Product Description
Far Eastern Drilling are API (API-7-1 & API Spec Q1) factory specializes in drill bits, such as Tricone Bit,PDC Bit,Hybrid Bit,HDD Hole Opener,Foundation Roller Cone Bits and related drilling tools,application fields includes for oil well drilling, gas well drilling, geothermal well drilling, mining, geological survey, hydrographic survey, water well drilling, HDD pipelines installation projects, foundation rock piling projects. We can offer both TCI and Steel (Milled) Tooth in a variety of sizes and all most of IADC codes in stock.Bearing Structure:High precision roller bearing with two thrust faces,Ballk lock the cone,.The leg bearing can get larer by arraning the roller in groove of the cone hole,so it can receive more Wob,and suitable for high RPM.Thrust faces hardfaced with wear resistant alloy,Abrasion resistance and seizure resisitance of the bearing are inproved.

5. Do you have Referenced Letters /Recommendation Letters from old customers?
Answer: Yes, we have many referenced letters/recommendation letters issued by old customers who would like to share our stories.
Cutting Structure :The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.The durability of premium tungsten carbide inserts is improved with newformulas and new techniques for insert bit.
Gauge Structure:Multiple gauge protection with gauge trimmers on the hell andgauge inserts on the gauge surface of the cone,tungsten carbide inserts and hardfacing on the shirttail increases gague holding capability and bearing life.
Bearing Structure:High precision roller bearing with two thrust faces,Ballk lock the cone,.The leg bearing can get larer by arraning the roller in groove of the cone hole,so it can receive more Wob,and suitable for high RPM.Thrust faces hardfaced with wear resistant alloy,Abrasion resistance and seizure resisitance of the bearing are inproved.
Sealand Lubrication:Premium HNBR O-ring,optimal seal compression and curved seal structure can enhance seal performance. The pressure compensator system and adwanced grease can greatly increase the lubricating reliability.
Product Application:It can receive higher WOB and faster rotary speed than conventional roller bearing bits.It is suitable for high POM applications.
