Diamond Drilling Tool 22inch S819 Oilfield Rock PDC Rock Drill Bit
Product Description
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 from 3~22inch with 3~9 Blades are available. And different classification cutters are optional according to your budgets .

Bit Profile
Nozzles
The Polycrystalline Diamond Composite (PDC) cutters are kept cold and the cutting zone is cleared by 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.
PDC Cutters
Cutters which made of Polycrystalline Diamond Composite (PDC) are a drill bit's primary point. 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.
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.
PDC bits have the advantage that they last longer- you can usually drill shoe to shoe, eliminating tripping, and can often be rerun (with or without refurbishment) on subsequent wells, reducing the cost per foot if you have a number of wells to drill.
The PDC bit is now almost the default choice unless you can't use a PDC bit: really plastic, sticky formations or really hard formations (and PDC technology is encroaching into these areas with depth of cut limiters and the like).
