Product Description
Surface Set Drill Bits 3-1/2 Inch Nature Drill Bit For Hard Rock Drill Bit
1 . Descriptions:
The main types of fixed drill bits are: PDC (polycrystalline diamond compact), TSP (thermally stable PDC) and diamond bits.
All of the bits are affected by below factors :
- PDC Drill Bit Body material
- PDC Drill Bit Cutter density
- PDC Drill Bit Cutter size or type
- PDC 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 . 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
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.
