Mill Tooth Tricone Bit 13-1/4 "API Three Cone Bits IADC 127 of Oil Mining Drilling Well

1 . Descriptions:

Steel Tooth (or Mill Tooth) bits are meticulously crafted in a variety of shapes and sizes, featuring an array of cutting structures and innovative features tailored to address the diverse challenges encountered in different downhole formations.

When it comes to soft rock formations, Mill Tooth tricone bits with steel teeth stand out as the preferred choice. These specialized bits are engineered to navigate through softer geological layers with precision and efficiency, ensuring optimal drilling performance in such conditions. The design of Mill Tooth tricone bits incorporates strategically spaced steel teeth that effectively prevent obstructions by maintaining wide gaps between the protruding teeth. This design feature plays a crucial role in preventing material blockages as the bit penetrates the top layer of the formation, allowing for smooth and uninterrupted drilling progress.

By leveraging the unique characteristics of Mill Tooth tricone bits, operators can confidently tackle drilling operations in soft rock formations with enhanced productivity and reliability. The durability and clog-resistant nature of these bits make them well-suited for applications where the risk of material buildup is a concern, ensuring continuous and efficient drilling performance throughout the operation.

4 . Bearing Types

There are primarily three types of bearing designs used in tricone drilling bits:

• STANDARD OPEN BEARING ROLLER BIT:

On these bits the cones will spin freely. This type of bit has a front row of ball bearings and a back row of roller bearings.

• SEALED BEARING ROLLERS BITS

These bits have an O-Ring seal with a grease reservoir for bearing cooling. The seals acts as a barrier against mud and cuttings to protect the bearings

• JOURNAL BEARING ROLLER BITS

These bits are strictly oil/grease cooled with nose bearings, O-Ring seal and a race for maximum performance.

5. Question :

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.

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.
