Matrix Body PDC Drill Bit is suitable for medium hard and hard formations with optimized crown profile and cutters layout. It can achieve better performance in deep intervals. Long service life and high performance help reduce the drilling cost.



  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



  1. Unique Blade Design: Importing exclusive cutting teeth and unique curved blade design improve the ability of drilling in hard interlayer.
  2. The formula of matrix powder: independent intellectual property rights and advanced sintering technology have made the mechanical properties of matrix reach the international advanced level. The blade of the matrix drill can be designed to be deeper and narrower. It can completely satisfy the complex drilling operation in the well.
