Product Description
API Fixed Cutter Bit 9-1/2 Inch Diamond PDC Drill Bit of Oil Rig Drill Bit
1 . Descriptions:
Profile shape is one of the most important characteristics of fixed-cutter PDC drill bits, having direct influence on possibilities for cutter placement and densities and on hydraulic layouts. Profile also affects: PDC Drill Bit stability
PDC bits are designed for high speed drilling in shale, limestone, and sandstone formations. “Matrix” is a very hard, rather brittle composite material comprising tungsten carbide grains metallurgically bonded with a softer, tougher, metallic binder.
According to the International Association of Drilling Contractors (IADC), the Fixed-cutter PDC Drill bit classification composed of four characters that designate:
- PDC Drill Bit Body material
- PDC Drill Bit Cutter density
- PDC Drill Bit Cutter size or type
- PDC Drill Bit profile
All of our PDC Drill bits are fit for API standard and used in the drilling Industry.
The PDC drill bits size 3~22 inch with 3~9 Blades are available. And different classification cutter are optional according to your budget .

4 . PDC Drill Bit Cutters
Polycrystalline Diamond Composite (PDC) cutters are the main point of contact for a PDC 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 improve the clearing of cuttings.
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.
