MBD
Metal Bond Diamond
MBD diamonds are made from selected high-quality diamonds, which are manufactured through processes such as pressing, purifying, drying and selection. Compared with RVD, the crystal is regular, smooth surface, high purity, good color and transparency, high strength, high thermal stability and compact resistance.

MBD series: MBD2, MBD4, MBD6, MBD8, SMBD.

The higher the diamond grade is, the better the following elements are, including crystal shape, impurities, hardness, wear resistance, thermal stability and impact resistance.

Available sizes: from 20/25 US Mesh to 70/80 mesh.

 

Usage:

For making metal bond or electroplated diamond tools, diamond drill bits, diamond saw blades, diamond grinding wheels, etc.

Premium Grades

SMBD

The strongest grade in metal bond diamond. Cubo-octahedral crystal shape with high purity, very high strength, superior thermal stability and impact resistance

 it is recommended for high demanding applications in tough environments.

MBD8

Good cubic crystal shape, good color and diaphaneity, high strength and thermal stability

Ideal for sawing, drilling and grinding in high strength applications.

Standard Grades

MBD6

Regular crystal shape, good diaphaneity, good strength and thermal stability

Ideal for making tools for medium hard materials, like ceramic, granite, concrete, etc.

MBD4

 Relatively regular crystal shape, medium high strength and thermal stability

Ideal for making tools for medium and low load non-ferrous materials, such as common concrete, marble, etc.

Economy Grade

MBD2

Irregular but blocky shape with relatively low strength, high brittleness.

Suitable for making metal bond tools working in low load conditions.
