•Deep blade and long parabolic configuration design,ensures optimal bottom hole flow pattern
and anti-balling.
•Optimize the cutting structure and places high quality cutters at different points, increases wear resistance and offensive of the bit.
•Anti-whirl design improves ROP and enhances the drilling stability.
Description
Additional Row
Double rows five blades design,maximized enhances wear resistance and stability of the bit.
Gauge
Unique gauge with high quality PDC cutters, helps several-fold increasing wear resistance and stability of the bit.
Hardfacing
The surface of the blade is welded by wear-resistant hardfacing material, improves wear resistance and erosion resistance of the bit.
