Drill rod threads are divided into several main types, including square threads, taper pipe threads, spiral threads, and straight threads. These threads have their own unique characteristics and are suitable for different drilling conditions and requirements. The selection of thread type depends on factors such as the diameter of the drill rod, the material to be drilled, the drilling depth, and the torque required. It is recommended to consult professionals or manufacturers for specific selection advice to ensure that the drill rod threads meet the needs of the project.
