Industrial Pistol Air Drill
The Ingersoll/Rand 7AQST8 is a new pneumatic pistol drill built for industrial fastening tasks. It delivers free speed of 600 RPM and adjustable torque from 10 to 270 in-lb. The aluminum handle and Skinsulate housing keep the tool weight at 3.2 lb. Double-row ball bearings and a planetary gear train support sustained operation.
Suited For Repetitive Assembly Work
This drill suits technicians who need variable-speed control via a trigger throttle for repetitive drilling or driving. It requires a 90 psi supply, 22.0 CFM at full load and a minimum 5/16 in hose. Buyers without a compressor that can sustain that flow, or who need a cordless solution, should look elsewhere.
Straightforward Pneumatic Hook-Up
Installation consists of connecting a properly sized air line to the 5/16 in inlet at 90 psi. The 8 3/4 in overall length fits most work positions. The most common issue is insufficient compressor capacity causing pressure drop below the required level, which reduces torque and speed. Regular lubrication of the air motor prevents premature bearing wear.

Questions about this item
What size air hose is required for the 7AQST8 to deliver its rated 6.25 CFM average?
The minimum hose size is 5/16 in, which supports the 6.25 CFM average at 15-second run time and 22.0 CFM at full load.
Will the 7AQST8's 1/2 in chuck and 10-270 in-lb torque range work with my existing 3/8 in drill bits?
Yes, the 1/2 in chuck accepts bits with shanks up to 1/2 in, so your 3/8 in bits will fit and operate within the 10-270 in-lb torque range.
How can I confirm the 7AQST8 is producing its specified 600 RPM free speed after installation?
Run the drill at full throttle with no load; the motor should reach 600 RPM free speed when supplied with 90 psi air pressure.
