SML BQ NQ HQ PQ Core Barrel Backend Head Assembly

Impregnated Diamond Core Bits are produced by very small, carefully selected grades of high quality synthetic diamonds mixed evenly through a metal matrix. They are attached to the foremost part of the core barrels to be used in direct drilling of the ground, and play the most significant role among the drilling equipments. Impregnated diamond core bits have emerged the most commonly used bits in mineral exploration industry and are particularly well suited for drilling in hard, consolidated and non-abrasive formations.

Impregnated Diamond Core Bits are attached to the foremost part of the Core barrels to be used in direct drilling of the ground, and play the most important role among the equipments that are used in drilling. Impregnated Diamond Core Bits are normally used in case Core is needed, they are more economical to use than other bits. Impregnated Diamond Core Bits are used for drilling materials like the rock, concrete, limestone, granite, marble, clay, basalt, schist, quartz etc..

Polycrystalline Diamond Compact (PDC) Core Bit have numerous sintered-polycrystalline-diamond studs on the matrix. The bigger the bit, the higher the number of studs on it. These PDC stud cutters have great wear resistance and are designed to shear the rock and get deeper penetration. The size, number and layout of the cutters can be varied to suit the rock hardness, abrasivity and other details of the application. Applied to rock formations of f≤10.
