1. Ehanced hardfacing for steel tooth with proper tenacity
2. Sharp tooth highly increase the footage
3. ISO9001 n API certificate
4. Strong wear resistant teeth and high ROP, more stably, suit for driling in soft formation with fast rotary speed.
5.This series oil well rock bit use Sealed roller bearing structure. With rollers arranged in grooves recessed in the cone body, the size of the bearing journal is increased.
6. Thrust bearing surfaces are hardfaced and treated with friction reducing technology.
7. This series oil well rock bit use Journal bearing. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. The load capacity and seizure resistance of the bearing is greatly improved.
