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


Description of Goods


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

Advantages


1. Many years of experience combined with recent improvements in technology and manufacturing concepts have resulted in greatly improved drilling performance of impregnated PQ HQ NQ BQ diamond core bits.
2. High quality synthetic diamond powders are distributed in the depth of impregnated diamond core bit's matrix series. The matrix layer of the crown contains a uniform distribution of these crystals that are embedded in a powdered metal bond.
3. The matrix of our impregnated diamond core bits is designed to expose new diamonds to the bits' cutting face as wear occurs. Fast penetration rate is maintained as a result of this action.
4. Our impregnated diamond core bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.
