Product Number: 6151800110
The Chicago Pneumatic CP6641 delivers exceptional controlled torque output for heavy-duty industrial fastening applications where precision and raw power are non-negotiable. Engineered for demanding assembly and maintenance environments, this 1-inch drive stall torque nutrunner produces an impressive 4,100 Nm of maximum torque in both forward and reverse, making it one of the most capable chicago pneumatic impact wrench solutions available for large-fastener applications. Built around a stall-type torque control system, the CP6641 provides consistent and repeatable results without electronic feedback, keeping the tool mechanically robust and straightforward to maintain on the shop floor. A free speed of 10 RPM ensures the tool drives fasteners at a controlled pace appropriate for high-torque assembly, while the minimum torque threshold of 1,000 Nm still represents serious clamping force for even the most demanding joints. The 1-inch square drive offers compatibility with heavy industrial sockets, making it the natural choice where a standard cp impact wrench or air impact wrench simply cannot deliver sufficient output. Constructed to Chicago Pneumatic's exacting standards, the CP6641 is designed for long service intervals and consistent performance under continuous production conditions. Facilities assembling heavy machinery, structural steel, mining equipment, rail rolling stock, or large commercial vehicles will find this nutrunner an indispensable tool for achieving precise, high-torque joints with confidence and repeatability every cycle.Product Feature: Compact tool for tight high torque application Industrial FRL ATC pack for high accuracy Vane type impact wrench air motor for high performance Lightweight, swivelling handle and one-finger reverse mode for high operator comfort 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.
