Steel PDC Drill Bit
The entire bit body of the PDC steel bit is made of medium carbon steel and machined using a fabrication process. The bit crown is treated with a surface hardening process (sprayed tungsten carbide wear layer, carburized) to enhance erosion resistance.

Steel PDC Bit Performance
The drill head is treated with the surface hardening process (spraying tungsten carbide wear -resistant layer) to enhance its erosion resistance. The advantage of steel body is that the manufacturing cost is low and easy to repair.
