Industrial Air Drill 3/8 Inch
The Ingersoll-Rand 7AKST6 is a pistol-grip air drill built for industrial fastening and drilling tasks. It accepts 3/8 inch shank accessories and delivers a free speed of 200 RPM with a torque range of 10 to 270 in-lb. The planetary gear train and double-row ball bearings support consistent output in production environments. Operators who need a compact, air-powered solution for repetitive hole-making will find it suited to the job.
Thermals Noise Power Draw
The drill runs on 90 psi compressed air and consumes an average of 6.25 CFM during a 15-second run, rising to 22.0 CFM at full load. Its aluminum housing with Skinsulate covering helps manage temperature during extended cycles. Variable-speed trigger control lets the user match airflow to the task, reducing unnecessary consumption. A minimum hose size of 5/16 inch is required to maintain rated performance.
Upgrade Path
This tool replaces lower-torque pneumatic drills that stall at higher resistance or lack variable-speed precision. The jump is worth it when the application demands up to 270 in-lb of torque and consistent 200 RPM free speed in a 7 5/8 inch overall length. It is not for buyers who need cordless mobility, electric power sources, or larger chuck capacities beyond 3/8 inch.

Questions about this item
How do I connect the 3/8 in air inlet and what step causes low torque?
Use a hose with at least a 5/16 in inner diameter and supply 90 psi at the tool; the common mistake is running a longer or narrower hose that drops pressure below 90 psi under load.
Which part wears first and when should I plan to service it?
The double-row ball bearings and planetary gear train carry the 270 in-lb load; expect to inspect bearings and re-grease the gear train after heavy use cycles.
What limits continuous drilling before the tool overheats or stalls?
At full load the drill draws 22.0 CFM; if the compressor cannot sustain that flow, pressure drops and torque falls below the 10 to 270 in-lb range within seconds.
