    PDC Diamond Drill Bit 12-1/4 inch Matrix Body PDC Rock Bit

    PDC Diamond Drill Bit 12-1/4 inch Matrix Body PDC Rock Bit


    1. Description :


    Steel is the opposite of matrix. 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


    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 .

    3. Bit Profile

    4. 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 . 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. Matrix Body


    Matrix is a very hard, rather brittle complex material containing tungsten carbide grains bonded with a softer, tougher, metallic binder.


    The hardness of a matrix-body PDC has the benefit of not being susceptible to abrasion and erosion. It is effective in tolerating high compressive loads, but, compared with steel, has low resistance to impact loading.


    Matrix-body PDC bits are relatively diverse, because matrix is a compounded material.

    In environments in which body erosion is likely to cause a bit to fail, matrix-body PDC are the preference over steel-body bits. For diamond-impregnated bits, only matrix-body construction can be used.
