Product Description
Diamond Rock Drilling 12-1/4 Inch PDC Drill Bit of API Spec
1 . Descriptions:
PDC drill bits prove to be versatile and well-suited for a range of geological conditions, including soft rocks, hard rocks, and gravel formations. Their broad applicability makes them a preferred choice for various engineering projects, effectively meeting specific project requirements.
While PDC drill bits may come with a relatively higher price tag, their cost-effectiveness is remarkable. This is due to their efficient performance, extended lifespan, and exceptional drilling stability, which collectively contribute to significant economic benefits during drilling operations.
One of the key advantages of PDC drill bits is their ability to offer adjustable blade density and shapes. This flexibility allows for precise drilling control and the achievement of desired drilling outcomes, even in complex formations that demand specific drilling approaches.

4 . PDC Drill Bit 'S Cutters
Polycrystalline Diamond Composite (PDC) cutters are the main point of contact for a drill bit. PDC bits remove the rock mainly by shearing.
The PDC cutters are exposed to a lot of heating and cooling down the well, a very challenging environment.
PDC cutters that have lower thermal degradation and more thermal stability generally achieve higher ROP and increased wear resistance. So, optimizing the cutter is important.
5. PDC Drill Bit'S Nozzles
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 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.
