Rock Diamond Drilling OFf Hard Formation 8.5inch PDC Drill Bit
1 . Descriptions:
Diamond PDC bit is the harness the power of "Polycrystalline Diamond Compact" (PDC) technology. This advanced diamond material revolutionizes the efficiency and longevity of drill bits in oil drilling operations.
The S616 PDC drilling bit exemplifies excellence as a fixed-head tool that operates seamlessly as a unified entity, guaranteeing unwavering and dependable performance throughout drilling endeavors.
In the selection of a PDC drill bit, key considerations such as cutter density, size, bit profile, and blade type are pivotal factors that influence performance across diverse drilling conditions.
Our range of PDC bits adheres rigorously to API standards, ensuring seamless compatibility with drilling operations. These bits are available in sizes ranging from 3 to 22 inches with 3 to 9 blades, offering various cutter classifications tailored to specific needs and budgets.
2. Specification:
PDC bits such as the S616 or M616 are specified with a 6-blade steel or matrix body and a 16mm main cutter. The IADC code indicates whether the bit is suitable for hard, soft or specific profile formations, providing additional insight.
So the IADC 323 have different mean 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.
