Surface Set Diamond Core Drill Bits For Unconsolidated Formations
The 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.
Notice :
To select the right bit for the job, assess the speed and power of your drill for the size and depths of the holes to be drilled and assess ground conditions such as rock type/formation and down-hole conditions.
Size:
SINOCOREDRILL bits are available in all standard drilling sizes . Also, non-standard sized bits can be produced according to requirements from clients.
Crown Height:
SINOCOREDRILL offers crown impreg depths of 9mm, 12mm, and 16mm .The taller crown heights provide improved bit stability and reduced vibrations, enhancing bit life and performance.
Waterways:
Various waterways are available for diamond impregnated bits. Differing waterways allow for better flushing in various ground conditions and drilling systems.
Matrix:
SINOCOREDRILL impregnated bits matrices can be selected by our engineer according to ground conditions at client's work site.
Threads:
standard Q threads as well as thread types required by clients are available.
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.
