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 *9mm to *1mm usually. Integral drill rods are usually hexagonal with chisel tips or cross tips, the diameter are usually *9mm and *2mm. According to different application, different lengths are available from **0mm to ***0mm usually. With the best hollow drill steels and tungsten carbides, sinodrills integral drill steels will show you very good performance.
