Roller Cone Drill Bit 8-1/2 Inch TCI Drilling Tool IADC 435

Description :

• Roller cone bits have rollers rotating around bearings. Roller cone bits use steel teeth or tungsten carbide inserts as cutting elements.
• A roller cone bit removes rock by crushing, gouging and scraping.
• Roller cone bits are made up of three legs welded together.
• Each leg holds a rolling cone fitted with teeth or inserts. Teeth are milled directly in the cone where tungsten carbide inserts are pushed in holes that are drilled in the cone.
• Roller cones that have teeth milled into them are called tooth bits. These steel teeth are brazed over with a protective hard facing which substantially increases the life of the bit. Steel tooth bits are mainly used for fast soft rock applications like surface bits or shallow wells. When the cutters are made from tungsten carbide inserts, the bit is called a TCI (tungsten carbide insert) bit. TCI bits are more durable but are not as aggressive as a steel tooth bit. TCIs are used in harder more abrasive applications.

Specification :

Tricone Bit Size : 8-1/2”
IADC : 435
Make Up Torque(KN.M): 24.1-26.5
API Connect : 4-1/2” REG
Weight on Bit (KN): 108-227

APPLICATION
Petroleum & gas, water well, mining and tectonic industries, oil field, construction,
geothermal, directional boring, and underground foundation work.

RE: Medium hard formation /high compressive strength

Tricone Bit Cutting Structure
Unique steel tooth structure effectively improving the wearing resistance of the
teeth and greatly increasing the rate of penetration.

Tricone Bit Gauge Structure
Enhanced gauge protection with hard facing on the shirttail, strength enabled
with special insert tungsten carbide.

Tricone Bit Bearing Structure
High precision journal bearing, hard-faced bearing surface. Cone bearing inlaid
with friction-reducing alloy and then silver-plated, made the rotating more
stable, safe, and durable.

Tricone Bit Seal and Lubrication
The patented unique metal seal can enhance the seal performance, it has longer
durability than the rubber seal. The compensation bearing grease system greatly
increases the lubricating reliability and improve the bearing life effectively.

Application:
Soft formations with low compressive strength,such as shale/clay/ sand stone/
soft limestone/ halite/anhydrite.etc.

We supply different sizes of this type of bit as clients’requirement.

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.
