Chicago Pneumatic expands its pneumatic torque wrench portfolio CP66 with the new CP6681. Compact, robust, and designed for demanding industrial applications, the CP6681 features an ergonomic D-Handle that enhances operator comfort and control, while delivering the durability and performance required for critical bolting operations.
CP6681: high‑durability pneumatic design for high torque bolting applications
Industrial bolting tasks require tools that can withstand harsh environments while remaining easy and comfortable to operate. Designed with these needs in mind, the CP6681 combines a compact form factor with a rugged construction, making it suitable for tightening operations across Oil & Gas, Mining & Heavy Industry, and Steel Construction & Infrastructure.
Operating at 10 RPM at maximum torque, the CP6681 delivers both productivity and tightening accuracy of ±5%, further enhanced when equipped with the optional ATC pack. Its pneumatic design eliminates overheating and ensures consistent power output during intensive use.
Improved bolting operator comfort with an ergonomic D‑handle
A standout feature of the CP6681 is its ergonomic D‑Handle. Engineered to provide a secure and comfortable grip, it improves tool control and helps reduce operator fatigue during repetitive bolting tasks.
This ergonomic approach is especially valuable in challenging environments where operators spend extended periods performing tightening operations. By improving handling and comfort, the CP6681 contributes to a safer and more efficient working experience.
