Oilfield Drilling Tool 17-1/2 Inch 6 Blades PDC Drill Bit
1 . Descriptions:
When selecting a PDC (Polycrystalline Diamond Compact) drill bit, it is crucial to evaluate the formation characteristics first. If the formation is hard, opting for a PDC drill bit is a wise choice as it can save costs and enhance cutter performance. However, for soft formations, alternative drill bit options should be considered. It's important to note that PDC drill bits generally have a higher price compared to other types like tricone or hammer bits due to their construction materials, which include tungsten carbide and diamond. Prior to choosing a PDC drill bit, it is essential to have a good understanding of its features and capabilities.
The performance of a PDC drill bit is influenced by several factors, including:
At our company, we prioritize adherence to API standards and offer a wide range of PDC drill bits that are extensively used in the drilling industry. Our selection includes PDC drill bits ranging in size from 3 to 22 inches, with 3 to 9 blades available. To cater to different budget requirements, we offer a diverse array of cutter options within various classifications.

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.
