What are threaded drill rods?
Threaded drill rods are generally used with hydraulic drill rigs for blasting holes and bolt holes, or as guide tubes. During the operation of hydraulic drill rigs, a drill string, composed of one drill bit, one or more drill rods, one or more couplings and one shank adapter, transmits the impact energy of the hydraulic drifter to the drill bit for direct drilling operation on the rock. Threaded drill rods are the important component in the drill string with complex force and strict requirements, so the quality and performance should be very high. According to the classification of supporting equipment and applications, the threaded drill rods can be divided into drill rods for underground tunneling, drill rods for underground long-hole drilling, drill rods for underground anchoring, drill rods for tunnel engineering, drill rods for anchoring, drill rods for surface mining, drill rods for quarrying, drill rods for surface engineering, etc.
