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
