    Describtion

     

    Produce Hexagonal and round cross sections.

    Hexagonal cross sections 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 a duplicate thread on each end of the steel.,

     

    For Extension Rod and M/F steel process, the below two different types of heat treatment are used to strengthen high speed and powerful percussive drill string components to maximize their performance and reliability. Longer steel larger in diameter, conventional extension steel, Hexagonal and round cross sections are available.
    1.Carburization is a process used to harden the entire rod surface both internally and externally to strengthen and extend the life of the rod.
    2. High Frequency Induction is a process where only the thread ends of the rod are hardened to lengthen thread life.

     

    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

    Male/Female (M/F) rod, Speed rod
    M/F drill steel is an alternative to couplings sleeves to include the female part of the threaded connection as an integral part of the drill steel. M/F drill steel provides more rigid connections and is easier to uncouple and handle. The service life also tends to be better than with separate couplings.

    Advantages of drilling with M/F rods:

    A: Easy handling

    B: quicker uncoupling

    C: tighter connections

    D: the potential to drill straighter holes

    E: longer service life.
