Diamond Drilling Bit 12inch PDC Drill Bit of Open Hole Drilling Bit
Product Description
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 metallurgic ally bonded with a softer, tougher, metallic binder.
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 .

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 bits have the fixed blades with large, hard, abrasion-resistant cutters manufactured from a boned mass of microcrystalline synthetic diamonds and designed to excavate hole by shearing the formation while tricone insert bit works by crushing it.
Softer the formation and homogenous smaller the number of blades and bigger the size of the PDC cutters.
They drill very fast in soft to moderately hard formations as Sand, Shale, Clay and Siltstone.
