Light drill rod（H28）

     The drill pipe belongs to the hexagonal thread drill pipe. Compared with the circular drill pipe, the hexagonal drill pipe has a larger cross-sectional area, stronger bending resistance, higher comprehensive mechanical properties, stronger drill pipe and longer life, and high efficiency. The energy is transmitted; the cross section of the drill pipe is stronger, which is most conducive to slag discharge; the small gap formed by the outer corner of the drill pipe causes eddy currents to form in the rinsing liquid hole, continuously discharging large particles, keeping the bottom of the hole clean, especially horizontal drilling.
     The drill pipe is made of high-quality steel and then CNC processed and carburized to ensure their excellent toughness and sufficient fatigue resistance to meet the most demanding working conditions. The drill pipe is matched with a low-power hydraulic rock drill for underground excavation work that does not require frequent disassembly.
