PDC Bit 8-1/2 Inch 5blades Diamond Drilling Tools Of API Spec
1 . Descriptions:
What does PDC mean in drilling? Polycrystalline diamond materials, for use in polycrystalline diamond compact (PDC) bits, are one of the most important material advances for oil drilling tools in recent years. Fixed-head bits rotate as one piece and contain no separately moving parts.
All of our Drill bits are fit for API standard and used in the drilling Industry. The PDC drill bits size 3~22inch with 3~9Blades are available. And different classification cutter are optional according to your budget .
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.

3 . PDC Drill Bit profile
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 import
