Water Well Drilling Tungsten Carbide Hard Rock 12 Inch Iadc537 TCI Roller Tricone Rock Drill Bits
TCI Roller Tricone Rock Rolling cutter bits, which some may also call roller cone bits or tri-cone bits, have three cones. Each cone can be rotated individually when the drill string rotates the body of the bit. The cones have roller bearings fitted at the time of assembly. The rolling cutting bits can be used to drill any formations if the proper cutter, bearing, and nozzle are selected.
We are a professional company in supplying tricone bits,steel teeth bits,single cone bits,and PDC bits.
Bits sizes range from 3 7/8” to 26”.and cover almost all IADC codes.It can be used in various of different fields,mining,hydrology,subterranean heatpilling,water well drilling and oil well drilling.This type of bits have optimal bearing design, it can be working stably in high WOB,and the qualtiy tungsten carbide inserts on cone and the gauge make a good wear resistance largely extend the working life of bits.It is suitable for medium to hard formation.
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.
