114-117
Soft Formation Tooth Bits
The 114-117 bits are used to drill low-compressive strength, soft formation. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hard facing is used to control tooth wear. On the softest bits type this hard facing completely covers the bit teeth.

127
Medium-Hard Formation Tooth Bits
The 127 bits are used to drill high-compressive strength, medium hard formations. Short projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear.

437
Soft Formation TCI Tricone Bits
The 437 TCI bits are used to drill low compressive strength, very soft formations. 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, result in high bit penetratione rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations.

517
Medium Formation TCI Tricone Bits
The 517 features aggressive chisel tungsten carbide insert on the heel rows and inter rows. This design provides a fast drilling rate and added cutting strcture durability in medium-to-medium hard for-mationes. The HSN rubber O-ring provides adequate sealing for bearing durability.

637
Hard Formation TCI Tricone Bits
The 637 bits can be used to drill hard and abrasive forma-tions. Wear-resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical-durability and long life.

617
Medium-Hard Formation TCI Tricone Bits
The 617 feature robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fest drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-rin provides adequate sealing for bearing durability.

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.

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.
