A specialized, often hand-held, power tool used for cutting hard materials, ceramic tile, metal, concrete, and stone is known as a disc cutter. This tool is very similar to an angle grinder, chop saw, or even a die grinder, with the main difference being the cutting disc itself (a circular diamond blade, or resin-bonded abrasive cutting wheel for a disc cutter vs. an abrasive grinding wheel for an angle grinder). This tool is very effective in cutting very hard materials, especially when compared to hand tools.
