  • Delivers consistent power with 0.30 HP motor
  • Reaches 700 RPM free speed for efficient drilling
  • Consumes 3.00 CFM average during 15-second runs
  • Requires 90 psi operating pressure for reliable performance
  • Aluminum housing and handle resist wear in industrial use

Compact Air Drill for Precision Work

The SPEEDAIRE 45YY28 is a pneumatic drill built for industrial duty cycles. It delivers 0.30 HP and a free speed of 700 RPM through a 1/4 in threaded chuck. The right-angle body style and lever throttle suit tight workspaces and controlled operation.

Air Supply Limits at 90 psi

Operation requires 90 psi inlet pressure through a 1/4 in NPT fitting with a minimum 3/8 in hose. Average consumption is 3.00 CFM during a 15 second run, rising to 12.0 CFM at full load. Torque ranges from 0.60 to 0.70 ft-lb within these air delivery constraints.

Upgrade from Lower-Capacity Drills

This model replaces drills that lack variable speed control or sufficient torque for tougher materials. The jump is worth it when tasks demand reversible drilling, higher torque output, or the durability of an aluminum housing for sustained industrial use.

Questions about this item

Should I pick the 0.30 HP or 0.60–0.70 ft-lb torque version of this drill?

This model is a single configuration rated at 0.30 HP and 0.60–0.70 ft-lb torque; there are no separate versions to choose between.

What does the 700 RPM free speed mean when I am actually drilling?

Free speed is the no-load maximum; under load the drill runs slower, and the 0.60–0.70 ft-lb torque range determines how fast it cuts through material.

How does the 1/4 in NPT air inlet limit airflow in practice?

The 1/4 in NPT inlet requires a minimum 3/8 in hose and 90 psi supply; at full load the tool draws 12.0 CFM, so the compressor and hose must sustain that flow.
