Ditch Witch Drill Rods for JT520 – DW 1.1 Thread

Drill Rods for Ditch Witch JT520 We offer new HDD drill rods compatible with Ditch Witch JT520 compact drilling rigs, equipped with the DW 1.1 thread system. These drill rods are designed for professional Horizontal Directional Drilling works, where precise torque transfer, pulling force resistance and stable drilling fluid flow are essential. They are suitable for compact HDD machines used in fibre optic installation, water connections, power cable works and other small to medium trenchless projects. The rods are manufactured from certified heat-treated alloy steel, grade S135. This material provides high fatigue resistance and durability, which are important when working in demanding ground conditions and during repeated bending cycles. The drill rods are produced using friction welding technology. This method provides a strong and reliable connection between the pipe body and tool joints, supporting stable performance during HDD drilling operations. Precision-machined DW 1.1 threaded connections ensure reliable make-up, tight connection and proper drilling fluid transmission during operation. The rods are compatible with the Ditch Witch JT520 drilling system.
