Ditch Witch AT Drill Rods for JT40 AT AT40 – 3.25 Thread

All Terrain Drill Rods for Ditch Witch AT40 We offer new All Terrain HDD drill rods compatible with Ditch Witch AT40 drilling rigs, equipped with the 3.25 thread system. All Terrain drill rods are designed for demanding HDD rock drilling applications, where standard drill rods are not sufficient. The dual rod system allows independent power transmission: the inner drive shaft transfers torque directly to the drilling tool, while the outer rod supports steering and directional control. These rods are suitable for HDD works in rock, compact ground and difficult geological conditions. They are used in professional All Terrain / Rock Drilling systems for pilot drilling and demanding trenchless construction projects. The rods are manufactured from certified heat-treated alloy steel, grade S135. This steel grade provides high fatigue resistance, tensile strength and torsion resistance, which are essential when working under high torque and demanding drilling cycles. The drill rods are manufactured using hot-forging technology. This construction provides high durability and reduces the risk of failure in the tool joint area.
