       Ordinary rough drill rod is a commonly used type of drill rod in drilling engineering. It is usually made of high-quality alloy steel material and undergoes special heat treatment to have high strength and toughness. During the drilling process, the drill rod needs to frequently contact and rub with various media such as rock and soil. The surface of ordinary rough drill rod has undergone wear-resistant treatment to have good wear resistance, which can effectively reduce the wear of the drill rod, extend the service life of the drill rod, and reduce drilling costs. Compared with some special materials or high-performance drill rods, the manufacturing cost of ordinary rough drill rod is relatively low. It has been widely used in many conventional drilling projects due to its high cost-effectiveness while meeting the requirements of general drilling engineering.
