Threaded Drill Rods
Threaded drill rods are also known as hydraulic drill rods and heavy-duty drill rods, which connect with shank adaptors, hydraulic drifters and drill bits to transfer impact power and rotation torque of hydraulic drifters onto drill bits for breaking rocks. The threaded drill rods, working with hydraulic drill rigs and hydraulic jumbos, have main threads of R22，R25，R28，R32，TR35，T38，T45，T51，ST58，ST68, T60, EL60 and EL68. The threaded drill rods are divided into MF rods and extension rods, which are widely used in open-pit mining, underground mining, tunneling, anchoring, furnace tapping, tunnel construction, hydropower projects, quarrying and construction.
LHS is the first Chinese factory to manufacture drill rods and ranks the first in the industry in China regarding quality, sales volume, export volume, specification varieties and matching capacity.
