The PortaMole® 3-Inch Rock Bit is designed for challenging underground boring applications where standard soil heads cannot effectively penetrate compacted ground, coral, fractured rock, or rocky soil conditions. Built from hardened steel, this heavy-duty boring head improves performance and durability when installing utilities beneath driveways, sidewalks, roads, and landscaped areas.
For Hawaii contractors, the 3″ rock bit is an excellent solution when working in coral, volcanic soils, cinders, and other difficult ground conditions commonly found throughout the islands.
Available from Service Rentals & Supplies locations on Maui, Oahu, Kauai, and the Big Island.
