External Flat Drill Rod

Drill rods have a diameter of 19-168mm and a length of 0.5-9m. The material includes alloy steel such as 42CrMo, with a tensile strength of 800-1200MPa. The surface is treated for wear resistance, and the joints are mostly connected by tapered or straight threads. It is mainly used in geological exploration, mining, water well construction and other scenarios to transmit torque and axial pressure, and realize the rotary drilling and core extraction of the drill bit.
