SPEEDAIRE 21AA80 Air Screwdriver

The SPEEDAIRE 21AA80 is an in-line pneumatic screwdriver built for assembly and fastening tasks that require controlled torque. It accepts 1/4 in hex bits through a quick-change chuck and operates from a standard 1/4 in NPT air inlet. The reversible lever throttle lets the operator switch direction without changing grip.

Sustained-load torque and air consumption

At the required 90 psi the tool delivers a maximum torque of 8 ft-lb with a soft-draw range of 30 to 95 in-lb. Under continuous operation it draws 16.0 CFM, while a 15-second burst averages 4.00 CFM. The free speed of 800 RPM is rated for general-duty cycles rather than high-volume production runs.

In-line body, quick-change chuck and hose sizing

The 10 1/4 in overall length keeps the centre of gravity close to the hand for steady control during extended use. A minimum 3/8 in hose is specified to maintain pressure at the 1/4 in NPT inlet. The adjustable clutch and reversible lever are integrated into the slim body, so there are no external protrusions to catch on workpieces or bench edges.

Questions about this item

How loud or hot does the SPEEDAIRE 21AA80 get when running continuously at 800 RPM?

The tool consumes 4.00 CFM average at a 15-second run time and 16.0 CFM at full load, so sustained use demands a compressor that can maintain 90 psi without overheating.

What compressor fittings and hose must I already have to operate this 1/4 in NPT air screwdriver?

You need a 1/4 in NPT air inlet connection, a minimum 3/8 in hose, and a supply capable of 90 psi to meet the 4.00 CFM average and 16.0 CFM full-load requirements.

Will the 1/4 in hex quick-change chuck on this in-line driver accept the bits I already use with my older pneumatic tools?

Yes, the 1/4 in hex quick-change chuck is an industry-standard interface, so existing 1/4 in hex bits fit directly without adapters.
