Oilfield Dimond PDC Drill Bit 8-1/2 Inch Steel Body with 6 Blades
1 . Descriptions:
PDC drill bits are highly versatile tools that excel in various geological conditions, including soft rocks, hard rocks, and gravel formations. They find extensive application across diverse engineering projects, effectively meeting the specific requirements of each project.
Although PDC drill bits may come at a relatively higher price, their cost-effectiveness is exceptional. This is attributed to their efficient performance, extended lifespan, and outstanding drilling stability, which collectively yield significant economic benefits throughout drilling operations.
One of the notable advantages of PDC drill bits is their ability to provide adjustable blade density and shapes. This feature allows for precise drilling control and enables the achievement of desired drilling outcomes, even in complex formations that demand tailored drilling approaches.
Manufactured using premium blade materials and employing advanced processes, PDC drill bits undergo rigorous quality control procedures. This ensures consistent and reliable product performance, providing stability during drilling operations.
By combining versatility, cost-effectiveness, precision, and reliability, PDC drill bits stand as a cutting-edge solution that addresses the challenges posed by diverse geological conditions and meets the varying demands of engineering projects.

3 . PDC Bit profile
Profile shape is one of the most important characteristics of fixed-cutter bits, having direct influence on possibilities for cutter placement and densities and on hydraulic layouts. Profile also affects: Bit stability
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
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 Drill 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 drill Bit ; Becuase 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.
