Steel is metallurgically opposite of matrix. It is capable of withstanding high impact loads, but is relatively soft and, without protective features, would quickly fail by abrasion and erosion. Quality steels are essentially homogeneous with structural limits that rarely surprise their users.
Steel PDC bit with five blades of parabola crown profile and with middle cutter density
With interchan geable screw nozzles.
Asymmetrical blades arrangement and special load-balanced cutter arrangement design improve bit stability and therefore higher ROP
Non-plane interfaced diamond /carbide cutters absorb effectively high stress and minimize cutter fracturing and wearing.
Both tilted and cauterized nozzles design improves bit cleaning and prevents bit balling,thus to improve ROP
Can be used on rotary or down hole motor drilling
Suitable for soft to medium hard formation
High HIS is recommended
