air hose and compressor are not required for operation.
