NQ drill rod - Made-to-order

Description of Drill Rods:

In order to meet different drilling applications in mining, quarrying as well as energy exploration, we usually need different lengths of drill stems, so coupling sleeves are needed to connect extension rods. There are two types of couplings: semi-bridge couplings and full bridge couplings. The only difference between them is that the former have a middle stop at the middle of couplings. Generally, two ends of couplings are the same, like R25, R32, R38, T45, T51, etc. But sometimes, crossover couplings are needed, for example, one end is R32 and the other end is R38, but basically all couplings are female threads.

We can manufacture all kinds of bits and shells according to customer's special requirement.

Description of Integral drill rods:

Integral drill rods(integral rods or integral drill steels) are used for small hole drilling. Equipped with small power rock drills, like air leg rock drills, hand held rock drills, etc. integral drill steels can be used for drilling bore hole diameter from 29mm to 41mm usually. Integral drill rods are usually hexagonal with chisel tips or cross tips, the diameter are usually 19mm and 22mm. According to different application, different lengths are available from 600mm to 9600mm usually. With the best hollow drill steels and tungsten carbides, sinodrills integral drill steels will show you very good performance.
