Product Description
Rock Drilling Bit 17-1/2 Inch Steel Body Diamond PDC Drill Bit of API Spec
1 . PDC Drill Bit Descriptions:
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.
There are steel body and Matrix body PDC Bit . The two bit are the same just different on the material and manufacutre process Different .
The Steel body are used on the middle hard to hard formation, Then matrix body are used on the hard fromation to very hard formation .
Steel body advantage is : price is lower than matrix bdoy at the same condition . But steel body can improve the blades accounts to improve the cutter performance .
2. PDC Drill Bit 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 . PDC Drill Bit 'S 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 imp
