Integral drill rods(integral rods or integral drill steel) are used for small hole drilling, usually they are used for some small projects or remote place. Equipped with small power rock drills, like air leg rock drills, hand held rock drills, etc. integral drill rods can be used for drilling bore hole diameter from 29mm to 41mm usually. Integral drill rods are usually hexagonal, the diameter are usually 19mm and 22mm. According to different application, different length are available from 600

 Make drill rods and drill bits together, then it is integral drill rod. Compared with integral drill rods, taper drill rods (taper drill steels) work with taper drill bits, like integral drill rods, taper drill rods have different length for different application. Because taper drill rods need taper drill bits to work, therefore there are different taper degree, like 7, 11, 12,etc in the world. This depends on customers request. The basic theory is that taper drill rods

Extension rods are one major spare part in terms of drill stems, there are two shapes of extension rods, one is round type, another one is hexagonal type. But all extension rods are threaded and made by hollow drill steels, this means usually extension rods are hollow.This hollow hole are usually named flushing hole, used for transmitting water or air during drilling. Two ends threads can be used for connecting couplings, shanks, couplings or bits. Typically two ends of ex

Tapered chisel bit is one traditional drill bits with long history in the world, due to its simple production process, they are used widely in the world from the last century. Chisel bits means carbides are chisel type.Like taper drill rods, taper chisel bits have different taper degree according to customers request. And the diameters varies from 20mm to 60mm.According to the total height of taper chisel bits, there are short skirt taper chisel bits and long skirt chisel

 Tapered button bits are one advanced type of taper drill bits if compared with taper chisel bits and taper cross bits. With carbide buttons hot pressed on bits bodies, taper button bits have a very good drilling performance and life time. So currently such drill bits are the most popular in the world. Basically different diameters and taper degrees are available, just same as all other taper drill bits. There are short skirt button bits and long skirt button bits accordi

Same as taper button bits, threaded button bits are most popular drill bits in the world now. Like threaded cross bits, button bits shapes can be cylinder or retrac. And the thread sizes can be R22,R25,R28,R32, R38,T38,T45 or T51,SR28,SR32,SR35,ST58,ST68,etc The diameters can be 38mm to 152mm, etc. Our all threaded button bits are hot pressed. Hot press is one most advanced production technologies in the world for button bits. And drill bits bodies are forged from very goo

Because of different applications, we need different lengths of drill stems, so couplings sleeves are used for connecting extension rods. There are semi-bridge couplings and full bridge couplings, the only difference between them is that semi-bridge couplings have a middle stop at the middle of couplings. Usually couplings two ends are the same couplings, like R25, R32,R38,T45, T51, etc .While sometime people need crossover couplings to work, for example, one end is R32 an

 In the drilling industry, there are many ways regarding the connections between different spare parts, for example, for taper drill rods and taper drill bits, taper degree is one way. While there is another way, that is by threads. This means different spare parts can be connected by threads. So we say shank adapters, couplings, extension rods, threaded cross bits and threaded button bits belong to threaded drilling products. Shank adapter is used for transmitting power
