High-Performance Drill Bits from China: Leading Suppliers and Factory for Precision Engineering and Mining Solutions
Rock Bit Series
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
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.
