Surface set diamond core bits are set with a singular layer of natural 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 formation where the available rotational speeds and bit loads are insufficient to use impregnated diamond bits due to drilling equipment limitaions.
