Wholesale API TCI rotary diamond tricone rock drill bits in the stock from China supplier. Bit Description: IADC: 537 - TCI journal sealed bearing bit with gauge protection for soft to medium soft formations with low compressive strength . Compressive Strength: 85 - 100 MPA 12,000 - 14,500 PSI Ground Description: Medium hard and abrasive rocks such as sandstones with streaks of quartz, hard limestone or chert, hematite ores, hard, well-compacted abrasive rock such as: sandstones with quartz binder, dolomites, quartzite shales, magma and metamorphic coarse grained rocks. We can offer TCI bits in avariety of sizes (from 3" to 26") and all most of IADC codes.
According to cutting material,tirocne bit can be divided into TCI bit and Steel Tooth Bit . TCI IADC537 is for medium hard formation. 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. 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.| Basical Specification | |
