Thread drill rod description:
Extension rods are made by hollow drill steels; there are two shapes of extension rods, round type and hexagonal type. This hollow hole are usually named flushing hole, used for transmitting water or air during drilling. And the threads can be used for connecting couplings, shanks, couplings or button bits.
Extension drill rods are for in drifting, tunneling, long hole drilling, bench and production drilling industries. These rods are produced with round or hexagonal sections in all common thread designs, and in Male / Male (M/M) or Male/Female (M / F) connections. All our drifting and extension drill rods are heat-treated with carburization or high frequency, combinated with phosphorization
