Designed for light-vehicle tire changing in workshops and roadside assistance, the Chicago Pneumatic CP8854 Cordless Impact Wrench combines a 1/2" square drive, 4,500 RPM free speed, and 774 ft-lbs maximum reverse torque in a portable cordless configuration. Its 0–88.5 ft-lbs forward working torque, twin hammer impact mechanism, and brushless motor provide the specified fastening and removal performance without requiring a pneumatic hose.
The CP8854 is the bare-tool configuration and does not include batteries or a charging station. It accepts the manufacturer's 18V 2.5 Ah lithium-ion battery system, which is available separately. A built-in forward shut-off position helps prevent overtightening, while the two-stage forward trigger provides a snugging function intended to reduce the need for hand tightening. The compact 7.44" length and 4.63 lb weight without battery provide the specified cordless format for mobile vehicle service.
