Delivering exceptional cordless performance without compromise, the Chicago Pneumatic CP8641 PACK redefines what professionals expect from a battery-powered torque wrench. Engineered for demanding industrial and automotive environments, this 36V 1-inch drive battery torque wrench generates an impressive 470 Nm of maximum torque, giving technicians the raw power needed to tackle the toughest fastening and removal tasks with confidence. Unlike a traditional pneumatic impact wrench that requires a compressor and airline, the CP8641 PACK runs on a robust 36V 2.5Ah lithium-ion battery, delivering true cordless freedom across workshops, job sites, and remote locations. The tool maintains exceptional control and precision throughout its torque range, making it a compelling alternative to conventional chicago pneumatic impact wrench models in applications where mobility matters. Operator comfort is taken seriously in the CP8641's design. Sound power levels are kept below 72 dB(A), with a measured sound power of just 66 dB(A) and sound pressure of 83 dB(A), significantly reducing fatigue during prolonged use. Vibration is also tightly controlled at under 2.5 m/s², meeting ergonomic standards that protect operators over long shifts. Maximum ambient storage temperatures ensure the battery retains performance across varied climates. This cp impact wrench is ideally suited for heavy vehicle maintenance, truck and bus workshops, agricultural machinery servicing, and construction equipment repair where high torque output, low noise, and total portability are essential daily requirements.Product Feature: High precision with +/- 4% Safe tightening with second start button as standard Extended mobility with lightweight and compact battery Automatic release reaction arm Intuitive handling either on OLED Digital screen of the tool or via CPLinQ app About MachineRefurb: MachineRefurb is an e-commerce platform specialising in replacement parts, spares and consumables for construction, agriculture and industrial machinery, serving customers across Ireland, the United Kingdom and Europe.
