Steel Drill Rod is a core tool in rock drilling operations, used to connect the rock drill and the drill bit, transmitting impact energy, torque, and flushing media (such as high-pressure air or water) to achieve tasks such as rock drilling and blast hole formation. Its design integrates high strength, wear resistance, and impact resistance, and it is widely applied in heavy industries such as mining, tunnels, and infrastructure construction.
