PDC Fixed Cutter Bits 8 Inch Diamond Drilling Tool Of API Oilfield
1 . Descriptions:
PDC drill bits are a significant innovation in drilling tools,
utilizing polycrystalline diamond materials to create
polycrystalline diamond compact (PDC) bits, which are among the
most important material advancements in recent years. These bits
feature a fixed-head design, rotating as a single unit without
independently moving parts.Our PDC drill bits have gained
widespread recognition in the drilling industry due to their
adherence to API standards and exceptional performance. Designed to
meet the diverse needs of drilling operations, our product range
includes PDC drill bits in a wide range of sizes, from 3 to 22
inches. This ensures that our customers can find the perfect fit
for their specific drilling requirements.
To further enhance versatility, our PDC drill bits are available
with options for 3 to 9 blades. This allows operators to customize
the cutting structure according to the desired drilling parameters,
formation characteristics, and efficiency goals. The number of
blades directly affects the cutting efficiency and durability of
the drill bit, offering flexibility to optimize performance in
various drilling conditions.

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.
