Built for high-speed precision drilling in manufacturing, maintenance, and metal fabrication environments, the Ingersoll Rand 7ADST4 Pistol Grip Air Drill delivers 0.75 HP of pneumatic power and 10 in-lbs maximum torque for controlled drilling in light-duty materials and repetitive production work. Its 20,000 RPM free speed allows fast hole creation with clean results, making it well suited for assembly operations where speed and accuracy are equally important. The pistol grip configuration provides familiar handling and responsive trigger control, helping operators maintain precision throughout extended drilling tasks.
Designed as part of Ingersoll Rand's industrial 7 Series, the 7ADST4 combines lightweight construction with a durable planetary gear drive to deliver dependable performance in continuous-use environments. The non-reversible trigger-start design simplifies operation for dedicated drilling applications, while the compact profile allows improved maneuverability around fixtures, machinery, and production workstations.
