Ditch Witch has introduced the Rock Monster HD backreamer for horizontal directional drills (HDD) in the US, which it says offers improved performance in hard rock conditions.
The backreamers are equipped with Ditch Witch’s EdgeGuard protection designed to increase the life of the reamer, reducing costs and increasing profit. The EdgeGuard design incorporates tungsten carbide discs placed strategically on critical areas of the bit shirttail. Ditch Witch says this gives operators a significant advantage over traditional hardfacing inserts.
The backreamers are further strengthened by Ditch Witch’s High Energy Tumbling (HET) inserts, which increase bit life and production levels through increased wear resistance and fracture toughness.
“Operators continue to drill in ever-challenging terrain, making the durability of their downhole tools a critical component to a successful job,” Ditch Witch HDD tooling and drill pipe product manager Jeff Davis says.
“Incorporating new, exclusive design features, our Rock Monster HD backreamers offer superior durability and longevity, keeping underground construction crews productive and profitable even in the toughest landscapes.”
The Rock Monster includes a full-coverage cutting structure that maximizes weight on the bit, providing better performance. The backreamer has interchangeable nozzles in multiple sizes, giving operators custom fluid-flow specifications for specific drilling conditions.
The backreamers come in five different sizes and are fully compatible with Ditch Witch’s line of HDD rigs. The Rock Monster has also been designed with standard API thread connections and high fluid-flow capabilities to ensure simple integration with HDD rigs from other brands.
