SPEEDAIRE 21AA81 air screwdriver
The SPEEDAIRE 21AA81 is a new in-line air screwdriver built for general-duty fastening. It delivers a soft-draw torque range of 30 to 70 in-lb and a maximum torque of 5.8 ft-lb at a free speed of 1,800 RPM. The tool connects via a 1/4 in NPT air inlet and accepts 1/4 in hex quick-change bits for rapid swaps.
Suited for assembly lines
This tool suits operators who require reversible, lever-throttle control with an adjustable clutch for consistent results. It is not intended for buyers who need higher torque output, a pistol-grip form factor, or a precision shut-off clutch for critical torque-critical joints.
Quick-change chuck and lever throttle improve
The 1/4 in hex quick-change chuck reduces bit-change downtime during repetitive tasks. The lever throttle provides featherable speed control, while the reversible function allows both tightening and loosening without removing the tool from the workpiece.

Questions about this item
What compressor output and hose size do I need to run this 1800 RPM air screwdriver?
It requires 90 psi supply pressure, a minimum 3/8 in hose, and consumes 4.00 CFM average at 15 second run time or 16.0 CFM at full load.
Will my existing 1/4 in hex bits fit the quick-change chuck on this tool?
Yes, the chuck accepts standard 1/4 in hex bits with quick-change action.
How can I verify the adjustable clutch is delivering torque within the 30 to 70 in-lb range after setup?
Test on a calibrated torque checker or known fastener joint; the clutch should slip consistently between 30 and 70 in-lb (max 5.8 ft-lb).
