Product Description
API Diamond Rock Bit 17-1/2 Inch 6 Blades API PDC Rock Bit
1 . Descriptions:
Engineered for the most demanding environments, our 17-1/2" 7-blade PDC bit is the ultimate solution for aggressive drilling in hard and abrasive formations. Featuring a sophisticated triple-cutter row (3 cutter row) design, this oil drill bit provides unparalleled redundancy and impact resistance, ensuring maximum footage and reduced ROP (Rate of Penetration) fluctuations in deep-well applications. The heavy-duty 7-blade geometry offers superior borehole stability and efficient cuttings removal, minimizing torque-on-bit while maintaining directional control. .

4 . PDC 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. PDC 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 of PDC Drill Bit . 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.
