A drill rod is a hollow metal pipe with an external thread at one end and an internal thread at the other. When the drill head moves along a given trajectory, the rods are alternately screwed one after the other, so the "cable" (column of rods) is extended and through it the drilling fluid enters, as well as rotation is transmitted.
Drill rods are made of particularly strong steel grades (S135), and according to the manufacturing method are divided into two types:
- solid forged
- made by welding (usually friction welding)
Solid forged rods are quite strong, thanks to the integrity of the part, but they have little flexibility, and the threaded ends wear out quickly. The second method involves increased strength of the ends, so they wear out to a lesser extent, but the welding seam can be a weak point.
