Pistol Air Drill for General Use
The Ingersoll/Rand 728NA3 is a 1/2 inch pistol-style air drill built for general drilling tasks. It delivers a free speed of 950 RPM and adjustable torque between 30 and 120 in-lb. Variable speed control via the trigger allows precise operation. The composite housing and aluminium handle keep weight to 3.1 lb.
Compressor and Hose Requirements
Verify your air supply can maintain 90 psi at the tool inlet during use. The drill consumes an average of 4.75 CFM over a 15 second run time. A minimum hose size of 3/8 inch is required to avoid pressure drop. Ensure fittings and regulator capacity match these demands before ordering.
Upgrade from Smaller Chuck Drills
This model replaces 3/8 inch chuck drills when larger bit capacity is needed. The jump is worth it for jobs requiring 1/2 inch bits or higher torque up to 120 in-lb. It is not suited for buyers who need angle-drill access in confined spaces or significantly higher free speeds.

Questions about this item
Does the 728NA3 pistol air drill come with drill bits and an air hose, or must they be purchased separately?
The drill is supplied as the tool only; drill bits and a 3/8 in minimum hose must be bought separately.
Which chuck capacity suits the 1/2 in 728NA3 for general workshop use?
The 1/2 in chuck capacity matches the model specification and handles the 30 to 120 in-lb torque range for general drilling tasks.
What does the 950 RPM free-speed rating mean when the drill is running under load?
Free speed is the no-load maximum; under load the speed drops, while torque rises up to 120 in-lb at 90 psi.
