About the product

TCI tricone bits for Mining and Rock Drilling

The strength and wear resistance of inserts are improve by using carbide inserts with high strength and high wear resistance.

Surface of the high precision bearing heat treated by using advanced heat treatment process to improve the load capacity and service life of the bearing.

The service life of the bearing is further extended by adopting harder and mort wear resistant material for thrust bearing.

Preventing reflux structure has dual function, it can avoid air counterflow and dust entering into bearing when the air-compressor stop working accidentally, and separate air and water in order to avoid water entering into bearing when it works normally to prolong the life of bearing.

Structural features:

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 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.

Advantage

1.High-strength, high flexibility, high temperature, high wear resistance.

2. High-precision metal seal.

3. Locking roller ball, to adapt to high-speed.

4. The use of high strength high toughness carbide teeth,

5. Hours in the rotary cone bit with the impact, crushing and shearing the role of broken rock.

6. Cone bit to adapt to the soft, medium and hard of various strata.
