American Machine & Gundrilling Equipment


Gundrilling operations use individualized equipment to drill and bore holes in various materials for several industries. Our technology is upgraded, re-upgraded, tooled, and re-tooled to ensure the highest quality products are fabricated to stringent requirements.


Specialized for Challenging Diameters & Depths

The technology American Machine & Gundrilling (AMG) uses is highly specialized and modified to our processes. To eliminate unnecessary downtime, we have machine duplicates, and we focus on keeping our equipment maintained and up-to-date with the latest technology. At AMG, we can manufacture components with smaller, deeper holes than any other traditional drilling operation.

Our various machines quickly achieve complex and challenging depths and diameters, offering flexible turnarounds as fast as a day, with capabilities for angled, concentric, intersecting holes and additional hole types. Providing high accuracy and speed, fabricating the exact components you need is fast and easy with gundrilling operations. Additionally, AMG engineering experts conduct extensive inspections to ensure quality.
