Tungsten carbide particle hardfacing is applied liberally along the shirttail and extended up the leading edge of the bit leg for additional protection in high-speed, directional or abrasive applications.
PDC bits can drill medium to medium hard strata. It is recommended to drill shale, mudstone, Cemented Sandstone and carbonate rock with medium compressive strength.
More tungsten carbide inserts are placed in the gauge to reduce the wear in the abrasive formation. It can protect gauge and increases the stability and life of the bit.
Deep blade and long parabolic configuration and deepen the maximum waterway. Optimize hydraulic design of the bit, significantly increases chip removal efficiency.
These Grand tungsten carbide insert bits are used to drill soft formation with low compressive strength and high drill ability, such as shale, clay, sandstone and soft limestone, etc.
Optimized flushing system including three combined nozzles, balances fluid flow, allows effectively cleaning bottom-hole zone and anti-balling.
