Introducing the 4-Wing PDC Drag Bit
Precision Drilling for Soft to Medium-Hard Formations with Minor Interbedded Layers
We are proud to introduce our latest innovation: the 4-Wing PDC Drag Bit, engineered for high-precision rotary drilling in soft to medium-hard formations (F<8) with minor interbedded layers. This advanced bit combines cross-symmetrical four-wing design with premium PDC cutters to deliver superior hole accuracy, operational stability, and extended service life.
⚙️ Design Philosophy: Cross-Symmetrical Four-Wing Structure
The cross-symmetrical four-wing cutting structure represents a significant advancement from traditional three-wing designs. This configuration provides superior radial stability, minimizing lateral vibration and ensuring consistent cutting performance throughout the drilling process.
- Even distribution of cutting forces across four wings
- Reduced radial runout for superior hole straightness
- Enhanced stability in formations with minor interbedded layers
🚀 Core Advantages
Cross-symmetrical four-wing structure minimizes radial runout, delivering superior hole verticality and roundness
Four wings evenly distribute cutting loads, reducing wing deflection and fracture risk in complex conditions
Premium PDC cutters with uniform placement reduce wear rate per wing, delivering longer footage than 3-wing bits
Available in 10+ standard sizes with full customization for thread types, cutter density, and structural parameters
