Friction type drill Kelly bar is a kind of drill pipe type with international advanced six-ribs distribution technology composition.The Kelly bar can generate pressure force when the Kelly bar rotarying can produce peripheral force and the rotary passing down the pressure force can produce the friction force. It is simple operation, drilling depth . it is suitable for soft soil layer and mud sand layer.The complete set of Kelly bar is with light weight, high strength, high linearity of the single drill pipe.; The inner and outer layer collocate reasonably , with good wear resistance plate.. it is greatly to meet the special requirement of the drill rig machines.
