Rock Boring Units
The Rock Boring Unit (RBU) makes it possible to use any manufacturer’s auger boring equipment to install a range of common diameter steel casing pipe in high compressive geology. The RBU features 6.5‐in. disc cutters, muck scrapers, a high capacity main bearing, and water‐jetting to advance pipe through rigorous ground conditions. The RBU performs well in rock and varying challenging ground conditions.
Water‐jetting actively cools the cutter head tooling and bearing assembly resulting in extended performance, reduced wear, and lower operating costs.
FEATURES:
- Use any auger boring machine to install 24–48‑in. steel casing.
- Robust design with high‑capacity thrust load disc cutters to aggressively fracture rock into cuttings.
- Cutter head rock scrapers help transfer cuttings from the face to the inlet cavity and into the lead auger for removal.
- Fluid connection ports cool the bearing assembly for longer life and clean disc cutters in clay/silt conditions.
- RBUs are inventoried and available globally, with rental options in North America.

Testimonials
Akkerman has proven to be the “go-to” manufacturer of American Made TBM’s, GBM’s, and pipejacking systems. This is not just based on the 13+ years I’ve been doing business with them, but the nearly 40-years of successful partnering between Pacific Boring and Akkerman, a relationship I look forward to continuing.
