Product Description
API Rock Bit 13.5 Inch 9 Nozzles Pdc Cutter Bit of Rock Drilling Tools
1 . Descriptions:
According to the International Association of Drilling Contractors (IADC), the Fixed-cutter bit classification composed of four characters that designate:
- Body material.
- Cutter density.
- Cutter size or type.
- Bit profile
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 .

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.
PDC Cutters are made from tungsten carbide substrate and synthetic diamond grit. The diamond and carbide substrate grow together through chemical bonds under high temperature and high-pressure conditions.
The most two important materials of PDC cutters are diamond grit and carbide substrate.
5. Drill Bit Nozzles
The cemented carbide nozzle is a key component for the diamond drill bit. The tungsten carbide drill bit nozzle is used to flush, cool, and lubricate the drill bit tips. The carbide nozzles may also clear stone chips in the well bottom with drilling liquid under high-pressure circumstances.
How many nozzles are there on a PDC bit?
It is most acceptable to construct two 16-mm centre nozzles and five 14-mm periphery nozzles. Finally, the overall optimization scheme of the drill bit is provided, which has a clear effect on timely improvement in field applications.
The nozzles is basing on the drill bit size and the relative equipment .
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.
