12 1/4'' Carbide Tricone Drill Bit Water Well Drilling High Wear Resistance

 

Product description
 

  • The strength and wear resistance of inserts are improve by using carbide inserts with high strength and high wear resistance.
  • 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.
  • The service life of the bearing is further extended by adopting harder and more wear resistant material for thrust bearing.
  • 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.
  • Thrust bearing surfaces are hard faced and treated with friction reducing technology.
  • 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.
