D36X50DR Series ll features a rod-in-rod design that provides 1,500 ft.-lb. of rotational torque. As the inner rod powers the downhole tri-cone, the outer rod provides steering and backreaming rotations. Its dual-threaded rod design allows a drilling fluid course between the inner and outer rod, and through the inner rod for cuttings removal. The DR is a drill rod within a drill rod that opens up the water force to get all the water into production. It can be transformed into a standard drill in less than 30 minutes. The D36X50DR has on onboard rod carrying capacity of 500 feet and has the same 38,000 pounds of thrust/pullback and 5,000 ft.-lb. of rotation torques as the conventional D Series ll Navigator HDD.
The D10x15 S3 Navigator horizontal directional drill replaces the D9x13 S3 drill.
Three backreamers are designed to aid underground work in specialized soil conditions and installations.
The D60x90 S3 horizontal directional drill has 60,000 pounds of thrust/pullback and 9,000 lb.-ft. of rotational torque.
The D24x40 Navigator horizontal directional drill has 28,000 pounds of thrust and pullback and 4,200 lb.-ft. of rotational torque.
