Built for high-torque drilling in manufacturing, heavy fabrication, and industrial maintenance, the Ingersoll Rand 7ANST8 Pistol Grip Air Drill combines a reliable 0.75 HP pneumatic motor with an impressive 185 in-lbs maximum torque to tackle demanding drilling applications. Its 500 RPM free speed provides the controlled rotation required for larger drill bits and thicker materials, helping improve hole accuracy while reducing bit chatter during low-speed drilling. The trigger-start pistol grip configuration offers smooth throttle control and balanced handling, making it well suited for repetitive industrial drilling tasks.
As part of Ingersoll Rand's proven 7 Series industrial drills, the 7ANST8 is designed for dependable performance in continuous-duty environments. The non-reversible configuration is optimized for dedicated forward drilling applications, while the cantilever-mounted planetary gear system efficiently transfers motor power and simplifies maintenance. Its lightweight yet durable construction makes it a practical choice for production workstations, fabrication facilities, and maintenance departments where reliable low-speed, high-torque drilling is essential.
