HD backreamers increase productive drilling into rock

July 12, 2017  By Administrator

Rock Monster HD backreamers from Ditch Witch are desgined to help horizontal directional drilling operators improve drilling performance in hard-rock conditions.

The new backreamers are equipped with patent-pending EdgeGuard protection to increase the life of the reamer, reduce replacement costs and keep crews profitable. This 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, the company said in a news release.

Other innovations, including High Energy Tumbling inserts, improve cutting structure life through increased fracture toughness and wear resistance, helping to extend the usable life of the backreamers.


“Operators continue to drill in ever-challenging terrain, making the durability of their downhole tools a critical component to a successful job,” said Jeff Davis, Ditch Witch product manager for HDD tooling and drill pipe, in the release.

The backreamers include a full-coverage cutting structure to maximize weight on the bit, providing better performance in rock. They are designed with interchangeable nozzles in multiple sizes so that operators can easily customize fluid-flow specifications to specific drilling conditions.

They are compatible in rock applications with current Ditch Witch HDD rigs and available in five different sizes: 10 in. x 4 cutters, 12 in. x 4 cutters, 14 in. x 4 cutters, 14 in. x 5 cutters and 16 in. x 5 cutters.
