Ingersoll/Rand 772 Air Hammer
The Ingersoll/Rand 772 is a heavy-duty air hammer designed for concrete work. It delivers 3,000 blows per minute with a 2 1/4 inch stroke length. The tool accepts a 0.401 inch round shank and uses a chisel retainer. It operates on compressed air at 90 psi.
Suited for demolition and concrete removal
This pistol-grip hammer fits technicians who need high-impact force for breaking concrete. It requires a 15 cfm air supply and a minimum 3/8 inch hose. Buyers without a compressor meeting that flow should look at electric alternatives. The bare tool ships without chisels or a kit.
Sustained operation at rated pressure
At 90 psi the hammer maintains its 3,000 bpm rate as long as the compressor supplies 15 cfm continuously. Air consumption stays steady during extended demolition runs. The 1/4 inch FNPT inlet keeps the connection secure under vibration. Performance drops if the air supply falls below the rated flow.

Questions about this item
What air compressor capacity do I need to run the 772 at its rated 15 cfm?
You need a compressor that can deliver at least 15 cfm continuously at 90 psi so the hammer maintains 3,000 bpm without pressure drop.
Will my existing 3/8 in air hose work with the 1/4 in NPT female inlet on this tool?
Yes — the inlet is 1/4 in NPT female and the minimum hose size is 3/8 in, so your hose connects with a standard 1/4 in NPT male fitting.
How can I confirm the 772 is hitting its full 3,000 blows per minute after hooking it up?
Listen for a steady, rapid chatter at the chisel; a noticeable slowdown means pressure is below 90 psi or the hose is restricting flow.
