Geological Drill Rods Wireline Drill Rods DCDMA Standard Superior
Strength
1. We manufacture drill rods are crafted from quality heat treated
materials ensuring superior wear resistance, strength, and
toughness in the most demanding applications.
2. his wire line rod is the equipment that connects the drilling
tools and drilling bits, and it is mainly used to transmit power.
It mainly consists of a tubing body and two thread ends.
3. The function of the wire line drill rod :
(1) To transfer torque and rotation from the core drill rig to the
drill bit;
(2) To transfer the lifting and pull forces;
(3) To serve a distribution line for the flushing water;
(4) To serve as a distribution line for the inner tube assembly.
