Threaded drill rods


Threaded drill rods are also known as hydraulic drill rods and heavy-duty drill rods, which connect with shank adapters, hydraulic rock drills and drill bits to transfer impact power and rotation torque of hydraulic rock drills onto drill bits for breaking rocks. The threaded drill rods, working with hydraulic drill rigs and hydraulic rock drills, 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 surface mining, underground mining, tunneling, bolting, furnace tapping, tunnel construction, hydropower projects, quarrying and construction.
