Core Drill Bits Hard Rock Geological Drilling Impregnated Diamond
Bit
The impregnated diamond bits are the most useful bits in the
mineral exploration industry, becasue 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. In most geological formations, impregnated bits are
more economical to use than other bits.
The bit mainly consists of diamond, steel body, carbide powder and
polycrystalline diamond. The polycrystalline diamond is utilized to
avoid too much abrasion of drill bits. The impregnated diamond is
synthetic diamond (also called artificial diamond), which costs
less but is more suitable to be used in drilling hard formations.
