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.
Steel tooth bits series: Soft formation tooth bits: The soft formations tooth bits are used to drill low compressive strength, soft formations. Long projection tooth lengths are used on high offset cones to provide the greatest penetrations rates possible. Wear resistance hard facing is used to control tooth wear. On the softest bit types this hard facing completely covers the bit teeth. Medium hard formations tooth bits: The medium hard formation tooth bits are used to drill high compressive strength, medium hard formations. Shoot projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear.

1.The use of new surface wear-resistant materials, more effective use of positive and negative ions to prevent mud package more effectively. 2. Optimize the structure design, increase the narrow area in the design of the drill bit, deepen the channel, improve the thickness of the blade reasonably, so as to increase the flow passage area in the use of the drill bit in the maximum range, and improve the chip removal ability of the drill bit. 3. Using bottom-hole simulation and nozzle optimization design, the number and position of nozzles are reasonably arranged, which can prevent mud bag more effectively. 4.We also have other high quality drill bit products. 5.If you wann it please contact me.
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 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 . 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.
