Tungsten Carbide Tci Tricone Well Drilling Bit

TCI 437 Soft formation TCI Tricone bits The 437 tci bits are used to drill low compressive strength very soft formation tci bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design combined with maximum cone offset ,results in high bit penetration rates.the deep intermesh of cutter rows prevents bit bailing in sticky formations. TCI 517 medium formation TCI Tricone bits The 517 features aggressive chisel tungsten carbide inserts on the heel rows and inner rows this design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations the HSN rubber o-ring provides adequate sealing for bearing durability. TCI 617 TCI tricone bits 617 features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows .this design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations . the HSN rubber o-rin provides adequate sealing for bearing durability . TCI 637 can be used to drill hard and abrasive formations wear –resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. maximum numbers of hemispherical-shaped inserts are used in all rows to provide cutter durability and long life.

1.Tighten the bits when screw on. 2.When the bit lower down to the bottom , Should give a soft pressure, slow drilling .After a drilling 0.2m-0.3m with appropriate pump, then give the conventional drilling. 3.Drilling could not be without water, if not fear the normal vibration sound or drill too slow, lift the drill to check without delay. 4.When drill jammed, withdraw first, should not to force the rig start. 5.Drill could not without water, to ensure that the bit will be too hot. 6.Use the bits in right order , big size first, then small one . 30*35*40cm 45kg

1.Cutting structure this type TCI tricone bits: The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit. 2.Gauge structure this type TCI tricone bits: Multiple gauge protection with gauge trimmers on the heel of cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life. 3.Bearing structure of this type TCI tricone bits: High precision bearing with two thrust faces. Ball lock the cone. Hardfaced head bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved. 4.Seal and Lubrication of this type TCI tricone bits: Premium Oring, 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 . 5.Product Application this type TCI tricone bits: It can receive high WOB in the conventional drilling. It is suitable for various formations by matching cutting structure with different tooth shape, tooth density and tooth exposure height. 6.Advantage: 1. High-strength, high flexibility, high temperature and high wear resistance. 2. High-precision metal seal. 3. Locking roller ball, to adapt to high-speed. 4. The use of high strength high toughness carbide teeth, 5. Hours in the rotary cone bit with the impact, crushing and shearing the role of broken rock. 6. Cone bit to adapt to the soft, medium and hard of various strata. 7. Reasonable price and long working life.
