    Drill extension rod

    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.

    All extension rods are threaded and made by hollow drill steels.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 M/F rods, because one end is female, so couplings are not necessary.

    For extension drill rod, there are R32, R38, T38, T45, T51, ST58, GT60 threads, and different lengths of rods are available from 600mm to 6400mm.
