NQ NQ3 HQ HQ3 Surface Set Diamond Core Drill Bit for Drilling
Broken and Backfilled Stratum Shale
Surface Set Diamond Bit
Roschen surface-set diamond bits are 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.
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 formations where the
available rotational speeds and bit loads are insufficient to use
impregnated diamond bits due to drilling equipment limitations.
Surface-Set Diamond Bits Surface-Set non-coring bits are drilling
for broken formation rock which can't be cored. Crown is used to
set with synthetic, natural or polycrystalline diamond. It's used
for drilling in soft to medium hard formation rocks.
