Diamond PDC Bit 4-1/2 " Rock Drilling Bit Of Oilfield Hard Formation
1 . Descriptions:
PDC stands for "Polycrystalline Diamond Compact." In the context of drilling tools, PDC refers to the use of polycrystalline diamond materials in the construction of drill bits. This material advancement has been significant in recent years, offering improved performance and durability for oil drilling tools.
The S616 PDC bit is a fixed-head bit, which means it rotates as a single piece and does not contain separately moving parts. This design ensures stability and reliability during drilling operations.
When selecting a PDC bit, several factors come into play, including cutter density, cutter size or type, bit profile, and cutter blades. These factors contribute to the performance and efficiency of the drill bit in different drilling conditions and formations.
All our drill bits conform to the API (American Petroleum Institute) standard, ensuring their compatibility and suitability for use in the drilling industry. The PDC drill bits we offer come in sizes ranging from 3 to 22 inches, with options of 3 to 9 blades. Additionally, we provide different classification options for the cutters, allowing you to choose based on your specific requirements and budget.
2. Specification:
Unlike traditional drill bits with hardened metal teeth, PDC bits are equipped with industrial diamond cutters. These cutters are made from polycrystalline diamond materials, which offer exceptional hardness and wear resistance. The use of diamond cutters enhances the cutting efficiency and durability of the bit, allowing it to efficiently penetrate various formations encountered during drilling.
The polycrystalline diamond compacts in PDC bits are engineered to withstand high drilling forces and temperatures. They effectively shear through the rock formations encountered, resulting in efficient drilling progress. The diamond cutters also provide improved stability and reduced vibrations during drilling, contributing to smoother and more controlled operations.
PDC bits have become a preferred choice in the industry due to their durability, enhanced cutting performance, and the ability to handle a wide range of drilling conditions. The use of industrial diamond cutters provides a significant advantage, allowing operators to achieve higher drilling speeds and increased overall efficiency..

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. PDC Drill Bit Nozzles
PDC 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 of PDC Bit 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.
