PRODUCTS DETAILS

The tricone rock bit for cement and bridge plug is always steel tooth tricone bits, the bearing quality is requested to be very long working life, and the tooth arehard-faced by premium tungsten carbide powder. Far Eastern drilling have 15 years to produce the drill bits. We have exported more than 30 countries services experience to supply the drill bits and advanced drilling soulutions for many different application such as field well drilling,natural gas well drilling,geological exploration well drilling,driectional boring,water well drilling ,We can OEM drill bits as per different rock formation. We get API & ISO certificate of tricone drill bits and PDC drill bit. We can give our engineer's solution when you can supply specific conditions, such as hardness of rocks,types of drilling rig,rotary speed,weight on bit and torque.

table
Tricone 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. Characteristics 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. 5. Thrust bearing surfaces are hard faced and treated with friction reducing technology. 6. 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.
