Roller Cone Rotary Tools Rock Drill Bit for Oil Well


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


2.Gauge structure this type TCI tricone bits:

Multiple gaugeprotection 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 frictionreducing alloy and then silverplated. 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.

Under drilling and pressure effect, drilled goods as the cement is sucked at the bottom, through the rotation, the part of sucked is cutting in the direction of circumference, it will be drilling down gradually. Side lobe will be milled by drilling goods, forming cylinder space so that better dressing the well bore by drilling.
