NMLC/HMLC Natural Diamond Surface Set Core Drill Bits with Fast Penetration Rate

Application

The impregnated diamond bits are manufactured using high quality raw materials for optimum drilling performance. These impregnated bits present a metallic layer impregnated of diamonds on its cutting face. These impregnated bits are made by mixing fine diamonds with a metallic powder called matrix. The mixture is then subjected to heat treatment assuring the metallurgical bond of the matrix on the steel blank. To maintain optimal performance during entire bit life, it is important that matrix wear is synchronized with the diamond wear to ensure exposure of new diamonds with sharp edges.

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
