Mainly consists of four or more cones2. Suitable for different complexes formation3. The pilot is tricone bitCone bit, reamer bit, hole opener bit, bigger diameter bit. 1. Cutting StructureThe reamer mainly consists of four or more cones. Cutting Structure with premium tungsten carbide hardfacing or premium tungsten carbide insert of formulas and new techniques is utilized, and increases wear-resistance capability of reamer. The pilot is three cone bit( tricone bit ). 2. Seal and LubricationHigh performance HNBR O-ring for bearing seal and advanced grease for lubrication. 3. Product ApplicationIt is suitable for the large size well, mining and infrastructure applications. Drill bit introduce1. Drill bit cutting structureAdopting new formula of new technology of the high quality hard alloy tooth, enhance the cutting teeth mechanical properties. 2. Drill bit diameter structureUsing multiple gage protection structure: Die with multidrug trimming tooth (GT teeth), round back, claw back set have cemented carbide gear, surfacing resistance mo alloy, strengthen ZhaoJian and anterior apply welding, greatly improving the drill gage protection ability. 3. Drill bit bearing structureAdopting high precision with radial sliding, two way thrust bearings, ball tight. Tooth claw big shaft neck and two stop surface welding have wear-resisting alloy, cone big hole and two stop surface solution and silver inlaid special alloy, increase the abrasion resistance and resistance bearing vice occlusive ability, improve bearing ability of high speed vice adapt. 4. Drill bit seal lubricantsAdopting advanced metal seal, greatly extend the drill life. 5. Drill bit applicableMetal seal bit stable performance, than common rubber seal bit longer life, suitable for underground power drill and high penetration rate turntable drilling.Available sizes:60mm, 65mm, 76mm, 93mm, 95mm, 98mm (3 7/8" ), 101.6mm, 114mm, 118mm, 120mm, 127mm(5" )130.1mm(5 1/8" ), 133.3mm (5 1/4" ), 139.7mm(5 1/2" ), 142.8mm (5 5/8" ), 149.2mm (5 7/8" )152.4mm (6" ), 155.5mm(6 1/8" ), 158.7mm(6 1/4" ), 161.9mm(6 3/8" ), 165.1mm (6 1/2" )190.5mm (7 1/2" ), 193.6mm (7 5/8" ), 200.0mm (7 7/8" )212.7mm(8 3/8" ), 215.9mm (8 1/2" ), 222.2mm(8 3/4" )241.3(9 1/2" ), 244.4(9 5/8" ), 250.8(9 7/8" )269.8(10 5/8" ), 295.3(11 5/8" )311.1(12 1/4" ), 346.0 (13 5/8" ), 349.2(13 3/4" )374.6(14 3/4" )381(15" ), 393.7(15 1/2" ), 406.4(16" )444.5(17 1/2" ), 508(20" ), 558(22" ), 609.6(24" )660.4(26" )Available models:Steel tooth(IADC code)111, 121, 131117, 124, 126, 127, 136, 137211, 311216, 217, 227TCI(IADC code)415, 435, 417, 437515, 525, 535, 545, 517, 527, 537, 547615, 625, 635, , 617, 627, 637, 737512, 522, 532, 612, 622, 632, 732
