In addition, art manufacturing technology makes our DTH bits with higher and more reliable quality.


    Advantage:


    1. Valveless air distribution, more reliable.

    2. Piston with simple but compact design, long life.

    3. More efficient energy transfer, faster-drilling speed, lower air consumption, and lower oil consumption.

    4. Fewer internal parts, simple structure, longer life, less failure, and easier to maintain, with all heat-treated parts;

    5. Easy to disassemble, thanks to the top sub, drive chuck and external cylinder all are connected by a multi-step thread.


    Application:


    1. Suitable for high-pressure drilling rigs.
    2. Water well drilling.
    3. Record-breaking penetration.
    4. Exploring Civil Engineering Applications.
    5. Lowest cost per foot drilled.
    6. Simple & robust design.
    7. Exploring Civil Engineering Applications.
    8. Foot Valve not required in the bit.
    9. Longer parts of life.
    10. Maximizes efficiency.

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


    Drop Center

    For high penetration rates in soft to medium-hard and fissured rock formations.
    Concave Face
    The all-round application bit face is 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 an 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.


    Features of our Threaded Button Bits:
    * Be produced from premium quality Nickel-alloy steel or Molybdenum-ally steel for increased durability and wear characteristics
    * Specific heat treatment standards and strict production process ensure consistent performance
