(2)Product features
1. Matrix PDC bit with four ⁄ five⁄ six ⁄ seven ⁄ eight blades of medium parabola crown profile and with medium cutter density.
2. Spiral gauge protection design reduces vibration severity.
3. With interchangeable screw nozzles.
4. Asymmetrical blades arrangement and special load-balanced cutter arrangement design improve.
5. Non-plane interfaced diamond⁄ carbide cutters absorb effectively high stress and minimize cutter fracturing and wearing.
6. Both tilted and cauterized nozzles design improves bit cleaning and prevents bit balling, thus to improve ROP.
7. Can be used on rotary or down hole motor drilling.
8. Suitable for soft to medium hard formation.
9. High HIS is recommended.
