Product description:
DTH drill pipes play a significant role in all DTH drilling, regardless type of rock, hole depth or drill rig.
The key features of a high quality DTH tube are durability, accuracy and manageability.
According to different application, different diameters of drill tubes are needed, basically, smaller DTH hammers need smaller DTH drill tubes, vice versa.
