The Swab backreamer is specifically designed for rocky and hard soils, and enables direct pullback for Ditch Witch All Terrain HDD rigs.
Ditch Witch has released a new line of backreamers to help underground construction operators improve productivity in specialized soil conditions and installations.
The new models include the Sandhog HD (heavy duty), Swab and EZ backreamers. All models are designed with customer input in mind, job site efficiency and long life, according to the manufacturer.
“When it comes to productivity in complex soil conditions, backreamers are key to a successful horizontal directional drilling [HDD] job,” said Jeff Davis, Ditch Witch product manager of HDD tooling and drill pipe. “We know the ability to pre-clean a path or quickly connect to a rig is often required. That's why the latest models build on the Ditch Witch reputation for rugged, long-lasting design and are tailored to specialized soil conditions, improving an operator's ability to efficiently install product.”
Sandhog HD Backreamer
Designed for sandy and soft soils, the triple-action Sandhog HD backreamer combines aggressive cutting, mixing and packing for more efficient pullback on the job. Bore paths in unstable soil conditions can often collapse or fill with material in the ground. This backreamer uses a barrel-shaped body to better sculpt a true-to-size bore path.
Carbide cutting teeth and spiral plates further improve pullback efficiency and lower torque while maximizing the capacity for fluid flow. The crushed carbide provides longer life to the reamer and replaceable, hardened steel nozzles increase fluid flow flexibility.
The Sandhog HD backreamer is available in 2 3/4-in. (7 cm) shaft size with 2.0 IF threads and 3 1/4-in. (8.2 cm) shaft with 2 3/8 API threads, ranging in diameter from 8 to 18 in. (20 to 45.7 cm). Compatible Ditch Witch HDD rigs include the JT9, JT20, JT25 and JT30.
The Swab backreamer is specifically designed for rocky and hard soils, and enables direct pullback for Ditch Witch All Terrain HDD rigs. Material left in a bore can damage product when deployed in restricted spaces. This model effectively pre-cleans the bore path by efficiently utilizing fluid flow and the carbide hard surface. Material removal also helps install product without enlarging the path beyond the pilot size. By eliminating the need for an expanded path, the backreamer saves on fluids and time.
The Swab backreamer is available in a 3 1/4-in. shaft with a 2.77 male thread size, and for a diameter of 5 1/2-in. (14 cm). The model is compatible with the JT30 All Terrain HDD.
For small-diameter installation jobs, the EZ backreamer combines ease of use with effectiveness. It was designed for direct connection to the EZ connect assembly, allowing operators to quickly change out tooling in a fast, safe and efficient manner. The model is equipped for use in soft to medium-hard soil conditions.
The EZ backreamer is available in a 3 1/4-in. shaft size with an EZ2 and EZ3 connection, ranging in diameter from 6 to 8 in. (15.2 to 20 cm). Compatible Ditch Witch HDD rigs include the JT20, JT25 and JT30.
