Feature of the extension rod MF rod:Â Â
           Drill rod using thread system. Drilling precision can be further improved by using this as the first rod in a normal drill string. Furthermore, since this is a speed rod design it will produce straighter holes and at least 10% higher penetration rate in good rock conditions compared to rod and coupling sleeve combination system.  Widely used in drifting, tunneling, benching, and long hole drilling High strength chromium-molybdenum steel with high fatigue strength and excellent wear resistance Type: Hex. Drifter Rod, Extension Rod, Speed Rod, MF-Rod Color: Based on Customer requirements Material: Tungsten carbide and high stre ngth alloy steel Processing: CNC milling and proprietary heat treatment process
Advantage of the extension rods MF rods:
          Extension rods are one major spare part in terms of drill application area, there are two shapes of extension rods, one is round type, another one is hexagonal type. But all extension rods are threaded and made by hollow drill steels, this means usually extension rods are hollow. This hollow hole are usually named flushing hole, used for transmitting water or air during drilling. Two ends threads can be used for connecting couplings, shanks, couplings or bits. Typically two ends of extension rods are male, while sometime one end is male and another one is female, then we call it M/F rod. We need couplings to connect extension rods, while for MF rods, male and femal rods, because one end is female, so couplings are not necessary. Â
