Built for high-torque drilling in manufacturing, fabrication, and heavy industrial maintenance, the Ingersoll Rand 7AMST6 Pistol Grip Air Drill combines a dependable 0.75 HP pneumatic motor with an impressive 130.1 in-lbs maximum torque to handle demanding drilling applications with confidence. Its 800 RPM free speed delivers the slower rotational speed needed for larger drill bits and tougher materials, allowing operators to maintain excellent hole accuracy while reducing bit slippage and improving overall drilling control. The trigger-start pistol grip design provides responsive throttle control and comfortable operation during extended production shifts.
As part of Ingersoll Rand's trusted 7 Series industrial drills, the 7AMST6 is engineered for continuous-duty performance in production 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 compact, lightweight construction allows users to work comfortably in manufacturing facilities, fabrication shops, and maintenance departments without sacrificing drilling power.

FAQs:
- Q: What types of applications benefit from the 130.1 in-lbs torque output?
A: The 7AMST6 is well suited for larger drill bits, thicker materials, and applications that require greater drilling force while maintaining excellent control at lower operating speeds. - Q: Is the 7AMST6 reversible?
A: No. This model is a non-reversible drill intended for dedicated forward drilling applications. - Q: What chuck capacity does this drill feature?
A: The 7AMST6 is equipped with a 3/8-inch (10 mm) chuck for compatibility with a broad range of industrial drill bits. - Q: What compressed air supply is recommended?
A: The drill consumes approximately 25 CFM and features a 1/4-inch NPT air inlet. A minimum 5/16-inch air hose is recommended to maintain consistent airflow and dependable drilling performance.
