Overview
Ingersoll Rand 2906P1 Super Duty Air Impact Wrench combines a 1/2" square drive with a 5,000 RPM free speed and 500 ft-lbs of maximum reverse torque for fastening and removal work on automotive, equipment, fabrication, and maintenance applications. Its 40–350 ft-lbs forward torque range provides a useful tightening range, while the higher reverse rating supplies additional force for breaking loose stubborn fasteners. The pistol-grip, trigger-actuated configuration keeps the controls familiar for technicians using the tool in service environments. The 2906P1 uses a twin hammer mechanism (two hammers that deliver balanced impacts to the anvil) and a steel hammer case to handle repeated impact cycles. Its pin-retainer square drive provides positive socket retention, while pressure-fed mechanism lubrication and an integral muffler are part of the 2900 Series configuration. At 6.88" long and 6 lbs without a socket, the tool provides substantial torque in a relatively compact 1/2" drive package. Type: Air Impact Wrench | Series: 2900 Series | Configuration: Pistol | Actuation: Trigger | Drive Size: 1/2" | Drive Type: Square, Pin | Impact Mechanism: Twin Hammer | Free Speed: 5,000 RPM | Blows Per Minute: 1,200 | Maximum Reverse Torque: 500 ft-lbs (678 Nm) | Forward Torque Range: 40–350 ft-lbs (54–475 Nm) | Weight: 6 lbs (2.72 kg) | Length: 6.88" (175 mm) | Side to Center: 1.34" (34 mm) | Air Inlet: 1/4" NPT | Minimum Hose Size: 3/8" | Air Consumption: 23 CFM (651 L/min) | Vibration: 7.6 m/s² Features: Twin hammer mechanism delivers balanced impact action for repeated fastening and removal cycles Steel hammer case and metal housing provide a durable enclosure for the impact mechanism 1/2" square pin drive securely retains compatible impact sockets during service work Pressure-fed mechanism lubrication supplies lubricant to the impact mechanism during operation Integral muffler helps manage exhaust noise from the pneumatic motor Trigger actuation provides direct control over tool operation Compact 6.88" length helps technicians work around vehicle components and other restricted areas Tech Tip: To increase tool performance, extend tool life and lessen repair costs use it with a Filter-Regulator-Lubricator (FRLs) Applications: Automotive service — removing and installing wheel, suspension, brake, and chassis fasteners within the tool's torque range. Fleet and equipment maintenance — servicing medium-size machinery and vehicle assemblies with compatible 1/2" drive sockets. Industrial maintenance — fastening and removing threaded hardware on machinery and mechanical assemblies. Fabrication and repair — handling repetitive bolting tasks where pneumatic impact action reduces manual effort. General shop service — tightening and loosening fasteners across maintenance and repair work where a 1/2" square drive is appropriate. FAQs: Q: What is the difference between the 350 ft-lbs forward torque and 500 ft-lbs maximum reverse torque?A: The 350 ft-lbs figure is the maximum forward torque specified for tightening, while 500 ft-lbs is the maximum reverse torque available for loosening fasteners. The published forward working range is 40–350 ft-lbs. Q: What sockets fit the 2906P1?A: The tool uses a 1/2" square drive with a pin-retainer configuration, so use compatible 1/2" drive impact sockets designed for the appropriate retaining arrangement. Q: What does the twin hammer mechanism do?A: A twin hammer mechanism uses two hammers to deliver balanced impacts to the anvil, providing the repeated impact action used to tighten and remove threaded fasteners. Q: What air supply does the 2906P1 require?A: The catalog specifies 23 CFM average air consumption, a 1/4" NPT air inlet, and a minimum 3/8" hose size. The available air system should be sized to maintain suitable pressure and flow at the tool. Q: Is the 2906P1 suitable for general automotive work?A: Yes. Its 1/2" driv…
