Choose the proper rocks drilling bits is very important before starting project.
For very deep well drilling, we recommend Metal-face sealed bearing tricone bits in drilling depth exceeds 1000 meters, for hard rock and long distancetrenchless pilot hole drilling that length exceeds 300 meters we also recommend metal-face sealed bearing tricone bits.
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,water well drilling ,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.
