Ingersoll Rand 261 3/4-In. Square Impactool Pistol – 1,100 ft-lb Max Torque
Product Overview
The Ingersoll Rand 261 3/4-In. Square Impactool Pistol Impact Wrench is a heavy-duty pneumatic tool designed for demanding automotive, truck, machinery, and industrial maintenance applications. Its 3/4-inch square drive and 1,100 ft-lb maximum reverse torque provide substantial power for removing stubborn fasteners and handling larger fastening jobs.
The 261 combines a six-vane air motor with Ingersoll Rand's Jumbo Hammer impact mechanism, providing strong torque output while maintaining a relatively compact pistol-grip design. A pressure-fed lubrication system is designed to support reliable operation and extended tool life.
Key Features
- 3/4-inch square drive for heavy-duty impact sockets.
- 1,100 ft-lb maximum reverse torque.
- Approximately 200–900 ft-lb working torque range.
- 5,500 RPM free speed.
- 1,000 impacts per minute.
- Six-vane high-torque air motor.
- Jumbo Hammer impact mechanism.
- Pistol-grip configuration with trigger actuation.
- Square hog-ring socket retention.
- Pressure-fed lubrication system.
- Handle exhaust directs exhaust air away from the operator.
- 3/8-inch NPT air inlet.
- Recommended minimum 1/2-inch air hose.
1,100 ft-lb Maximum Torque
The 261 is designed for high-torque fastening and removal work. Its 1,100 ft-lb maximum reverse torque gives technicians substantial power for loosening stubborn fasteners.
Typical applications include:
- Heavy truck repair
- Vehicle maintenance
- Construction machinery
- Agricultural equipment
- Machinery repair
- Fleet service
- Industrial maintenance
- Engine teardown work
The manufacturer also identifies the 261 series as suitable for vehicle repair and heavy truck and machinery applications.
Important: Maximum reverse torque is not the same as a calibrated tightening torque. For safety-critical fasteners, always use the equipment manufacturer's specified torque and a calibrated torque wrench for final tightening when required.
Jumbo Hammer Mechanism
The Jumbo Hammer mechanism is designed to provide high torque output and maintain performance when air pressure changes during operation. Ingersoll Rand lists the 261 with a maximum reverse torque of 1,100 ft-lb and a working torque range of approximately 200–900 ft-lb.
This makes the impact wrench well suited to applications where repeated high-impact performance is required.
Six-Vane Air Motor
The six-vane pneumatic motor is designed to provide strong torque output from compressed air.
The tool reaches a free speed of approximately 5,500 RPM, while its impact mechanism produces about 1,000 blows per minute.
Actual performance depends on the air pressure and airflow available at the tool.
3/4-Inch Square Drive
The 3/4-inch square drive is designed for compatible heavy-duty impact sockets.
This drive size is particularly useful for larger fasteners found on trucks, machinery, equipment, and other applications where a 1/2-inch impact wrench may not provide sufficient capacity.
The hog-ring socket retention system helps secure compatible sockets to the square drive.
Professional Applications
Heavy Truck & Fleet Service
The 261 is well suited to commercial vehicle maintenance, including work on trucks, trailers, and other fleet equipment.
Machinery Maintenance
Its high torque capacity makes it useful for removing large or stubborn fasteners on machinery and equipment.
Automotive Repair
The tool can handle larger automotive repair tasks where a 3/4-inch drive is appropriate.
Engine & Equipment Work
Ingersoll Rand specifically highlights applications such as spring work, pinion nut removal, track-pad removal, and major engine teardowns.

Air Supply Requirements
The 261 is a pneumatic tool and requires an adequate compressed-air system for proper performance.
It uses a 3/8-inch air inlet, with a 1/2-inch minimum hose size specified by Ingersoll Rand. Average air consumption is approximately 9.5 CFM, while consumption under load can reach approximately 38 CFM.
For best results:
- Use a properly sized compressor.
- Maintain approximately 90 PSI at the tool.
- Use a suitable 1/2-inch or larger air hose.
- Avoid restrictive fittings and couplers.
- Check hoses and connections for leaks.
- Keep the compressed-air supply clean and properly conditioned.
Ergonomic Exhaust Design
The 261 incorporates a handle exhaust that directs exhaust air away from the operator rather than directly toward the work area or user's hands. This is useful when the tool is being used repeatedly in a professional environment.
Maintenance
Proper maintenance helps preserve the tool's torque output and extend service life.
Recommended practices include:
- Lubricate the tool according to Ingersoll Rand's instructions.
- Maintain clean, properly conditioned compressed air.
- Inspect the air inlet and fittings regularly.
- Check the hog ring and square drive for wear.
- Use only impact-rated sockets.
- Keep the tool clean.
- Inspect for unusual noise, vibration, or air leakage.
- Service internal components as recommended by the manufacturer.
The 261 uses a pressure-fed lubrication system, designed to support long-term performance.
Proper Fastening Technique
The 261 is intended to quickly install and remove fasteners, but its maximum torque should not be used as a substitute for calibrated torque measurement.
For critical fasteners:
- Use the impact wrench to run the fastener into position.
- Avoid relying on impact duration as an exact torque measurement.
- Finish tightening with a calibrated torque wrench when required.
- Follow the equipment manufacturer's torque specification.
This is especially important for wheel assemblies, suspension components, structural fasteners, and other safety-critical connections.
Safety Considerations
Because the 261 can produce more than 1,000 ft-lb of reverse torque, appropriate safety practices are essential.
- Wear eye and hearing protection.
- Use only impact-rated sockets.
- Do not use cracked or damaged sockets.
- Keep hands away from the rotating drive.
- Secure the workpiece before applying torque.
- Disconnect the air supply before servicing.
- Do not exceed the recommended air pressure.
- Follow the manufacturer's operating instructions.
- Use proper torque-control procedures for critical fasteners.
