Thread post tooth bit


Threaded drill bits are connected with drill rods by threads to transfer impact power and rotation torque for breaking rocks. With main threads of R22，R25，R28，R32，TR35，T38，T45，T51，ST58，ST68，EL60，EL68 and T60, the threaded drill bits are mainly used with hydraulic drill rigs and hydraulic rock drills in surface mining, underground mining, tunneling, bolting, furnace tapping, tunnel construction, hydropower projects, quarrying and construction.

In 1991, LHS pioneered the introduction of European thermal-pressing process and technology to enable the production of threaded button bits for hydraulic drilling machines, which comprehensively propelled and elevated the overall quality standard of Chinese button bits. Today, LHS has held the top spot in quality, specifications, production capacity, sales volume and export volume of button bits s in China.
