Diamond 4-1/2" PDC Drill Bit of Oil Drilling Tool
1. Descriptions of PDC Drill Bit
PDC bit is a fixed cutter drilling tool with polycrystalline
diamond compact cutters used for rock drilling in oil, mining,
water or gas wells. This drilling tool is manufactured according to
API specifications and is API certified. The PDC cutters are made
of synthetic diamond material, which is the hardest known material,
making it extremely wear-resistant. Compared to tricone bits, PDC
bits generally offer higher drilling efficiency but at a higher
cost.
PDC bits utilize multiple diamond cutters arranged in specific
patterns to shear the rock formation. These bits are mainly
categorized into two types: matrix body PDC bits and steel body PDC
bits, designed for different drilling conditions. Matrix body PDC
bits are typically used in more abrasive formations, while steel
body PDC bits are often employed in softer formations.
2. Specification:
PDC bits such as the S616 or M616 are specified with a 6-blade
steel or matrix body and a 16mm main cutter. The IADC code
indicates whether the bit is suitable for hard, soft or specific
profile formations, providing additional insight.
So the IADC 323 have different mean of the PDC drill bit.

4 . Drill Bit PDC Cutters
At the heart of a drill bit are polycrystalline diamond composite
(PDC) cutters, which engage directly with the rock, using primarily
shearing action for removal. In the demanding environment of a
well, PDC cutters undergo frequent heating and cooling cycles,
which pose significant challenges.
PDC cutters with improved thermal stability and reduced thermal
degradation tend to perform better, resulting in higher rates of
penetration (ROP) and improved wear resistance. Optimising these
cutters is therefore critical to maximising effiency.
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.PDC Drill Bit Optional Feature :
There are much more feature of the PDC drill bit for choose ,which
is increase the PDC bit stablility ,wear resistance and rear
,cutter performance and
7. Steel Body PDC Bits
Steel body of PDC 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.
