Steel Tooth Tricone Bit

Cutting Structure The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit. Gauge Structure Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life. Bearing Structure High precision roller bearing with two thrust faces. Ball lock the cone. Thrust faces hardface with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved. Seal and Lubrication Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability. Product Application It is suitable for various formations, and achieves high RPM under low to medium WOB applicationAvailable 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” )
