Tricone bit can devide into milled tooth bit and TCI bit based on the different cutting material. TCI is the meaning of tungsten carbide insert.Steel tooth bit also call milled tooth bit. TCI bit adopts high-strength and high-toughness hard alloy teeth, optimized design of tooth row number, tooth exposure height,tooth number,unique alloy tooth shape,giving full play to TCI bit's high wear resistance and excellent cutting ability.New wear-resistant material is applied to weld the tooth surface of the Steel tooth bit, which can maintain the high penetration rate of the Steel tooth bit and improve the life of the cutting tooth of the bit. According to the type of bearing, the tricone rock bit can be further divided into metal seal bearing and rubber seal bearing.

In drilling project, Far Eastern have 15 years and more than 30 countries services experience to supply the drill bits and advanced drilling soulutions for many different applications. The application including oil field,natural gas,geological exploration,driectional boring,mining ,water well drilling ,HDD, construction,and foundation.The various drill bits can be customized as per different rock formation becasue we have our own API & ISO certified factory of drill bits. 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. It is also hlep us to find the siutable drill bits after you can tell us vertical well drilling or horizontal drilling ,oil well drilling or No-Dig drilling or foundation piling. Far Eastern are factory specializes in drill bits,such as tricone bits, PDC bits, HDD hole opener,Foundation roller cutters for different applications. As a leading drill bits factory in China,increase the drill bit working life is our target. We always try to improve the bits with high penetration rates.Our purpose is to sell the high quality with the lowest price.
