Product Description

NWL3 (NQ3) Impregnated Diamond Core Drill Bits With High Performance Drilling



Description of Goods

Impregnated Diamond Core Bits are manufactured with very small, high quality sythetic diamonds, mixed evenly through a metal alloy matrix. The matrix erodes away at the same rate as the diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock. In most geological formations, impregnated bits are more economical to use than other bits.


 

The main technical parameters of impregnated diamond core bits include diamond type, size, concentration and diamond grade, matrix hardness and crown shapes,waterways etc. If users can make rational selections according to the geological formations, they can get satisfied drilling performance on various formations with different hardness. To avoid excessive bit wear, diamond tungsten carbide inserts could be used on both sides of the waterway and the larger diamonds are used on the inside and outside.

The impregnated diamond core bit emerged as the most commonly used type in the mineral exploration industry.

NQ3 Diamond Core drill Bit is a kind of diamond drill bit used for cutting soft to hard rock in geological investigation.

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.

Features:
1. High Performance drilling equipment;
