ITH Drill Pipe

DPI offers a complete Range of durable ITH Drilling Tools.

Our Drill Pipe is manufactured from High Strength Moly Alloy Steel from US Mills.

We offer multiple thread profiles, S/S lengths, wall thicknesses, and wrench square configurations to match your specific machine and application.

DPI manufactures both Integral and Welded Stabilizers, from 4.50 inch to 6.50-inch Hole Size. We offer multiple designs and thread profiles. Alignment of connections and wear surfaces are checked and re-checked to insure a true smooth-running stabilization.

The Adapters and Hammer Top Subs we manufacture are extremely durable and a match for challenging ground conditions. Threads, as an option, are nitrate enameled to provide additional durability.
