Product Description

In DTH drilling, drill rods and bits are the most important parts of the drilling process. When working, the drill rods transmit the necessary feed force and rotation to hammer and bit plus compressed air or fluids for the hammer and flushing of cuttings, the hammer is located between the drill rod and bit. As the hole gets deeper, the length of drill rod must be increased, so one and one drill rods are needed to increase the total length of the drill rods.
