Overview
Ingersoll Rand builds this air impact wrench around a cold-forged twin-hammer mechanism in a steel hammer case, turning a large square drive for heavy fasteners. A built-in pressure gauge helps tune the air supply, and Quiet Technology lowers the noise.
Truck shops and equipment mechanics get heavy torque in a pistol-grip body made for confined bolt access. The torque figure differs between the bullets and the spec table, and the compressor and hose are not part of the purchase.
Who it's for
Fleet mechanics, heavy equipment techs and MRO crews breaking large fasteners on trucks and machines will use the full drive size. Home mechanics working on cars with a small compressor should look at a smaller-drive tool.
Pros and cons
- Big drive for heavy fasteners
- Built-in pressure gauge
- Quiet Technology reduces noise
- One-hand forward and reverse
- Torque figures conflict within the listing
- Air consumption not listed
- Bare tool, no sockets
Performance notes
Output comes from the twin-hammer mechanism powered by a six-vane motor on compressed air, so delivered force depends on supply pressure and flow. The pressure gauge lets the user confirm the supply is set for full output. Quiet Technology reduces noise for work in sensitive environments.
