Key Features of Steel PDC Drill Bits

The Steel body PDC bit is manufactured from high-grade 4145H round steel, offering a cost-effective alternative to matrix body bits without sacrificing performance.

  • Ultra-High Wear-Resistant Cutter: Diamond layer thickness (2.0-3.0mm) provides 2.5x higher wear resistance.
  • Impact-Resistant Design: Arc transition + surfacing reinforcement increases toughness by 30%.
  • Versatile Application: Ideal for abrasive formations with quartz content ≤ 35%.
  • Customization: Supports diameters from 4" to 26" and 3-8 blade configurations.
