Steel Body PDC Drill Bits: The bit body is constructed from high-quality 4145H round steel, offering a more cost-effective solution compared to matrix body bits while maintaining exceptional performance.

Ultra-High Wear-Resistant Cutter Technology: Featuring an independently optimized diamond layer (2.0 to 3.0 mm thick), providing 2.5 times higher wear resistance than industry standards. Achieve drilling footage up to 8,300 meters in abrasive formations.

Impact-Resistant Design: High-strength alloy steel with arc transition and surfacing reinforcement increases impact toughness by 30%, eliminating blade cracking in gravel interbeds.

Flexible Customization: Support for non-standard diameters (4"–26") and variable blade counts (3–8 blades).

Applications

PDC bits are essential for various demanding environments:

  • Oil & Gas drilling
  • Geothermal drilling projects
  • Coal bed methane extraction
  • Hard rock mining operations
  • Water well drilling
  • Horizontal directional drilling (HDD)
