    T38 Threaded Drill Rod

     

     

    T38 Thread Drill Rod

     

    T38 drill rod, other names are extension drill steel, extension drill rod, and Extension steel, M/F rod (Speed rod).

     

    Two Type: Hexagonal and round cross-sections.

     

    Hexagonal rods are more rigid, heavier and transfer energy more efficiently while increasing flushing.

     

    Round rods are generally lighter than hexagonal rods and are normally used in extension drilling applications.

     

    With the longer steel tending to be larger in diameter, conventional extension steel is characterized by the duplicate thread on each end of the steel.

     

    Extension rods are made by hollow drill steels, different lengths are available from 600mm to 6400mm.

     

    This hollow hole is usually named flushing hole, used for transmitting water or air during drilling.

     

    And the threads can be used for connecting couplings, shanks adapters or button bits.

    Drill rod using T38 threaded 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

     

    Material: Tungsten carbide and high strength alloy steel

     

    Processing: CNC milling and proprietary heat treatment process
