Bit profile.

Drill Bit PDC Cutters
Cutters made of Polycrystalline Diamond Composite (PDC) are a drill bit's primary point of contact. PDC bits primarily chop the rock out of the way.
The PDC cutters operate in a highly difficult environment with frequent heating and cooling of the well.
PDC cutters with greater thermal stability and less thermal deterioration typically have higher ROP and stronger wear resistance. Therefore, the cutter needs to be optimized.

Drill Bit Nozzles
The Polycrystalline Diamond Composite (PDC) cutters are kept cold and the cutting zone is cleared by drill bit nozzles.
The positioning of these nozzles and the angle at which they are set have a significant impact on how effectively the drill bit operates.
Additionally, fluid channels work in conjunction with nozzle location to enhance cuttings removal.


Steel Body PDC Bits
The antithesis of a matrix body is a steel body. Although it is softer and lacking protective features, it is capable of withstanding severe impact loads. Steel bit bodies provide a high level of impact resistance due to the strength and ductility of steel.
Matrix bodies are significantly weaker than steel bodies.
Steel bits have the advantage of being easily rebuilt multiple times due to the ease with which worn or damaged cutters can be swapped out. Operators who operate in low-cost drilling environments will particularly benefit from this.
In contrast to roller cones, polycrystalline diamond compact (PDC) drill bits have a single, non-moving body. In consolidated formations, the bit can operate at faster rotation rates because the fixed-cutters efficiently shred the rock.

Why choose PDC Drill Bit
PDC has been used with great success in the oil field, and has recently become a go-to technology for many drillers in the Waterwell and HDD industry.
PDC bits have the fixed blades with large, hard, abrasion-resistant cutters manufactured from a boned mass of microcrystalline synthetic diamonds and designed to excavate hole by shearing the formation while tricone insert bit works by crushing it.

Softer the formation and homogenous smaller the number of blades and bigger the size of the PDC cutters.
