API Factory of Oilfifeld Tricone Bit for Oil/Gas/Geothermal/Mining/Water/Geological Survey/Hydrographic Srve/HDD Well Drilling in Stock

Far Eastern Drilling are API (API-7-1 & API Spec Q1) factory specializes in drill bits, such as Tricone Bit,PDC Bit,Hybrid Bit,HDD Hole Opener,Foundation Roller Cone Bits and related drilling tools,application fields includes for oil well drilling, gas well drilling, geothermal well drilling, mining, geological survey, hydrographic survey, water well drilling, HDD pipelines installation projects, foundation rock piling projects. We can offer both TCI and Steel (Milled) Tooth in a variety of sizes and all most of IADC codes in stock.According to cutting material,tirocne bit can be divided into TCI bit and Steel Tooth Bit .TCI is short for Tungsten Carbide Insert, tungsten carbide is regular hard material in rock drilling field, another material is diamond.Inserts means Tungsten Carbide teeth that's fitting on cones of rotary drilling roller cone bits. .API TCI tricone drill bit IADC537 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. Bit Description:IADC:537-TCI journal sealed bearing bit with gauge protection for soft to medium soft formations with low compressive strength.Compressive Strength:85-100 MPA12,000-14,500PSIGround Description:Medium hard and abrasive rocks such as sandstones with streaks of quartz,hard limestone or chert,hematite ores,hard,well-compacted abrasive rock such as:sandstones with quartz binder,dolomites,quartzite shales, magma and metamorphic coarse grained rocks.Basical SpecificationSize of Rock Bit12 1/4 inches311.1 mmBit TypeTCI Tricone BitThread Connection6 5/8 API REG PINIADC CodeIADC 537GBearing TypeJournal Sealed Bearing with Gauge ProtectionBearing SealElastomer/Rubber or MetalHeel ProtectionAvailableShirttail ProtectionAvailableCirculation TypeMud CirculationDrilling ConditionRotary drilling,high temp drilling deep drilling, motor drillingNozzlesThree NozzlesOperating ParametersWOB (Weight On Bit) KN/mm0.35-0.9RPM(r/min)50-120FormationMedium formation with low compressive strength ,such as medium,soft shale,medium soft limestone,medium soft limestone,medium soft sandstone,medium formation with harder and abrasive interbeds,etc.     Steel (Milled) Tooth Bit             IADC CodeIADC111,IADC114,IADC115,IADC116,IADC117,IADC121,IADC124,IADC125,IADC126, IADC127,IADC131,IADC135,IADC136,IADC137,IADC214,IADC216,IADC225,IADC226, IADC235,IADC237,IADC314,IADC315,IADC316,IADC317,IADC325,IADC326,IADC327, IADC335,IADC336,IADC337,IADC347    Tungsten Carbide Insert       (TCI) Bit IADC CodeIADC417,IADC427,IADC437,IADC517,IADC527,IADC537,IADC617,IADC627,IADC637, IADC737,IADC837,IADC832,IADC415,IADC425,IADC435,IADC445,IADC525,IADC625, IADC635,IADC412,IADC415,IADC416,IADC422,IADC425,IADC427,IADC435,IADC436, IADC446,IADC447,IADC516,IADC526,IADC532,IADC535,IADC536,IADC542,IADC545, IADC547,IADC615,IADC622,IADC632,IADC635,IADC642,IADC645,IADC715,IADC722, IADC725,IADC732,IADC735,IADC742,IADC745,IADC825,IADC832,IADC835,IADC845Available SizesFrom 2 7/8 inches to 26 inches larger sizes for the hole opener bit ,reamer bitAdvantageMost favorable price and best qualityBearing TypeSealed bearing / non-sealed bearing / Metal sealed bearing / Rubber sealed journal bearing / Air cooled bearing Layer DetailsSoft,medium soft, hard ,medium hard, very hard formationButton Size/Extra FeaturesButton bit teeth:1) Y-Conical teeht 2)X-Chisel teeth 3)K-Wide teeth       4)Spoon tooth 5)Spherical ToothMaterialAlloy steel ,Tungsten of CarbideApplicationoil well drilling, gas well drilling, geothermal well drilling, mining, geological survey, hydrographic survey, water well drilling, HDD pipelines installation projects, foundation rock piling projects.  Bit SizeAPI REG PINTorqueWeigtINCHMMINCHKN.MKGS3 3/885.72 3/84.1-4.74.0-6.03 1/288.94.2-6.23 7/898.44.8-6.84 1/41085.0-7.54 1/2114.35.4-8.04 5/8117.52 7/86.1-7.57.5-8.04 3/4120.77.5-8.05 1/8130.23 1/29.5-12.210.3-11.55 1/4133.410.7-12.05 5/8142.912.6-13.55 7/8149.213.2-13.56152.413.6-14.56 1/8155.614.0-15.06 1/4158.814.4-18.06 1/2165.114.5-20.06 3/4171.520.0-22.07 1/2190.54 1/216.3-21.728.0-32.07 5/8193.732.3-34.07 7/8200.0 33.2-35.08 3/8212.738.5-41.58 1/2215.939.0-42.08 5/8219.140.5-42.58 3/4222.340.8-43.09 1/2241.36 5/838-43.461.5-64.09 5/8244.561.8-65.09 7/8250.862.0-67.010254.0 68.0-75.010 1/2266.772.0-80.010 5/8269.972.0-80.011 1/2292.179.0-90.011 5/8295.379.0-90.012 1/4311.295.0-102.012 3/8314.396.0-103.012 1/2317.597.0-104.013 1/2342.9105.0-134.013 5/8346.1108.0-136.014 3/4374.77 5/846.1-54
