NMLC / HMLC core bit
This type of bit is primarily recommended for use in drilling
relatively soft, abrasive, unconsolidated formations that are not
effectively drilled by impregnated diamond bit. It is also
recommended for use in drilling harder formations where the
available rotary speeds and bit loads are insufficient to use
impregnated diamond bits due to drilling equipment limitations.
In most cases, surface set diamond bits will provide higher rates of penetration than in softer formations due largely to the greater degree of exposure of the individual diamond crystals.
Use :
NMLC surface set diamond core bits are widely used for the site investigation and mineral exploration.
NMLC Surface set diamond core bits can be used with NMLC core
barrels.
NMLC surface set diamond core bits are primarily recommended for
use in drilling relatively soft, abrasive, unconsolidated
formations.
In most cases, Surface-set diamond core bits will provide higher
rates of penetration than in softer formations due largely to the
greater degree of exposure of the individual diamond crystals.
Drill soft to hard rock, widely used in all kinds of drillings for prospecting, water and electricity building and construction industry of road, railway, bridge and building taking out core to examine stake, etc

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:
ROSCHEN bits are available in all standard drilling sizes . Also,
non-standard sized bits can be produced according to requirements
from clients.
Crown Height:
ROSCHEN 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:
ROSCHEN 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.
