1.Cutter Structure The durability of premiun Tungsten carbide inserts is improved with new formulas and new techniques 2.Gauge Structure Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inders and hardfacing on the shirttail increases gauge holding capacity and bearing life. 3.Bearing Structure High Precision jourmal bearing with two thrust faces. Balls lock the cone. hardfaced head bearing surface. cone bearing inlaid with friction-reduceing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved,and suitable for high rotary speed. 4.Seal and Lubracation Advance metal face seal lowers seal frictional force and overall seal torque and improves seal life. the pressure compensator syste, and advanced grease can greatly increas the lubracating relaibility. 5.Six-Point Position stabilzation Structure The bit leg is designed with specific interated stability structure, which provides near six-point contact with borehole wall for the bie. this new feature gives the bit unequaled stability which greatly reduces bit vibration protects the cutting structure from damageding blows and keeps good borehole quality, the thickened nozzle wall can protecy hydraulic system from wear and fluid erosion. 6. Product Application It is suitable for downhole motor and high speed applications, and is the ideal selection for drilling directional and horizontal wells.

1.This type of bits are used in low press resistance soft to medium formation, shales, clay, salt, etc., it can work in a high rpm and low wob with fast drilling speed. 2. Surface of cones and teeth are hard enhanced to extend the working life of bit. 3. Teeth distributed optimal design largely improve the working efficiency of breaking down s

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.
