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.
