Ingersoll Rand 2920B1 Heavy Duty Air Impact Wrench combines a 3/4" square drive with 5,000 RPM free speed and up to 1,100 ft-lbs of maximum torque for substantial fastening and fastener removal work. Its 3/4" drive size provides compatibility with appropriately sized impact sockets used on larger threaded connections in industrial maintenance, machinery service, fleet repair, and equipment maintenance applications.
For technicians who need more socket capacity and torque than smaller pneumatic impact wrenches provide, the 2920B1 offers a practical combination of 1,100 ft-lbs maximum torque and 5,000 RPM free speed. The higher free-speed rating supports efficient fastener rundown, while the impact action provides repeated rotational force as resistance increases during tightening or removal.
Type: Air Impact Wrench | Model: 2920B1 | Drive Size: 3/4" | Drive Type: Square | Free Speed: 5,000 RPM | Maximum Torque: 1,100 ft-lbs

Tech Tip: To increase tool performance, extend tool life, and lessen repair costs, use it with a Filter-Regulator-Lubricator FRL)
Applications:
- Industrial maintenance and MRO: installing and removing larger fasteners on machinery and mechanical assemblies.
- Fleet and equipment service: handling 3/4" drive fastening tasks on commercial vehicles and service equipment.
- Heavy machinery repair: working with substantial threaded connections that require greater torque capacity than smaller impact tools provide.
- Manufacturing support: performing recurring pneumatic fastening and removal tasks involving larger bolted assemblies.
- Field maintenance: supporting large-fastener service work where compatible impact sockets and an adequate compressed-air supply are available.
FAQs:
- Q: What drive size does the Ingersoll Rand 2920B1 use?
A: The 2920B1 uses a 3/4" square drive. It should be paired with compatible 3/4" drive sockets specifically rated for impact wrench operation. - Q: What is the maximum torque rating of the 2920B1?
A: The supplied manufacturer catalog information identifies the tool with a maximum torque rating of 1,100 ft-lbs. - Q: What does the 5,000 RPM specification mean?
A: The 5,000 RPM figure is the listed free speed, meaning the rotational speed of the impact wrench while operating without a fastening load. - Q: Can standard hand-tool sockets be used with the 2920B1?
A: Use 3/4" drive sockets specifically rated for impact use. Standard hand sockets are not intended for repeated loading from a pneumatic impact wrench. - Q: What should be checked before selecting the 2920B1?
A: Confirm that the 3/4" square drive matches the required impact tooling and that the available compressed-air system is appropriately sized for the tool.
