A rock drilling rod, typically made from high-strength alloy steel, is a cylindrical shaft that connects the drill rig to the drill bit. Its primary function is to transmit the mechanical energy from the drilling machine to the bit, facilitating the drilling process. The rods' durability and resistance to deformation under immense pressure are crucial attributes, as they are subjected to rigorous forces during drilling operations.
