Ingersoll Rand 1077XPA Air Ratchet 1/2 in Drive

Product Description

The INGERSOLL RAND 1077XPA is a pneumatic air ratchet built for professional mechanics and industrial technicians who need reliable torque in tight spaces. It runs on compressed air through a 1/4 inch NPTF inlet, consumes 4 CFM at operating pressure, and delivers up to 53.84 ft-lb of torque through a 1/2 inch square drive. The inline handle design keeps the tool compact and well-balanced for extended use in confined areas. Variable speed control gives the operator precise control over fastener seating, reducing the risk of over-torquing. At 3.14 pounds and 10 inches in overall length, it is sized for engine bay, underbody, and equipment maintenance work.

This air ratchet is suited for automotive repair shops, fleet maintenance facilities, and industrial assembly lines where 1/2 inch drive fasteners are common. The 1/4 inch NPTF air inlet connects to standard shop air supply lines. A minimum hose size of 5/16 inch is required to maintain adequate airflow. Working torque range is 10 to 48 ft-lb, covering most standard bolt and nut sizes up to 3/8 inch bolt capacity. The tool operates at 160 RPM free speed, making it efficient for both run-down and final snugging tasks.

Installation Notes

This tool is installed and operated by automotive technicians and industrial mechanics. Before connecting to a compressed air supply, verify that the air line pressure matches the tool's rated operating range and that the supply hose meets the minimum 5/16 inch diameter requirement. Always disconnect the air supply before changing sockets or performing any maintenance on the tool. Follow shop safety protocols and applicable OSHA compressed air tool handling guidelines when operating pneumatic equipment.
