Ingersoll Rand 261-6 Air Impact Wrench | 3/4" Drive Size | 5500 RPM | 1,100 (ft-lbs) Max Torque

For commercial truck wheel service and heavy machinery maintenance where fasteners are positioned deep inside assemblies, the Ingersoll Rand 261-6 Pistol Grip Pneumatic Impact Wrench provides extended reach and substantial fastening power. Featuring a 3/4-inch square drive with a 6-inch extended anvil, this air impact wrench allows technicians to reach recessed wheel nuts and mechanical fasteners that may be difficult to access with shorter tools. Ingersoll Rand's current specifications list 1,100 ft-lbs (1,491 Nm) of forward torque and 1,200 ft-lbs (1,627 Nm) of maximum reverse torque for loosening resistant fasteners. Its 5,500 RPM free speed supports rapid fastener rundown, while the 1,000 blows per minute (BPM) impact rate provides repeated rotational impacts for large fastening and removal operations.

The Ingersoll Rand 261-6 incorporates a jumbo hammer impact mechanism, which uses a large hammer to transfer rotational impact energy to the output drive. This mechanism provides a favorable power-to-weight ratio and straightforward maintenance, while the vane motor delivers the pneumatic power required for vehicle and machinery service. A power regulator allows operators to adjust output for different fastening tasks, and the hog-ring socket retainer (a friction ring that helps hold the socket on the square drive) supports secure engagement with compatible impact sockets. Measuring 14.8 inches (376 mm) in overall length and weighing 13.7 lbs (6.21 kg), the 261-6 offers greater reach than both the standard-anvil 261 and the 3-inch extended-anvil 261-3. Its 3/8-inch air inlet and 1/2-inch minimum hose size provide the connection specifications needed when selecting a compressed-air system for heavy vehicle and industrial maintenance operations.

Tech Tip: To increase tool performance, extend tool life and lessen repair costs use it with a Filter-Regulator-Lubricator (FRLs)

Applications:

• Commercial truck and trailer maintenance involving recessed wheel nuts and other large vehicle fasteners requiring extended anvil reach.
• Heavy equipment repair involving large bolts on construction machinery, agricultural equipment, and mechanical assemblies.
• Fleet service operations requiring pneumatic fastener removal during scheduled maintenance and commercial vehicle repairs.
• Industrial plant maintenance involving machinery disassembly, equipment servicing, and large bolted connections.
• Truck tire service facilities working with deep wheel configurations where a standard-anvil impact wrench cannot conveniently reach the fastener.

FAQs:

• Q: What is the difference between the Ingersoll Rand 261, 261-3, and 261-6?
  A: The primary difference is anvil length. The 261 has a standard anvil and measures 8.8 inches overall, the 261-3 has a 3-inch extended anvil and measures 11.8 inches, and the 261-6 has a 6-inch extended anvil and measures 14.8 inches. All three models use a 3/4-inch square drive and share the same current manufacturer torque ratings.
• Q: Does the Ingersoll Rand 261-6 deliver 1,100 or 1,200 ft-lbs of torque?
  A: Ingersoll Rand's current manufacturer specifications list 1,100 ft-lbs (1,491 Nm) of forward torque and 1,200 ft-lbs (1,627 Nm) of maximum reverse torque. Some older product literature describes 1,100 ft-lbs as maximum torque. The current direction-specific ratings should be used when comparing the 261-6 with other impact wrenches.
• Q: What air compressor is required for the Ingersoll Rand 261-6?
  A: The manufacturer specifies 38 CFM air consumption at load, 9.5 CFM average air consumption, and 90 PSI operating pressure. The tool uses a 3/8-inch air inlet and requires a minimum 1/2-inch air hose. Select a compressed-air system capable of maintaining the required airflow and pressure during the intended duty cycle.
• Q: Can the 261-6 be used for deep truck wheel nuts?
  A: Yes. The 6-inch extended anvil provides additional reach for accessing recessed wheel fasteners on suitable commercial truck and trailer assemblies. Actual accessibility depends on wheel geometry, socket dimensions, and surrounding clearance. Always verify final wheel-fastener torque with a calibrated torque wrench.
• Q: What sockets are compatible with the Ingersoll Rand 261-6?
  A: The 261-6 uses a 3/4-inch square drive with hog-ring socket retention. Select compatible 3/4-inch drive impact-rated sockets and verify the retaining arrangement before use. Standard hand-tool sockets should not be used with pneumatic impact wrenches.
