Ingersoll Rand 1077XPA Standard Air Ratchet Wrench features a 1/2" square drive and delivers up to 54 ft-lbs (73 Nm) of maximum torque for automotive repair, equipment servicing, and general maintenance. With a 160 RPM free speed, this pneumatic ratchet helps technicians install and remove threaded fasteners efficiently, particularly in confined areas where manual ratcheting can be time-consuming.
Designed for durability and convenient handling, the 1077XPA incorporates an advanced, heat-treated ratchet head and a variable-speed lever throttle for controlled operation. Its adjustable power regulator helps operators manage tool output, while the 360-degree adjustable exhaust allows discharged air to be directed away from the work area. The 10–45 ft-lbs (14–61 Nm) recommended torque range provides a useful reference for selecting appropriate fastening applications.

FAQs:
- Q: What is the maximum torque of the Ingersoll Rand 1077XPA?
A: The 1077XPA delivers up to 54 ft-lbs (73 Nm) of maximum torque. Ingersoll Rand specifies a recommended torque range of 10–45 ft-lbs (14–61 Nm). - Q: What is the difference between the 1077XPA and 107XPA?
A: The primary difference is drive size. The 1077XPA uses a 1/2" square drive, while the 107XPA uses a 3/8" square drive. Both models have a maximum torque rating of 54 ft-lbs and a free speed of 160 RPM. - Q: Can the 1077XPA be used in confined spaces?
A: Yes. Its narrow ratchet configuration provides reach for fasteners located around closely spaced components, making it useful for automotive and maintenance applications. - Q: Does the 1077XPA offer adjustable speed and power?
A: Yes. The tool features a variable-speed lever throttle and an adjustable power regulator, allowing the operator to manage rotation speed and tool output. - Q: Can the exhaust direction be changed?
A: Yes. The 360-degree adjustable exhaust can be positioned to direct discharged air away from the operator and work area. - Q: What compressed-air connection does the 1077XPA require?
A: Ingersoll Rand specifies a 1/4" NPTF air inlet and a minimum 3/8" (10 mm) hose size. Average air consumption is 4 CFM (113 L/min), with 19 CFM (538 L/min) specified at free speed.
