How to Select Drilling Rods?
Drill rods that are used in applications such as DTH/ DTHR/ DR
basically comprise of a steel pipe with a pin at one end and a box
on the other. The job of the drill rod is to transmit rotational
torque and thrust from the drill rig rotary head to down hole
drilling tools.
