Kingdream 22 Inch IADC 617 Tci Tricone Drill Bit

Our Tricone drilling bits are designed with three cone-shaped rotating heads that work together to provide optimal drilling performance. Each head has rows of hardened steel teeth that bite into the rock, making it easier to break apart and remove. The teeth are arranged in a pattern that allows for smooth and efficient drilling, even through tough rock formations. Our Tricone drilling bits come in a range of sizes and designs to meet the specific needs of different drilling projects.


Our Tricone drilling bits are designed for use in a variety of drilling applications, including oil and gas exploration, mining, construction, and water well drilling. With their unique three-cone design, they are able to drill through a wide range of rock formations, from soft sedimentary rocks to hard, crystalline formations. The hardened steel teeth on each cone are designed to withstand the high temperatures and pressures of drilling, ensuring that the bit can continue to operate effectively even under challenging conditions.

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 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 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.
