Bearing Structure

Nonsealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the probability of cone ropping to minimum.

Our aim is to supply the best quality products and the fastest and best service to meet every client's satisfaction. Many tricone bits for drilling is saled in web and tricone bit ebay, we are the tricone bit manufacturers and can compete with all of them,  Contact us when there is any inquiry or question or for best tricone bit cost Let's work together to bring your dream to reality. 


Feature and Advantage

1.Suit for drilling medium to medium-hard formations.

2.Asymmetrical blade cutter design and balanced bit load so that bit whirl is prevented.

3.Composite protection and low torque design improve rate of penetration.

Tricone bit is Widely used in borehole water well drilling, oil, gas well and mining projects. It mainly divided into steel tooth and TCI, diameter from 3 inch to 28 inch. 

Generally, steel tooth tricone bit mainly used for soft rock formation drilling, our steel tooth tricone bit IADC code includes 126,127,136,217,etc.TCI tricone bit is mainly used for hard rock drilling (rubber sealed bearing type) and very hard rock formation drilling (metal sealed bearing type).

tricone bits features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-ring provides adequate sealing for bearing durability. 


Application

1.Suit for drilling medium to medium-hard formations.

2.Asymmetrical blade cutter design and balanced bit load so that bit whirl is prevented.

3.Composite protection and low torque design improve rate of penetration.


Cations

1. Please select the applicable formation and parameters according to the instructions.

2. Carefully check the bits appearance and to check the bits threaded end face,whether the serial number on the box and certificate.

3. Selection of WOB and RPM should be within the limits of the recommended parameters, higher WOB and RPM cannot be used simultaneously.

4. Bottom hole must be clean and bit must not be used for long section reaming.

5. Drilling process must operate smoothly, find that there is Bie jump on abnormal phenomenon, should be timely analysis and take effective measures

6. The bit should be kept indoor with dry

7. and well ventilated conditions at 10-33℃ and kept from sunshine and rain. Stored under such conditions, quality of bit is guaranteed for 3 years.
