Vermeer Drill Rods for D33x44 / D36x50 – FS1 #650 Thread

Drill Rods for Vermeer D33x44 / D36x50 We offer new HDD drill rods compatible with Vermeer D33x44 and D36x50 drilling rigs, equipped with the Firestick 1 #650 FS1 thread system. These drill rods are designed for professional Horizontal Directional Drilling works where reliable torque transfer, pulling force resistance and stable drilling fluid flow are essential. They are suitable for long-distance drilling projects, utility installation, water and sewage networks, gas pipelines, power cable projects, fibre optic works and other trenchless construction applications. 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 important when working with high pulling forces and in demanding ground conditions. The drill rods are manufactured using hot-forging technology. This construction provides high durability, reduces the risk of failure in the tool joint area and supports stable drilling fluid transmission during operation. Precision-machined Firestick 1 #650 FS1 threaded connections ensure reliable make-up, tight connection and proper drilling fluid flow. The rods are compatible with Vermeer D33x44 and D36x50 drilling systems using 4.5 m drill rods.
