Tricone Rock Bit

Product details:

Kingdrilling supply you heavy tricone rock drill bits to meet any of your requirement about rock drilling. We can classified this kind of bit according to their diameter, API number and IADC number. The IADC number can help us to further classify the tricone bits according to the tooth material of construction, suitability for drilling into soft, medium or hard rock and bearing type used. Kingdrilling can supply all of the possible IADC number combinations.


Product feature:

1.The service life of the bearing is further extended by adopting harder and more wear resistant material for thrust bearing.
2.This series oil well rock bit use sealed roller bearing structure. With rollers arranged in grooves recessed in the cone body, the size of the bearing journal is increased.
3.Thrust bearing surfaces are hard faced and treated with friction reducing technology.

How to order:

Bit(s) Dimension + IADC code(s) + Pin Thread Size(s)

As well as the following information please:

1. Expected rock bit parameters required;

2. Drill rig and compressor information;

3. Rock formation condition;

4. Rock bits performance statistics.

 

FAQ:

1. How about the common packing?

A: If there is no special packing demand, we will take it as our normal packing. First in small carton, and then put in the bigger carton together to make sure goods completed.

2. How to control quality?

A: We have our own experienced QC team,there will be strict inspection and testing for each order before shipping out.

 

3.What is the general delivery time?

15 working days for DTH bits.

20-25 working days for DTH hammer

3-5 working days for ex stock items.

 

4. Competitive price:

A: KINGDRILLING factory can supply you the lowest price due to direct sale to customers without distributor!

 

5. Methods of Payment:

T/T (Telegraphic Transfer) or Western Union.

 

6. How to choose the suitable Pneumatic DTH hammer?

a. Hole Size:

It is better for you to choose the one which the outside diameter is nearest to the hole diameter. This will reduce the hole collapse, and the hole cleaning is easier.

b. Air Consumption:

You must consider about the consumption of compressed air when you use the Pneumatic DTH hammer. Generally speaking, with the raising of the size of hammer, peak performance requires higher compressed gas consumption and lower pressure. In order to make sure each hammer will be used in the proper consumption of compressed air and pressure, please refer to the attachment.

c. Drill rig Capacity:

The larger bit and hammer will need the drilling rig to provide greater torque and promoting force, but do not exceed the maximum load of the drill. As for the other questions about drill ability, please consult your sales representative
