SPEEDAIRE 21AA75 Air-Powered Drill
The SPEEDAIRE 21AA75 is a pneumatic drill built for technicians who need a compact, reversible tool for drilling and fastening tasks. It runs on compressed air at 90 psi and delivers 800 RPM free speed with 9.10 ft-lb of torque. The pistol-grip design suits automotive, maintenance and assembly work where electric power is unavailable or impractical.
Aluminium housing with keyless 1/4 in NPT chuck
The housing and handle are aluminium, keeping weight to 3.1 lb while resisting shop wear. A keyless 1/4 in NPT chuck allows rapid bit changes without a separate key. The trigger throttle gives direct speed control, and the 2-step planetary gear train provides smooth power delivery. Ball bearings support the spindle for longer service life.
Check air supply and hose before ordering
The tool requires 90 psi operating pressure and consumes 4.00 CFM average over a 15-second run, rising to 16.0 CFM at full load. A minimum 3/8 in hose is specified to maintain flow. Verify your compressor can sustain this demand and that your fittings match the 1/4 in NPT inlet. Variable speed is not available on this model.
