These need to be used in the same size as that of the Grinding Tools for Concave Machines.

If your Gemstone is hard and big size and you need to pre shape, a coarser grit (80 to 360) is preferred. The fine grits (600-3000) to be used for stones that are soft, small and the operation required is faceting or pre-polish. Grit Laps come as wrappers only and a Grit Lap base is required for each of them. Select your grit Size(s)
