    We can also call such thread extension drill rod as threaded drill

    rod or threaded pipe, they own one end thread or both ends thread, with

    hollow round body or hollow hexagonal body.

    It is the main part of the

    threaded connection drilling tools or drilling equipments.

    Threaded

    drill rod is connected with top hammer rock drill rigs via shank

    adaptors & couplings, another end, they are connected with drill bits

    via thread also.

    Threaded rod could be connected with other drill rods

    to constitute a complete set of threaded connection whole drilling tools

    for drilling.

    Threaded drill rods could be connected with one piece of

    shank adapters and drill bits, or connected with lots of adaptors and

    bits.

    And ther can also be used in shallow holes and small diameter rock

    hole drilling, the applicable scope is wide, drilling speed, impact

    energy transmission loss is small, high drilling efficiency, easily to

    realize the drilling mechanization and improve the superiority of

    drilling conditions.

    Therefore, thread extension drill rods share a very

    very big proportion in the whole drilling fields.

    Thread extension steel bars for rock drilling must own high fatigue strength, elasticity, rigidity and toughness, but strength and toughness is contradictory.

    The thread at both ends of the thread rods is a whole set of drilling tools, it' s the key part of rod.

    It is well known that the performance of the material could be played well only after going through heat treatment to release its maximum potential, therefore, the choice of material and heat treatment process are important on an equal basis.
