Whether you are drilling a water well or an oil well, Lockheed has the tricone drill bit for you.  TCI(Tungsten Carbide Insert) tungsten carbide roller bitsTCI(Tungsten Carbide Insert). These tricones are designed for soft to very hard formations depending on the style and quantity of the carbides on the drill bit. Because of its versatility and performance, it's still one of the main Rock Bits in use today. It is widely used for oil&gas, water well, geotechnical, environmental, geothermal, construction, exploration and mining drilling. >BEARINGSPrecision bearings made with the tightest tolerances in the industry! The bearing materials used have extremely low friction and high load capacity. Chemically heat resistant, heat tolerant HNBR materials for bearing seal and pressure compensator. This material is very compatible with oil based muds air cooled and open bearings are also available.>REMING GAUGE:Put more active cutting elements on gauge than anyone in the industry. Perfect for directional applications. Its gauge holding ability is superior for maintaining gage on lateral or extreme build angles. We can offer diamond in this feature for the most abrasive applications. Bearing and seal life are extended by keeping the cone from rubbing the hole-wall and generating additional heat.>ENHANCED HYDRAULICS:Design flexability offers customers the ability to effectively clean the cutting structure, while minimizing cone erosion. Premium nozzles are used for consistentcy and reliability.FormationUsed inCommon IADCSoftClays, coal, salts, shales, soft limestone,discontinuous sands etc...417,437MediumSedimentary rocks, limestone, sandstone,slate etc...517,537HardVarieties of silica, basalt, dolomite, compactsands, limestone etc...617,637,737Ultra HardMarble, quarzite, granite, gneiss, pyrite, etc...837Sealed Bearing tci tungsten carbide roller bits with or without gauge protectionThese are the best preforming and longest lasting style of tricone on the market. Sealed bearings will out perform open bearings. Gauge protection greatly increases the life of the drill bit. Open Bearing tci tungsten carbide roller bits with or without gauge protectionOpen bearing tricones can be gauge protected or not. These tricone bits have exceptional value, good performance and low cost. Gauge protection greatly increase the life of the drill bit.ModelSteel tooth tungsten carbide roller bits ,   tci tungsten carbide roller bitsIADC Code116 117 126 127 136 137 216 217 226 316 317 326 327 336 337 115 125 135 215 225 235 315 325 335 114 124 214 314 111 121 131 346 347417 427 437 517 527 537 617 627 637 737 837 832 415 425 435 445 525 625 635 416 427 436 446 447 516 526  537 547 516 536  535Bearing TypeH---Friction bearing; G---Roller bearing; F--- Floating BearingSealing TypeHJ(metal sealed journal bearing)HA (rubber sealed journal bearing)  air cooled bearing typeSizeFrom 2 7/8" to 26" larger sizes for hole opener bit ,reamer bitMaterialalloy steel, tungsten carbide insertExtra Feature1) Y-Conical teeth  2) X-chisel teeth 3) K- wide teeth 4) G- Gague protectionApplicable FormationVery soft, soft , medium soft ,hard, medium hard, very hard formationApplicationPetroleum & gas ,water well ,mining and tectonic industries ,oil field, construction, geothermal, directional boring, and underground foundation workPackageSeaworthy packing wooden case or as your requirementPayment TermT/T, L/C at sightLead Time3-7 work daysDelivery WayBy sea or by airAll sizes and IADC codes of drill bits are available.
