Hard Rock Diamond PDC Drilling Bit 9-1/2 " of API Spec Drilling Tool
1 . Descriptions:
PDC, short for Polycrystalline Diamond Compact, represents the use of advanced diamond material in the manufacture of drill bits that significantly improve the efficiency and durability of oil drilling.
One example is the S616 PDC bit, a fixed-head tool that rotates as a single unit to ensure consistent and reliable performance during drilling.
When selecting a PDC bit, factors such as cutter density, size, bit profile and blade type influence its effectiveness in different drilling conditions.
Our PDC bits meet API standards, ensuring compatibility for drilling operations. Available in sizes from 3 to 22 inches with 3 to 9 blades, they offer different cutter classifications to suit 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.

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 efficiency.
5. PDC Drill Bit Nozzles
PDC drill bit nozzles help to clear the cutting area and cool the polycrystalline diamond (PDC) cutters.
Effective placement of these nozzles, along with the angle at which they are set, plays a critical role in the performance of the drill bit.
Fluid channels also complement nozzle placement to improve cuttings removal.
6. Steel Body PDC Bits
The steel body of the PDC bit is the opposite of the matrix body. It can withstand 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 much stronger than matrix bodies.
An advantage of steel bits is that they can easily be rebuilt a number of times, as worn or damaged cutting edges can be replaced relatively easily. This is a particular advantage for operators in low-cost drilling environments.
Polycrystalline diamond compact (PDC) bits differ from roller cones in that they are one-piece bodies with no moving parts. The fixed cutters crush the rock, allowing the bit to operate more efficiently at higher speeds in consolidated formations.
