Description
Features
Deep blade and medium 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.
Spiral Blade
Double rows spiral four blades design,allows greater borehole coverage and better cutting structure,maximized enhances wear resistance and stability of the bit.
Enhanced Gauge
Enhanced gauge with high quality PDC
cutters, offers additional protection in abrasive applications, helps several- -fold increasing wear resistance and life 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.
