How does a diamond tool work?
A diamond tool consists of a support blade, a wire or drill tube, together with a cutting edge that has segments or beads containing diamonds. The segments or beads consist of a mixture of diamonds and a bond, usually a metal powder, which is sintered together under high pressure and temperature. The tool’s performance is related to the quality of the diamonds and the concentration of diamonds in the segments. When used, the diamond tool forms an increasingly deeper groove in the material that is being cut. The diamonds in the surface of the segments wear down eventually, at the same time as the bond is worn away to expose new diamonds. So it is also very important that the hardness of the bond is suitable for the material to be cut.
