Hex22mm 108mm Shank Integral Drill Steel Rod For Underground Coal Mining

Hex22mm 108mm shank Integral drill steel rod for underground coal mining

 
Integral drill rod

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.

Integral drill rods are ideal in small hole drilling, all integral drill rods consist of hex. rods with integrated cemented carbide chisel-shaped bit heads. With the same steels as and the best carbides made in China, we are supplying different lengths of integral drill rods with different head diameters.

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.

It can reduces the expense of impact energy, improves the drilling speed and efficiency, also it can be used for drilling bore hole diameter from 30mm to 41mm usually. Each rods use premium quality alloy steel and excellent quality tungsten carbide to assure.
