1. Bearing Structure: High precision journal bearing with two thrust faces. Ball locked cone. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved, and suitable for high rotary speed.
2. G-Gauge protection: 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.
3.Cutter: premium carbide teeth having increased resistance to breaking and abrasion, maximum increase cutting structure operating life.
4.Nozzle：These nozzles are much sturdier and provide greater flow capacity and maximize fluid distribution to the cones.
--The first-class engineers of tricone bits and PDC bits
--Advanced technology and Equipment, International standard.
--R&D center for rock drilling tools, high precision CNC machines, SGS&ISO Certified.
--10+ Years & 40+ Countries service experience.
--Optimized solutions for various of requirement
