SPEEDAIRE 21AA78 3/8 Inch Air Drill
The SPEEDAIRE 21AA78 is a pneumatic inline drill designed for automotive and general workshop tasks. It operates at a free speed of 22000 RPM with a torque rating of 0.50 ft-lb. The tool requires a minimum 3/8 inch hose and 90 psi operating pressure. It is suited for technicians needing a lightweight, variable-speed drill for precision fastening and drilling applications.
Sustained load performance at 16 CFM
Under continuous operation the drill draws 16.0 CFM at full load while averaging 4.00 CFM during a 15 second run interval. The ball-bearing construction and aluminum housing help maintain consistent speed when driving fasteners into harder materials. Lever throttle control allows the operator to modulate power without sudden torque spikes. Aluminum handle material reduces vibration transfer during extended use.
Installation and common issues
Connection is straightforward using a standard 3/8 inch air hose at 90 psi supply pressure. The inline body style fits directly into tight work areas without a right-angle offset. Variable speed lever throttle engages smoothly but requires clean, dry air to prevent internal contamination. California Proposition 65 warnings indicate the product contains chemicals known to cause cancer and reproductive harm; appropriate personal protective equipment should be worn.

Questions about this item
How much air does the 22,000 RPM drill consume when running continuously at full load?
At full load the drill draws 16.0 CFM at 90 psi, so a compressor that can sustain that flow is needed for all-day use.
What minimum hose size and pressure must my compressor deliver for the 3/8 in drill to operate correctly?
The tool requires a 3/8 in hose and 90 psi at the inlet; anything smaller or lower will starve the motor.
Will the 1.7 lb aluminum body and lever throttle feel familiar if I keep using my existing 3/8 in air fittings?
Yes, the 3/8 in hose connection matches standard fittings and the lightweight aluminum housing keeps fatigue low during extended jobs.
