Air-powered ratchet with 3/8 in drive delivers 150 RPM free speed and 50 ft-lb torque at 90 psi operating pressure
- Delivers 50 ft-lb torque for tough fasteners
- Free speed of 150 RPM speeds up jobs
- Compact 10 in length fits tight spaces
- Lightweight 2.5 lb design reduces operator fatigue
- 3/8 in drive accepts common sockets
Tool purpose and user fit
The SPEEDAIRE 21AA64 is an air-powered ratchet with a 3/8 in drive and 150 RPM free speed. It suits mechanics and technicians who need a compact tool for general-duty fastening in tight spaces where a larger impact wrench would not fit.
Capacity and headroom
The ratchet delivers 50 ft-lb of fastening torque and consumes 16 cfm at 90 psi operating pressure. It requires a minimum hose size of 3/8 in and inlet pressure between 50 and 90 psi. Heavy-duty bolts or high-torque applications will exceed its capacity.
Thermals noise and power draw
The tool exhausts through a bottom port to direct air away from the work area. At 2.5 lb and 10 in overall length it remains light for extended use. Air consumption of 16 cfm means the compressor must supply adequate flow to maintain speed under load.

Questions about this item
Will the 1/4 in NPT air inlet connect directly to the 3/8 in hose I already use in my shop?
The tool has a 1/4 in NPT female inlet and the specs call for a minimum 3/8 in hose, so you will need a 1/4 in NPT to 3/8 in hose fitting or coupler to join them.
How can I verify the ratchet is delivering the rated 150 RPM and 50 ft-lb torque once I hook it up?
Run it at 90 psi with a 3/8 in hose; the free speed should reach 150 RPM and the fastening torque will hit 50 ft-lb under load — if it feels sluggish, check that supply pressure is not below 50 psi.
Does the box include any sockets, air hose or fittings, or do I need to buy them separately?
Only the ratchet itself is listed — drive size 3/8 in, ball-detent retainer, 10 in overall length, 2.5 lb — so sockets, a 3/8 in minimum hose and a 1/4 in NPT fitting must be purchased separately.
