Product Description

The Critical Link for Accurate and Efficient Underground Boring

The PortaMole Drill Stem is an essential component of the PortaMole underground boring system, providing the strength, control, and directional accuracy needed for trenchless utility installations. Designed to connect the boring head to the power unit, the drill stem transfers rotational force and water flow while advancing the bore beneath driveways, sidewalks, roads, parking lots, and landscaped areas.

Built for durability and reliability, PortaMole drill stems are engineered to withstand the demanding conditions often encountered during trenchless boring projects. Whether installing irrigation sleeves, electrical conduit, water services, telecommunications lines, or fiber optic infrastructure, the drill stem plays a vital role in maintaining a straight, accurate bore path while allowing operators to extend the overall boring distance as needed.

For contractors working in Hawaii’s diverse soil conditions—including clay, compacted soils, coral, and rocky terrain—the PortaMole drill stem provides the strength necessary to support efficient utility installation while minimizing excavation and surface restoration costs.
