Impregnated Diamond Core Bit

     The impregnated diamond bits are the most commonly useful bits in the mineral exploration industry, as they have the widest range of application. The carefully selected grades of high quality synthetic diamond are distributed in the depth of impregnated bit's matrix series. The matrix layer of the crown contains a uniform distribution of these crystals that are embedded in a powdered metal bond
 
     The matrix of our impregnated bits is designed to expose new diamonds to the bits' cutting face as wear occurs. Fast penetration rate is maintained as a result of this action. Our impregnated bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.|

    The optimum diamond size, concentration and matrix type are dependent on the hardness and abrasiveness of the formation to be drilled

Surface Set Diamond Core Bit

 

     Surface-Set Diamond Bits are set with a singular layer of natural or synthetic diamond utilizing a hard matrix compound on the face of the bit. The diamond set design ensures sufficient overlap to prevent premature wear of the matrix.

    
Surface-Set diamond bits are primarily recommended for use in drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bits. They are also recommended for use in drilling harder formations where the available rotational speeds and bit loads are insufficient to use impregnated diamond bits due to drilling equipment limitations.


Electroplated Diamond Core Bit

 
    The bit crown of electroplated diamond core bits are electroplated with layers of synthetic diamonds in the electroplated liquid under certain strictly controled conditions. The whole producing process is carried on in a room temperature that can avoid diamond oxidation and degradation
      Electroplated diamond core bits obtain much faster penetration than impregnated diamond core bits in drilling soft to hard, competent formations. It is similar to the impregnated diamond core bit, for drilling different rock formations, the matrix hardness of electroplated diamond core bit could be different, please refer to "Matrix Selection Index

 PDC Core Bits
 
     Polycrystalline diamond cutters are set on the crown giving a very long working life, very fast penetration and high percentage core recovery in soft to hard rock formations. The bit may be used with air, mud, or foam flushing
      PDC bits are an alternative to T.C. Bits and Surface set diamond bits, when drilling in non-consolidated and medium hard rock formation.

 Construction core bits
 
     Polycrystalline diamond cutters are set on the crown giving a very long working life, very fast penetration and high percentage core recovery in soft to hard rock formations. The bit may be used with air, mud, or foam flushing
      PDC bits are an alternative to T.C. Bits and Surface set diamond bits, when drilling in non-consolidated and medium hard rock formation.
