Rock Drilling Bit Manufacture 12-1/4 Inch PDC Drilling Bit Of API Rock Bit
1 . Descriptions:
PDC (Polycrystalline Diamond Compact) drill bit is used for cutting the rock of underground . There are different formation will be used different type of drill bit . The hard rock will used the special manufacture drill bit . It should be design by the professional person after getting the formation constructer .
Its design is purposefully customized to deliver superior performance and an extended lifespan in challenging drilling operations.
The PDC Drill Bit's unique blend of exceptional resilience, state-of-the-art cutting structure, efficient hydraulics, and prolonged lifespan render it an essential instrument for overcoming the most formidable drilling obstacles in the oil and geological sectors.

4 . Drill Bit PDC 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. Drill Bit 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.
