    Rock Bit Series

    Our mineral Rock bit products are used in air drilling, such as the development of iron ore, non-ferrous metal ore and open pit mining tools. The products mainly cover 6" - 17 1/2" and other size series, and in various specifications of mining drill products, effectively improving the quality and performance of the drill.
    The single rock bit is a kind of deceleration bit, meaning the speed of the tooth is smaller than that of the drill bit. It is mainly used for cutting and broken rock, which is suitable for small drilling operations such as window side drilling and deep drilling under high speed and high drilling pressure.

    Wide Application Field

    Not only suitable for side drilling construction, but also can be used in medium and deep parallel drilling.

    Lower Working Torque

    Operates under lower torque than PDC drill bits under the same pressure, reducing tool expansion and avoiding downhole accidents.

    Hybrid Advantages

    Combines the benefits of three-cone rock drills and PDC drills. More suitable for plastic formations and complex strata with hard interlayers.

    High Speed & Special Needs

    Cooperates efficiently with downhole power tools to achieve high rotation speed and meet customized drilling requirements.

    • Dimensions: 3 3/4" (95.3mm) - 6 1/8" (155.6mm)
    • Models: YA / YC 437, YA / YC 517, YA / YC 537

    Combination Bit Series

    The combined Bit Series are mainly used in bridges and high-rise bored pile bedrock drilling, railway, water conservancy, construction and other systems, trusted by the majority of users.
    Suitable for perfusion bedrock drilling, well and ventilation hole drilling. It is adapted to strong, medium and slightly weathered rocks and gravel, such as granite, gneiss, sandstone, limestone, shale, etc.

    Hydraulic Engineering Principle

    Designed specifically to effectively remove sediment at the bottom of the hole during operation.

    Double Fulcrum Rock Tooth

    Features the first double fulcrum rock tooth design in China for enhanced drilling stability.

    Wear Prevention Mechanism

    Equipped with a protective mechanism on the back of the palm to prevent premature wear and tear.

    Optimized Tooth Distribution

    Features a unique and highly reasonable distribution mode of the rock tooth for maximum cutting efficiency.

    Protective Cylinder Block: Further enhances the stability of the drill bit and extends its operating life. The PZ series combination rock tooth bit possesses the following properties: Sharp nature, wear resistance, robustness, stability, slag accumulation prevention, self-cleaning, and high safety.

    Frequently Asked Questions (FAQ)

    What are the primary applications for the Rock Bit Series?
    Our rock bit series are mainly designed for air drilling applications, including the development of iron ore, non-ferrous metal ore, open-pit mining tools, window side drilling, and deep drilling under high speed and pressure.
    What sizes and models are available for the single rock bit?
    The single rock bits are available in dimensions ranging from 3 3/4" (95.3mm) to 6 1/8" (155.6mm). The available models include YA / YC 437, YA / YC 517, and YA / YC 537.
    What makes the single rock bit better than a standard PDC drill bit?
    Under the same drilling pressure and formation conditions, the single rock bit runs at a lower working torque. This reduces small-size drilling tool expansion, prevents downhole accidents, and manages hard interlayers or complex strata better than PDC bits.
    Which rock formations are suitable for the Combination Bit Series?
    The Combination Bit Series is highly adapted to strong, medium, and slightly weathered rocks and gravel, including granite, gneiss, sandstone, limestone, shale, and other complex formations.
    What are the key design features of the combination tooth wheel drill bit?
    Key features include a hydraulic engineering design for bottom-hole sediment removal, the first double-fulcrum rock tooth design in China, a wear prevention mechanism on the back of the palm, an optimized rock tooth distribution, and a protective cylinder block.
    What properties does the PZ series combination rock tooth bit offer?
    The PZ series is characterized by its sharp nature, superior wear resistance, robustness, operational stability, effective slag accumulation prevention, self-cleaning capabilities, and overall safety.
