Oil Diamond Drilling Tool 17inch PDC Drill Bit of Down Hole Directly
1 . Descriptions:
Selecting the appropriate drill bit is of utmost importance when it comes to achieving successful drilling outcomes. The decision between a PDC drill bit and a fixed drill bit should be carefully considered.
The International Association of Drilling Contractors (IADC) has established a classification system based on four key characteristics that determine the suitability of fixed-cutter bits:
- PDC Drill Bit Body Material
- Density of the PDC Drill Bit Cutter
- Size or Type of the PDC Drill Bit Cutter
- Profile of the PDC Drill Bit
At our company, we prioritize adherence to API standards and offer PDC drill bits that are widely utilized in the drilling industry. Our range of PDC drill bits encompasses sizes from 3 to 22 inches, featuring 3 to 9 blades. To cater to various budgetary requirements, we provide a diverse selection of cutter options within different classifications.
By considering these factors, you can make an informed decision and choose the most suitable drill bit for your drilling needs.

4 . PDC Drill Bit Cutters
Polycrystalline Diamond Composite (PDC) cutters of PDC drill Bit 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 and manufacutre process
Steel body of PDC Drill Bit is the opposite of matrix body of PDC Drill Bit . 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.
