Industrial Pistol-Grip Air Drill
The Ingersoll-Rand 1P38ST4 is a pistol-style pneumatic drill built for industrial fastening and drilling tasks. It delivers a free speed of 800 RPM and an adjustable torque range of 20 to 100 in-lb for controlled operation. The tool weighs 1.4 lb and measures 6 1/4 in overall length with a composite housing and aluminum handle. It requires a 90 psi air supply and a minimum 1/4 in hose for proper function.
Installation And Common Issues
Connection is straightforward using a standard 1/4 in air hose fitting at 90 psi regulated pressure. The trigger throttle provides variable speed control for precise starts. Ensure the air line delivers 11.0 CFM at full load and 3.00 CFM average during a 15 second run to avoid power loss. The double row ball bearings reduce vibration but require clean, lubricated air to prevent premature wear. California Proposition 65 warnings apply for cancer and reproductive harm risks.
Suitable Users And Limitations
This drill suits technicians performing repetitive drilling or fastening in metal, wood, or composite materials where pneumatic power is preferred. The 1/4 in capacity and 800 RPM speed fit general maintenance and assembly work. It is not suited for applications needing higher torque beyond 100 in-lb or larger chuck capacities. Buyers without a 90 psi compressor system delivering 11.0 CFM should look at electric alternatives. The tool lacks a reverse function limiting its use for fastener removal tasks.

Questions about this item
How do I verify the drill is delivering the rated 800 RPM free speed after setup?
Connect the tool to a 90 psi air supply using a 1/4 in hose, pull the trigger fully and listen for smooth, steady operation; the motor should reach its maximum free speed without hesitation or unusual vibration.
What accessories come in the box and what must I supply separately?
The drill itself is included; you will need to provide a 1/4 in air hose, a compatible 90 psi compressor capable of 11.0 CFM at full load, and the appropriate drill bits or driver accessories for your application.
Which capacity suits light assembly versus heavier fastening tasks?
The tool produces 20 to 100 in-lb of torque, so choose it when your work falls anywhere within that range; lighter jobs use the lower end while tougher fasteners use the upper end of the same drill.
