TCI tricone bit 1. Sizes range from 3 7/8" to 26" 2. Reliable bearing and lubrication system 3. Meet with API Spec7-1 Standard TCI tricone rock Bits, TCI bit, rock bit, TCI tricone bit, tricone bit, TCI tricone bit 1>Cutting Structure The durability of premium tungsten carbide insert is improved with new formulas and new techniques and new techniques. The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces. 2>Bearing Structure Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the probability of Cone-dropping to minimum. 3>Product Application It is suitable for the shallow well, water well and geothermal well Please specify the following on enquiry, Diameter IADC code Thread Connection Bearing structure Drilling formationSize 5 1/8” (130.1mm) IADC IADC613 Bearing Type Non-sealed journal bearing Thread Connection 7 5/8 reg pin WOB(KN/mm) 0.5~0.9 RPM(r/min) 100~60 Applicable Formations Medium hard formations with high compressive strength, such as hard shale, limestone, sandstone, dolomile, etc Circulation system Mud pump 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, 227 TCI(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
