S series Drill Rod

      The S series drill rod is a widely used type of drill rod, developed specifically for underground rock excavation and open-pit drilling projects that require high-quality anchor support and excavation equipment. It is suitable for the new generation of powerful hydraulic rock drills. It uses more materials to resist thread fracture stress, greatly improves fatigue strength, reduces internal recoil tension waves, can reduce drilling tool group stress, reduce wear of rock drills and drilling rig components, and extend service life.
