This professional-grade tool delivers robust performance and extended reach, making it a reliable choice for fleet maintenance and high-volume tire service operations where consistent torque is critical.

Key Features

• Extended Reach: The 1" drive with a 6" extended anvil is specifically designed to access deep-set wheel studs and dual wheels on Class 6–8 trucks, buses, trailers, and agricultural equipment, streamlining wheel service by eliminating the need for multiple extensions.
• High-Torque Performance: Provides up to 1300 ft-lbs of reverse torque (1760 Nm) and 250–1070 ft-lbs working forward torque (340–1450 Nm), offering ample power for stubborn, corroded fasteners and intensive wheel work.
• Durable Construction: Features a heavy-duty, pinless, closed reinforced rocking dog mechanism within an aluminum clutch housing and steel motor, ensuring a long service life in demanding industrial MRO and fleet environments.
• Ergonomic Control: Equipped with an inside trigger D-handle and a soft-touch side handle that swivels into four positions, enhancing control in various orientations. A 4-position power regulator, accessible from both sides, allows for quick adjustments to suit fastener size, material, and required torque.
• Operator-Focused Design: Downward exhaust directs air away from the user, while integrated rubber bumpers help protect both the tool and finished surfaces from damage during use.

Applications
