A wet saw is a power tool used for cutting tile, stone, and other hard materials. It features a diamond blade that is cooled and lubricated by water during the cutting process. This helps to reduce dust and prevent the blade from overheating, ensuring cleaner cuts and longer tool life. Wet saws are commonly used in construction and home improvement projects, especially for installing ceramic tile or granite countertops. They come in various sizes, from portable models for small jobs to larger, stationary versions for professional use. Proper safety precautions should always be taken when operating a wet saw.
