Answer any question about the products for you.

In the world’s first -class ranks, the product size range covers 3 1/2 ~ 36 inches of each size section, forming more than 1,400 specifications of 11 conventional series and six functional products series, which can meet the soft stratum to extremely hard strata. Drilling projects need to maintain competitive advantages in the market for a long time.

Kingdream Tricone Bit Cutting Structure

This product line may have either steel teeth or TCI. To increase bit life, steel teeth are hardfaced with wear-resistant tungsten carbide based material. Depending on the rock hardness, either sides surfaces or side and end surfaces of steel are hardfaced.

The gauge may be protected with tungsten carbide inserts. For additional protection against gauge loss,a near gauge of tungsten carbide insert may be used.

Kingdream tricone drill bit Gauge Structure

The multiple heel position with gauge trimmer on the heel, tungsten carbide and hardfacing on the shirttail, strengthened spear point will enhance the gauge protection.

Kingdream Tricone Bit TCI Bearing Structure

High precision journal bearing with two thrust faces. Ball locked 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, and suitable for high rotary speed.

Kingdream Tricone Bit TCI Seal

The bearing seal is adapting the high quality HNBR O-ring. The best seal compression and the radial seal structure can enhance the seal performance. The compensation system and the high quality bit grease can limit pressure differential, and greatly increase the lubricating reliability.


Bit lubrication system is designed to compensate grease consumption and pressure during long-term operation. It consists of a grease reservoir with a rigidly mounted cap, a flexible diaphram, a metal canister protecting the diaphram from breakage, and channels to connect the grease reservoir with friction area in bearing.

Kingdream Tricone Bit TCI Application

Very soft formation with low compressive formations, such as clay/gypsum/salt/soft shale/soft limestone.etc

We supply different size of this type of tricone bit for drilling as clients’ requirement.


How to chosse the right tricone bit for yourself?

Soft formation TCI tricone bits:

The soft formation TCI tricone bits are used for low compressive strength, very soft formations. This bit maximized to 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.

Medium formation TCI tricone bits:

The medium formation TCI tricone bits 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 for mations. The HSN rubber O-ring provides adequate sealing for bearing durability.

Hard formation TCI tricone bits:

The hard formation TCI tricone bits can be used for hard and abrasive formations. Wear resistance 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.
