Depending on the range of application as well as the cutting media on the core bits, Hanlinsky makes six types of core bits:
• Impregnated Diamond Type
• Surface set Diamond Type
• Tungsten Carbide Type
• PDC Type
• PCD Type
• Electroplated Diamond Type
Generally, an overall drilling system consist of core bits, reaming shells, core barrels, drill rods and drilling rig. Core Bits are used for drilling materials like the rock, concrete, limestone, granite, marble, clay, basalt, schist, quartz etc..
Impregnated Diamond Core Bits are manufactured with very small, high quality synthetic diamonds, mixed evenly through a metal alloy matrix. The matrix erodes away at the same rate as the diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock. In most geological formations, impregnated bits are more economical to use than other bits.
