Wholesale API water well tricone rock drill bits IADC537 with elastomer sealed bearing for hard formmation in stock with discounted price from China factory.Sealed bearing tungsten carbide insert tricone bits is one of the required drilling tools in water well drilling especially the rocks is hard, complex and tough.Connected with drill pipes drived by rotary table or hydralic rigs, the tungsten carbide drills rocks by horizontal cutting and vertical shocking, the two motions compose together at high efficience. Far Eastern Drilling can offer tricone bits in a variety of sizes (from 3” to 26”) and most of IADC Codes.Choose the proper rocks drilling bits is very important before starting project. Rocks hardness could be soft, medium and hard or very hard, hardness of one type of rocks may be also a little different, for example, limestone,sandstone, shale has soft limestone, medium limestone and hard limestone, medium sandstone and hard sandstone, etc. With fast delivery time and warm after-sale service, China Far Eastern has serviced for mroe than 35 countries in past 10 year In drilling project, We have experience to supply the drill bits and advanced drilling soulutions for many different applications. The application including water well drilling oil field,natural gas,geological exploration,driectional boring ,The various drill bits can be customized as per different rock formation becasue we have our own API & ISO certified factory of tricone 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.
