Hard Rock Drill Bits 17inch PDC Drill Bit of Oilfield Drill Bit
Description :
There are no moving parts in a fixed cutter bit; the cutting structures and bit body rotate as one unit. PDC (polycrystalline diamond compact), TSP (thermally stable PDC), and diamond bits are the three primary categories of these bits.
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
- others
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 .

Drill Bit PDC Cutters
Cutters made of Polycrystalline Diamond Composite (PDC) are a drill bit's primary point of contact. PDC bits primarily chop the rock out of the way.
The PDC cutters operate in a highly difficult environment with frequent heating and cooling of the well.
PDC cutters with greater thermal stability and less thermal deterioration typically have higher ROP and stronger wear resistance. Therefore, the cutter needs to be optimized.
Drill Bit Nozzles
The Polycrystalline Diamond Composite (PDC) cutters are kept cold and the cutting zone is cleared by drill bit nozzles.
The positioning of these nozzles and the angle at which they are set have a significant impact on how effectively the drill bit operates.
Additionally, fluid channels work in conjunction with nozzle location to enhance cuttings removal.
Steel Body PDC Bits
The antithesis of a matrix body is a steel body. Although it is softer and lacking protective features, it is capable of withstanding severe impact loads. Steel bit bodies provide a high level of impact resistance due to the strength and ductility of steel.
Matrix bodies are significantly weaker than steel bodies.
Steel bits have the advantage of being easily rebuilt multiple times due to the ease with which worn or damaged cutters can be swapped out. Operators who operate in low-cost drilling environments will particularly benefit from this.
In contrast to roller cones, polycrystalline diamond compact (PDC) drill bits have a single, non-moving body. In consolidated formations, the bit can operate at faster rotation rates because the fixed-cutters efficiently shred the rock.
Drill Bit PDC Cutters
It's crucial to first recognize the significance of Polycrystalline Diamond Compact (PDC) Cutters.
PDC Cutters improve the functionality of PDC drill bits by increasing their dynamic stability in a variety of difficult vertical and directional drilling applications.
One-of-a-kind polycrystalline diamond cutter has exceptional strength, hardness, and toughness.
It is therefore perfect for a variety of material removal (cutting) procedures.
PDCs are produced utilizing tungsten carbide, diamond, high pressure, and heat.
Why choose PDC Drill Bit
PDC has been used with great success in the oil field, and has recently become a go-to technology for many drillers in the Waterwell and HDD industry.
The primary reason for wanting to run PDC bits is increased production. When run properly, a PDC bit can increase your penetration rate from anywhere between 50-250%. This translates to faster project completion, fuel savings and reduced labor costs per hole.
Another benefit of running PDC is how much little stress they place on drill rigs. They do not require the enormous amount of weight on bit that roller cones require, and as a general rule of thumb, PDC bits and reamers require less than half of the push/pull that a roller-cone would. Less torque means less stress and vibration on your drilling rods.
PDC products also have no moving parts and clean holes with a more consistent cutting size.
