Masonry, tile, and concrete saws are used by contractors and road crews to cut brick, tile, concrete, and stone. Masonry saws use a diamond saw blade to cut stone, brick, cinder block, and concrete. Walk-behind concrete saws are wheeled to allow the worker to push the saw in a straight line to cut inlay lines and trenches in roads, sidewalks, and other concrete surfaces. Handheld concrete saws are portable and use diamond saw blades cut masonry, stone, and reinforced concrete. Tile saws are used by contractors to cut floor, kitchen, and bathroom tile to size.
