What Are Junk Mills?

Junk mills are heavy-duty milling tools used in the oil and gas industry to remove junk, debris, and unwanted obstructions from the wellbore. Designed with high-strength steel and tungsten carbide inserts, junk mills are deployed on the drill string to grind up stuck tools, fish, bridge plugs, cement, and other metallic or non-metallic objects.

At ProGrynd, we specialize in manufacturing premium-quality junk mills tailored for various downhole conditions. Our tools are trusted for durability, aggressive cutting action, and unmatched reliability in even the most challenging environments.
