Description
The main structure of features:
Steel Tooth Hardfacing Trimming teeth are arranged between the gauge compact and the outer row teeth, thereby reducing the abrasion between the back cone teeth and the cone shell, optimizing the shape of the teeth, reinforcing the surfacing material, and raising the rate of penetration by more than 15%. High Efficency Drilling The tooth are arranged at unequally spaced intervals, and the design for the number of the teeth and the height of the exposed teeth is optimized to enhance the rock-crushing capacity in the central areas of the drill bits and the self-centering capacity, and improve the rate of penetration by 10%. Jet The enhanced main water pore can effectively protect the drill bits from being eroded by the mud fluid of each jet direction and improve the water-horse power of the single jetting, pumping jetting, pulse jetting, and skew jetting or reverse jetting by using the patented technology of us (the Patent No. is ZL96221141.9) under various drilling technology conditions. Enhanced HydraulicsThe optimal hydraulic design enhances cross-flow speed in the down hole, and effectively raises the rate of penetration. A central nozzle is arranged in the drill bit with a large diameter to strengthen the cleaning to the bit teeth and effectively protect the drill bit from bit balling.
