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.
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.
Compared to roller cone bits, hybrid drill bits can increase ROP, requiring less weight on bit and minimizing bit bounce.
Optimized cutting structure, insert exposed height, quantity and shape strengthens the drilling coverage, giving full play to the advantages of trench-less reamer.
Kingdream make good R&D and finally have this good performance HDD reamer special bits. We can also supply Kingdream drilling bits, Kingdream tricone drilling bits and Kingdream all serial drilling bits for you.
The central core of the rock or concrete is usually crushed with a rock auger. The most important advantage of a core barrel is that it helps to Concentrate the torque and squeezing force on a small ring of cutting teeth.
Kingdream HDD bit have good performace and good price. We can also supply Kingdream drilling bits, Kingdream tricone drilling bits and Kingdream all serial drilling bits for you.
