Oil PDC Bit 17-1/2 Inch Diamond Drilling Tool Of API Spec
1 . Descriptions:
PDC drill bits are efficient tools used for rock drilling. With a compact external structure typically composed of multiple polycrystalline diamond compact (PDC) cutters, they exhibit high hardness and wear resistance. Widely employed in areas like oil drilling and geological exploration, PDC drill bits enable rapid and precise drilling through various geological formations. Renowned for their excellent performance, they boast high efficiency, strong stability, and long service life, excelling in complex geological conditions. PDC drill bits are indispensable tools in modern drilling applications
PDC bits are specifically engineered for high-speed drilling in shale, limestone, and sandstone formations. Diverging from roller cones, these polycrystalline diamond compact (PDC) drill bits are solid bodies without any movable components. The fixed-cutters efficiently scrape away the rock, enabling more efficient operation at higher rotation speeds, particularly in consolidated formations.
2. Specification:
Polycrystalline diamond compacts PDC bit in the Oil and Gas Industry PDC bits get their name from the polycrystalline diamond compacts used for their cutting structure. A PDC bit is a drill bit fitted with industrial diamond cutters instead of hardened metal teeth.

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 imp
