Diamond Drilling 9-1/2Inch PDC Drill Bit of Oilfield Rock Drilling
1 . Descriptions:
What is the meaning of PDC in drilling tools? Polycrystalline diamond materials have emerged as a significant technological advancement in oil drilling tools. These materials are used in the construction of polycrystalline diamond compact (PDC) bits. Fixed-head bits, which rotate as a single unit without any independently moving parts, are employed.
Factors such as cutter density, cutter size or type, bit profile, and cutter blades contribute to the performance of our drill bits. All of our drill bits comply with API standards and are widely utilized in the drilling industry. Our PDC drill bits are available in sizes ranging from 3 to 22 inches, with 3 to 9 blades. Additionally, we offer various cutter classifications to accommodate different budgetary requirements.
2. 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 . 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.
