Diamond Grinding Information

A diamond tool is a cutting/grinding tool which contains diamond segments for grinding through a wide variety of materials which other cutting tools cannot. The segments are composed of diamond crystals and powder metal which form the bond, or 'matrix', of the segments.

The bond is one of the main factors when selecting which tool to use for diamond grinding a certain material depending on how hard, or abrasive, the material is. The bond is what decides the rate at which the metallic powders wear down and expose new diamond crystals at the surface to maintain what would be considered a “sharp” edge.

For grinding hard materials, a diamond blade with a soft bond would be needed. This means the metallic powders in the segments (teeth) of the diamond blade wear fast enough to release old, dull crystals, exposing new diamond at the edges to continue cutting efficiently. Inversely, to cut a soft abrasive material like asphalt or freshly poured concrete, you would need to use a diamond blade with a hard bond so that the segments do not wear down prematurely and the blade is not put to waste.

The diamonds used in these tools are synthetic or natural industrial diamond of different grain sizes and shapes.
