PDC Hard Rock Drill Bit 8 Inch Diamond Drilling Tool Of HDD Drilling Bit

1 . Descriptions:

Fixed cutter bits differ from traditional roller cone bits in that they have no moving parts. Instead, the cutting structures and bit body rotate as a single unit. This design ensures high stability and consistency, resulting in increased drilling efficiency and accuracy.

The main types of fixed cutter bits include PDC (polycrystalline diamond compact), TSP (thermally stable PDC), and diamond bits. PDC bits consist of multiple small diamond particles held together by a metal binder under high pressure and temperature. TSP bits offer higher thermal stability, allowing them to maintain cutting performance in high-temperature environments. Diamond bits use natural or synthetic diamonds as the cutting structure, providing excellent hardness and wear resistance.

4 . Drill Bit PDC Cutters

Polycrystalline Diamond Composite (PDC) cutters are the main point of contact for a drill bit. PDC bits remove the rock mainly by shearing.

The PDC cutters are exposed to a lot of heating and cooling down the well, a very challenging environment.

PDC cutters that have lower thermal degradation and more thermal stability generally achieve higher ROP and increased wear resistance. So, optimizing the cutter is important.

5. Drill Bit Nozzles

Drill bit nozzles help clear the cutting area and cool the Polycrystalline Diamond Composite (PDC) cutters.

Effective placement of these nozzles along with the angle they are set at plays a critical role on how efficient the drill bit performs.

Fluid channels also complement nozzle placement to improve the clearing of cuttings.

6. Steel Body PDC Bits

Steel body is the opposite of matrix body. It can of withstanding high impact loads, but is softer and lacks protective features. The strength and ductility of steel give steel-bit bodies high impact resistance.

Steel bodies are considerably stronger than matrix bodies.

A beneficial feature of steel bits is that they can easily be rebuilt a number of times because worn or damaged cutters can be replaced rather easily. This is a particular advantage for operators in low-cost drilling environments.

Polycrystalline diamond compact (PDC) drill bits are different than roller cones in that they are one piece bodies with no moving parts. The fixed-cutters shred the rock, so the bit is able to operate with higher rotation speeds more efficiently in consolidated formations.

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.
