Drill rod selection should be based primarily on hole diameter and hole depth, followed by matching the rod size to the output capacity of the rock drill. For demanding drilling conditions, drill rods manufactured from high-strength alloy steel are recommended, as they provide improved service life, higher fatigue resistance, and better drilling stability.

Before operation, apply thread grease to all threaded connections to reduce wear and prevent thread seizure. After use, remove rock dust, debris, and oil residues from the rod surface to minimize corrosion and performance degradation. Use dedicated cleaning tools to remove residual cuttings inside the rod and ensure that the flushing channel remains unobstructed. After operation, apply anti-rust oil and store the drill rods in a dry, well-ventilated environment. Thread lubrication should be maintained to prevent long-term corrosion.
