Deep Well Tricone Bit IADC517 7 7/8 inches (200mm)
Product Description
Far Eastern have 15 years services experience to supply the drill bits and advanced drilling soulutions for oil field,natural gas,geological exploration, driectional boring,mining, water well drilling, HDD, construction, and foundation. Our drill bit include tricone bits, PDC bits, HDD hole opener, Foundation roller cutters.
Reduce drilling cost, speed the drilling,guarantee the safety is our aim.
According to cutting material,tirocne bit can be divided into TCI bit and Steel Tooth Bit .API TCI tricone bit. iIADC517 7 7/8" (200mm) have type of Rubber/Elastomer sealed bearing and Metal sealed bearing. We suggest that we had better choose metal face sealed bearing bits for deep rock wells with hard formations.For very deep well drilling, we recommend Metal-face sealed bearing tricone bits in drilling depth exceeds 1000 meters, for hard rock and long distance trenchless pilot hole drilling that length exceeds 300 meters we also recommend metal-face sealed bearing tricone bits.For water well drilling, shallow well drilling or shorter distance trenchless pilot hole drilling projects, elastomer(rubber) sealed bearing tricone bits has better cost performance.
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.
Choose the proper rocks drilling bits is very important before starting project. Mostly IADC517 is for drilling soft rocks and IADC637 is for drilling hardest.

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.
