1/4 in NPT Pistol-Grip Impact Wrench
The SPEEDAIRE 21AA50 is an air-powered impact wrench with a 1/4 in NPT female inlet. It delivers 600 ft-lb of breakaway and fastening torque at a free speed of 9,000 RPM and 1,200 impacts per minute. The tool operates between 50 psi and 90 psi while consuming 17 cfm of air.
Suited for general-duty fastening up to 5/8 in bolts
Five speed settings give control over a range of assembly and maintenance tasks. The bottom exhaust directs air away from the work area. Buyers needing a tool rated for explosive environments or a different drive size should look elsewhere. A minimum 3/8 in hose is required for proper airflow.
600 ft-lb torque capacity with 9,000 RPM free speed
This output handles most heavy-duty lug nuts and structural bolts within the 5/8 in capacity. Sustained operation at the top end demands a compressor that can maintain 90 psi and 17 cfm continuously. The 96 dB sound level means hearing protection is advisable during extended use.

Questions about this item
What size air compressor and hose do I need to run the SPEEDAIRE 21AA50 at its 17 cfm air consumption?
You need a compressor that can deliver at least 17 cfm at 90 psi and a hose with a minimum 3/8 in inside diameter.
Will the 1/4 in NPT air inlet on this wrench connect to the fittings on my older 3/8 in hose?
The tool has a 1/4 in NPT female inlet, so you will need a 1/4 in NPT male fitting on the hose or an adapter to join the two sizes.
How can I confirm the wrench is producing its rated 600 ft-lb breakaway torque after I hook it up?
Set the regulator to 90 psi, select the highest speed setting, and verify the tool reaches 9,000 rpm free speed and 1,200 impacts per minute under load.
