Finer cutting discs due to having small abrasive grains enable finishing cuts with precision. These discs are used for making incisions that require accuracy as well as smoothness. In the jewelry industry, fine grained cutting discs enable incredibly precise cutting and shaping of gemstones. They are also used in the semiconductor industry for making precise cuts on silicon wafers. The small grains result in a more controlled cutting process thereby reducing the amount of material wasted and improving its quality. Fine grained cutting discs are used after coarse grained discs to enhance the surface of a previously made cut.
