Wholesale API TCI tricone rock drill bits in the stock from China factory for the hard formations. Bit Description: IADC: 627 - TCI journal sealed bearing bit with gauge protection for medium hard formations with high compressive strength . Compressive Strength: 100 - 150 MPA 14,500 - 23,000 PSI Ground Description: Hard,well-compacted rocks such as: hard silica limestones,quarzite streaks,pyrite ores,hematite ores,magnetite ores,chromium ores,phosphorite ores and granites. FAR EASTERN DRILLING can offer TCI bits in avariety of sizes (from 3 3/8" to 26") and all most of IADC codes.
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 | |
