PDC Fixed Cutter Bits 8 Inch Diamond Drilling Tool Of API Oilfield
1 . Descriptions:
PDC drill bits are a significant innovation in drilling tools, utilizing polycrystalline diamond materials to create polycrystalline diamond compact (PDC) bits, which are among the most important material advancements in recent years. These bits feature a fixed-head design, rotating as a single unit without independently moving parts.Our PDC drill bits have gained widespread recognition in the drilling industry due to their adherence to API standards and exceptional performance. Designed to meet the diverse needs of drilling operations, our product range includes PDC drill bits in a wide range of sizes, from 3 to 22 inches. This ensures that our customers can find the perfect fit for their specific drilling requirements.
To further enhance versatility, our PDC drill bits are available with options for 3 to 9 blades. This allows operators to customize the cutting structure according to the desired drilling parameters, formation characteristics, and efficiency goals. The number of blades directly affects the cutting efficiency and durability of the drill bit, offering flexibility to optimize performance in various drilling conditions.

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.
