A rock drill extension rod, as the name implies, is an additional shaft attached to a primary drill rod, designed to extend the drilling depth and range. It is primarily used with percussion or rotary rock drills, which are employed for drilling through hard and abrasive rock formations. These rods are made from high-strength materials like alloy steel, ensuring durability and resistance against the harsh conditions encountered in drilling applications.
