Hard Rock Drilling 8-1/4 inch 7 Blades PDC Bit of Diamond Drilling Tool
1 . Descriptions:
PDC, short for "Polycrystalline Diamond Compact," denotes the use of this advanced diamond material in creating drill bits, a development that has greatly enhanced the efficiency and durability of oil drilling tools.
One example is the S616 PDC bit, a fixed-head bit that rotates as a single unit, ensuring steady and reliable performance during drilling tasks.
Choosing a PDC bit involves considering factors like cutter density, size, bit profile, and blade type, all of which influence how well the bit performs in various drilling conditions and formations.
Our drill bits adhere to the API (American Petroleum Institute) standard, guaranteeing their compatibility and suitability for drilling operations. Available in sizes from 3 to 22 inches with 3 to 9 blades, our PDC drill bits offer a variety of cutter classifications to meet your specific needs and budget constraints.
2. Specification:
Unlike conventional drill bits featuring hardened metal teeth, PDC bits utilize industrial diamond cutters crafted from polycrystalline diamond materials. These cutters boast exceptional hardness and wear resistance, elevating the bit's cutting efficiency and durability across various drilling formations.
Engineered to endure high drilling forces and temperatures, the polycrystalline diamond compacts in PDC bits efficiently shear through encountered rock formations, facilitating swift drilling progress. These diamond cutters enhance stability, minimize vibrations, and ensure smoother, controlled drilling operations.
PDC bits have gained industry favor for their durability, superior cutting performance, and adaptability to diverse drilling conditions. The incorporation of industrial diamond cutters offers a notable edge, enabling operators to achieve accelerated drilling speeds and heightened overall efficiency.

3 . PDC Drill Bit profile
4 . Drill Bit PDC Cutters
At the core of a drill bit are Polycrystalline Diamond Composite (PDC) cutters, which directly engage with the rock, primarily using shearing action for removal. Within the demanding well environment, PDC cutters undergo frequent heating and cooling cycles, posing significant challenges.
PDC cutters with enhanced thermal stability and reduced thermal degradation tend to deliver superior performance, leading to higher Rates of Penetration (ROP) and improved wear resistance. Therefore, optimizing these cutters is crucial for maximizing efficiency.
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.
