Wholesale API steel tooth tricone rotary roller rock drill bit in stock based on the lowest quotation and excellent quality from China supplier Bit Description: IADC: 216 - Steel tooth sealed roller bearing bit with gauge protection for medium to medium hard formations with high compressive strength. Compressive Strength: 0 - 35 MPA 0 - 5,000 PSI Ground Description: Very soft, unstratified, poorly compacted rocks such as poorly compacted clays and sandstones, marl limestones, salts, gypsum, and hard coals. We can offer mill tooth and TCI tricone drill bits in a variety of sizes (from 3 ” to 26”) and most of IADC Codes.
According to cutting material,three cones bit can be divided into TCI bit and Milled Tooth Bit 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 | |

6 3/4" Tricone Bits is a regular diameter for HDD pilot hole, this model has 3 lateral jet nozzles, the hydraulic performance is better than central jet hole in clearing rock chips especially in drilling sticky rocks. The steel teeth tricone bit has a central hole which is suitable for RC drilling( Reverse Circulation drilling). IADC216 tricone bit could drill harder formations than IADC126, choosing the proper IADC according to hardness of rocks is the first step of high efficiency drilling.6 3/4" Tricone Bits is a regular diameter for HDD pilot hole, this model has 3 lateral jet nozzles, the hydraulic performance is better than central jet hole in clearing rock chips especially in drilling sticky rocks.
