Wholesale API rotating head for drilling rig in stock based on the lowest quotation and excellent quality from China factory Bit Description: IADC: 127 - Steel tooth journal sealed bearing bit with gauge protection for soft formations with low compressive strength and high drillability. 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 Milled tooth tricone bit IADC127 is for very soft 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 | |

8 1/2 inches milled tooth bit IADC127GT is a regular size with Edge-Row inserts in water well drilling, it is working well with small capacity drilling rigs and widely used in the world. The feature of IADC code GT means TCI protection on shirttail of arms(legs), T means TCI teeth on edge row of cones. With the feature letter T, steel tooth tricone bit can drill soft rocks without concerning of shrinking Steel tooth tricone rock bit is also named milled tooth tricone rock bit could drill soft mudstone, even soft limestone, the cones are hard faced by tungsten carbide, the bearing is journal and locked by ball, high grade elastomer(rubber)-HNBR O-ring sealed bearing, grease compensating system lubricate the bearing , the working life is very long.
