Built for demanding drilling applications in manufacturing, fabrication, and industrial maintenance, the Ingersoll Rand 7ALST6 Pistol Grip Air Drill combines a dependable 0.75 HP pneumatic motor with 78 in-lbs maximum torque to deliver the power required for larger drill bits and heavier-duty drilling tasks. Its 1,200 RPM free speed provides excellent control when working with thicker materials, helping reduce bit walking while improving drilling accuracy and finish quality. The pistol grip configuration with trigger-start throttle offers responsive control and comfortable handling throughout repetitive production operations.
As part of Ingersoll Rand's proven 7 Series industrial drills, the 7ALST6 is designed to provide reliable performance in continuous-duty environments. The non-reversible configuration is optimized for dedicated forward drilling, while the cantilever-mounted planetary gear system efficiently transfers motor power and simplifies routine maintenance. Its lightweight construction and compact profile make it well suited for production lines, maintenance shops, and fabrication facilities requiring dependable pneumatic drilling performance.
