Description
Features
Deep blade and short 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 drilling stability.
Spiral Blade
Double rows spiral eight blades design,allows greater borehole coverage and better cutting structure,maximized enhances wear resistance and stability of the bit.
Extended Gauge
Extended gauge provides stable dilling without losing steerability and drilling with low torsional loads, Improves a high quality borehole.
Hardfacing
The surface of the blade is welded by wear- -resistant hardfacing material, improves wear resistance and erosion resistance of the bit.
