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 three 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.
The PDC bit is suitable for soft to medium hard formation. High HIS is recommended.
