TAISHAN Drifter rods are made by hollow drill steels; there are two shapes of Drifter drill 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 bits.Usually for Drifter rods, there are R22, R25, R28, R32, R38, T38, T45 ,T51,ST58, T60 threads, and different lengths of rods are available from 600mm to 6400mm usually.
1.Our thread drill rods are made of high-intensity alloy steel imported from shanghai baogang.
2.All the trails and threads are formed by high precision CNC machines.
3.For MF rod,we use mature friction welding technology to increase the using life of thread.
4.Holistic carburization increases the carbon content in the outer layer of drill rod, and hardened outer steel body.
5.The solid thread can fit perfectly with the inner wall of the drill bits,and complete various roadway tunneling, underground mining and open pit drilling task in complex rock and terrain rough drilling with high precision and high efficiency .
