Drifter rod （H35）

Light drill rod（H25）

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.

Extension rod（ST58）

The ST58 drill pipe adopts a new thread design. The thread belongs to the shoulder drive system. The base shaft shoulder transmits energy together with the sleeve. It has excellent wear characteristics and connection quality. The thread is used for multi-tube drilling with high torque. Power rock drill for surface and tunnel drilling; the larger cross-sectional area of the rod can withstand shock waves from the piston for a longer period of time. This allows the life of the drill pipe and the shank to double. The harder drill pipe provides the best drilling pattern and higher bore penetration. Compared to other drill systems, the ST58 drill system uses the same rock drill but provides a larger bore range.
