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.

Weight On Bit(KN)
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
Six-point Gauge Stability
The design delivers near six-point contact with the borehole wall for unequalled bit stability that protects the cutting structure from damaging lateral blows
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.
The teeth are composed of premium tungsten carbide and some other elements, our engineer fine - tuned the compacts to match specific formations and dilingapplications.
Optimized flushing system including three combined nozzles, balances fluid flow, allows effectively cleaning bottom-hole zone and anti-balling.
