Tungsten Carbide Bit 8 -1/2"Tri Cone Roller Cone Bit Of Mining Drilling Ring Tool

1 . Descriptions:

Tungsten Carbide Insert (TCI) bits are are used middle to hard rock formation which offers a variety of carbide inserts such as spherically shaped inserts for very hard rock or conically shaped inserts for softer rock. The number of rows of inserts is directly related to the type of application and the size of hole to be drilled. here are also open and sealed bearings available as well as three types of shirttail protection to choose from. TCI stands for Tungsten Carbide Insert.

2. Tricone Specification:

3 . Roller Cone Bit Profile

The Tricone Bit is composed by Tricone bits consist of three rotating cones that have teeth made of a hard material, usually steel, tungsten carbide, or diamond.

These teeth crush the rock as the cones rotate, and the rock debris is then cleared away by the drilling fluid

4. What we should be pay attention on choosing the tricone drill bit ?

• IADC code passport
• TCI & Steel tooth options
• Additional tungsten carbide inserts on heel rows
• Tungsten carbide coating on cone bodies
• Diamond coated tungsten carbide inserts on the gauge of the cones
• Tungsten carbide inserts on the shirttail of the legs
• Additional central nozzle for cleaning cones

The tricone feature is that they come with their own passport as below :

• The specification of the cones
• The quality stamp signed by the person who made and checked the bit
• The recommended drilling parameters to get the best performance out of the bit:
• Bit weight
• Rotation speed
• Flushing volume

Which type of tricone you should choose ?

It depends on the geology you are drilling in and the diameters of the borehole you are drilling. The International Association of Drilling Contractors (IADC) have developed an easy use step system to choose the right tricone for your geology with additional features such as bit protection for longer production life.

5. Roller Cone Application Area

Suzhou Energy Tool Co., Ltd . (short for “ENG ” ) is a high-tech company formed by a group of drill bit experts with over 20 years of work experience in the world's top oil service companies. ENG has cooperated with many research institutes at home and has formed an advanced technological system based on market-oriented and continuously promoting technological innovation and product improvement. ENG‘S bits production lines are equipped with 5-axis machining centers, Modern lathes, and FMS (Flexible manufacturing system ) and can produce matrix body and steel body PDC bits from 3-1/4” to 26” in diameter.

ENG has been keeping on  producing high-quality products to meet the buyer diffferent requirement of different drilling well and rock fromation . The company’s QMS has been award  API, ISO 9001 certification for many years. ENG has Obtained  21 patents by Chinese government .On the products Research and Development, ENG has built the basis of 3-dimensional CAD and PDM (Product Data Management ), can technically control the whole process of product manager, so that the product development can be done in a fast and precise manner to maximally meet the time and function requirement of the market for product lifecycle management.

ENG developed different performance series PDC cutters for PDC bit to meet different drilling applications and drilling requirements of different formations. Some PDC Cutter is imported from the USA Or Europe. ENG's advantage is high product quality, short delivery time, small lot, and multi-types. The products have been exported to over 10 countries Such as the USA, Australia, Indonesia, Thailand, Malaysia, Indonesia, Argentina, and so on.
