Built for general maintenance and fastening applications, the Chicago Pneumatic CP7741 Pneumatic Impact Wrench combines a 1/2" square drive with a 10,000 RPM free speed and 715 ft-lbs maximum reverse torque. Its twin hammer impact mechanism provides the specified impact configuration, while the composite housing helps reduce heat transfer between the motor and handle.
The CP7741 delivers a 120–690 ft-lbs forward working torque range and is designed around operator comfort, with a lightweight composite construction and compact 7.64" overall length. The manufacturer specifically notes that the CP7741 weighs 2.25 kg (4.96 lb) and is 15% lighter than its former version.
