Hard Rock Drilling 9-1/2 Inch PDC Bit of Diamond Drilling Tool
1 . Descriptions:
Diamond PDC bits are crafted using advanced "Polycrystalline Diamond Compact" technology. These cutting-edge bits revolutionize efficiency and durability in oil drilling operations.
Take, for instance, the S616 PDC drilling bit, a fixed-head tool designed to rotate seamlessly as a single unit, guaranteeing unwavering and dependable performance throughout drilling processes.
When considering a PDC drill bit, crucial factors like cutter density, size, bit profile, and blade type play pivotal roles in performance across various drilling conditions.
Our range of PDC bits adheres to API standards, ensuring seamless compatibility with drilling operations. Available in sizes ranging from 3 to 22 inches and equipped with 3 to 9 blades, these bits feature diverse cutter classifications to cater to specific needs and budget constraints
2. Specification:
PDC bits like the S616 or M616 feature a 6-blade steel or matrix body with a 16mm main cutter. The IADC code specifies the bit's compatibility with hard, soft, or specific profile formations, offering valuable information.
Therefore, the IADC 323 code signifies distinct characteristics of the PDC drill bit.

4 . Drill Bit PDC Cutters
At the heart of a drill bit are polycrystalline diamond composite (PDC) cutters, which engage directly with the rock, using primarily shearing action for removal. In the demanding environment of a well, PDC cutters undergo frequent heating and cooling cycles, which pose significant challenges.
PDC cutters with improved thermal stability and reduced thermal degradation tend to perform better, resulting in higher rates of penetration (ROP) and improved wear resistance. Optimising these cutters is therefore critical to maximising effiency.
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.
