Micro Core Bit
Design for higher ROP in drilling deeper and harder formations, PDC drill bit always drills from ground to bottom directly with less or even a single run, saving large amount of drill time and cost .
Differ from tricone bit, PDC drill bit runs with lower WOB but Higher RPM, so it usually works with downhole motor to pick up rotating speed.
The performance of PDC drill bit depends a lot on PDC cutters, we provide unique solution to specific requirement on varied formations.
It is suitable for coring operations in medium and hard formation with long life time feature.
1.Unique Blade Design: Importing exclusive cutting teeth and unique curved blade design improve the ability of drilling in hard interlayer.
2. The high-quality composite: It effectively improves the performance and life of the drill bit. Cutting structure has strong aggressiveness.
3. The special layout: The special layout of the blade water hole improves the cooling and cleaning ability of the bit, and improves the efficiency of cuttings migration.
