Rock Monster HD backreamers are made for HDD operators drilling in hard rock conditions.
The backreamers are equipped with patent-pending EdgeGuard protection to increase the life of the reamer, Ditch Witch says. The design incorporates strategic placement of tungsten carbide discs on critical areas of the bit shirttail, giving operators an advantage over hardfacing and tungsten carbide inserts. Other innovations, including patent-pending High Energy Tumbling inserts, are designed to improve cutting structure life. Interchangeable nozzles in multiple sizes allow operators to customize fluid-flow specifications to specific drilling conditions.
