Steel Body PDC Drill Bit obtains better ROP in soft to medium hard formations and lower compressive strength.



  1. Durasef Gauge: Super strong material promotes gauge wear resistance to enhance long lifetime.
  2. Hydraulics: The movement and cooling of cuttings can be optimized by the hydraulic design that matches the chip quantity and displacement of each blade.
  3. Special Backrake Design: A Backrake can be added in the bit in order to prevent the bit from getting stuck when drilling.



  1. Unique Blade Design: Importing exclusive cutting teeth and unique curved blade design improve the ability of drilling in hard interlayer.
