1. Ehanced hardfacing for mill tooth with proper tenacity
2. Sharp tooth highly increase the footage
3. ISO9001 certificate
4. Strong wear resistant teeth and high ROP, more stably, suit for drilling 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 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.Hebei Crossing Drill Bit Manufacture CO.,LTD is a professional supplier of drilling tools,including tricone bit,PDC tricone bit,Hole opener,single cone bit and so on.With years of study and refining of the introduced technology, we have succeeded in the field of product research with proprietary intellectual property rights.Also, we have made major breakthrough in the lines of analogue simulation in bottom-hole flow field,profile optimization,design of inserts arrangement and low torque,material and manufacturing techniques etc. As a result, our products own better characters of service and ranges of application.Mainly used for oil and gas,mining,geothermal,construction and so on.
