The characteristic of this kind of drill rod is that the shank adapter, rod, coupling sleeve and bit are connected into a rock drill string group through the threads on the rod body. The basic requirements of the drill string for the connecting thread are: tight connection, good energy transmission effect, strong wear resistance and convenient disassembly. At present, there are two commonly used thread forms: rope thread (R32,R35,R38...) or trapezoidal thread (T38,T45,T51...). Product Advantages  Production flow : 1. Raw material preparing 2. Upsetting extrusion 3.Friction welding 4. Roughing 5. Threading 6. Heat treatment 7.Straightening 8. Shot peening 9. Quality Inspection 10.
