    HDH360 DTH Drilling Bits For 3.5" Hammer


    Production Description:


    DTH hammer is a percussion system driving a piston inside a hammer body with up and down a motion by compressed air and transmitting intensive percussion energy to the bit to enable the drilling by crushing the rock. The drilling method by DTH hammer exerts high drilling performance especially for drilling hard rock and contributes to shortening the work schedule. Hence, this method is widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work.

    How to Select Threaded Button Bits Face shape and Carbide Button Shape

    A: Bits face shape selection

    Drop Center

    For high penetration rates in soft to medium-hard and fissure rock formations.
    Concave Face
    The all-round application bit face specifically for a medium-hard and homogeneous rock formation. Good hole deviation control and good flushing capacity.
    Convex Face
    For high penetration rates in soft to medium-hard with low to medium air pressure. It is the most resistant to steel wash, and good resistance to steel wash step gauge bit.
    Flat Face
    This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates and resistance to steel wash.


    B: Insert Carbide Button shape Selection
    The different button is ideal for different ground conditions, abrasive levels, and penetration levels. In general, the more gauge buttons, the better over performance, especially in hard rock.

    Spherical
    * Application Strength-multipurpose
    * Best suited to soft abrasive
    * 25,000 to 45,000 PSI (170 to 300 MPa)
    * Abrasive to very abrasive
    Ballistic Button
    * Application Strength- fast penetration
    * Best suited to soft ground
    * 10,000to 20,000 PSI(70 to 140 MPa)
    * Non-abrasive ground

    Semi-ballistic
    * Application Strength-fast penetration
    * Best suited to medium ground
    * 15,000 to 25,000 PSI(100 to 170 MPs)
    * Mildly abrasive ground

    Wedged (Conical) Button
    * Application Strength- fast penetration
    * Suited for all non-abrasive ground types
    * Smaller contact area
    * Best suited for smaller diameter bits
