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.
