Application   1. The strength and wear resistance of inserts are improve by using carbide inserts with high strength and high wear resistance. 2. Surface of the high precision bearing heat treated by using advanced heat treatment process to improve the load capacity and service life of the bearing. 3. The service life of the bearing is further extended by adopting harder and more wear resistant material for thrust bearing. 4. 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 hard faced and treated with friction reducing technology. 7. Rotary drill bits use journal bearing. Hard faced 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 improve. Guidance of Tricone Bit Choice

4 1/2 Inch Water Well Roller Cone Bit 114mm Steel Tooth Tricone Bit The tricone drill bit is the most popular drilling bit in the world,it can be widely used for Oil&Gas Drilling,Mining,Water Well,Geological Exploration areas.Our tricone bit divideds into metal sealed drill bit and rubber sealed bit. 1. The C-Center jet can avoid the formation of a ball in the bit, eliminate the fluid area at the bottom of the well, accelerate the upward flow of drilling cuttings and improve ROP. 2. High saturation NBR bearings can reduce sealing pressure and improve sealing reliability. 3. The G-Gauge protection improves the measuring ability and prolongs the service life of the bit. 4. Adding a row of teeth between the rear taper and the outflow to trim the borehole and protect the cone.
