About products
Surface-Set Diamond Bitsare 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.

Usage:
Surface-Set diamond bitsare 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.
PDC bits are used for water well drilling, geotechnical and environmental drilling, mineral exploration, geothermal wells, geothermal drilling, construction and utility work
