Diamond Core Drill Bits  NMLC / HMLC  core bit For Mineral Exploration

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:
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.
