Diamond PDC Bit 9-1/2 Inch Rock Drilling Bit Of API Spec
1 . Descriptions:
The PDC stands for Polycrystalline Diamond Compact, which plays a significant role in the realm of Diamond drilling tools. Polycrystalline diamond materials have revolutionized the technology used in oil drilling tools, particularly in the construction of PDC bits. These bits, known as fixed-head bits, rotate as a single unit without any independently moving parts.
To ensure optimal performance, several factors come into play when considering PDC drill bits. These include PDC cutter density, PDC cutter size or type, PDC bit profile, and the number of PDC cutter blades. Rest assured, all our PDC drill bits comply with the rigorous API standards and are widely embraced by the drilling industry. Our range of PDC drill bits spans from 3 to 22 inches in size, equipped with 3 to 9 blades.
Additionally, we offer a variety of cutter classifications to cater to diverse budgetary requirements .
2. PDC Bit Specification:
Polycrystalline diamond compacts PDC bit in the Oil and Gas Industry PDC bits get their name from the polycrystalline diamond compacts used for their cutting structure. A PDC bit is a drill bit fitted with industrial diamond cutters instead of hardened metal teeth.

4 . PDC Drill Bit'S 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 'S 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.
