Geological NQ Core Bit Customized Size Shape Non Hole Hole Shrinkage
Product Description
Impregnated diamond core drill bits are widely used in engineering
surveying, geological exploration, water conservancy and hydropower
construction, water well drilling and other aspects. This
impregnated diamond core drill bit cainternal body adopt carefully
selected high-quality synthetic diamond, while the carcass,
continued to wear and tear, there have been a new diamond
protrusion to keep the drill bit fast drilling.
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.
