Masonry saws use a diamond saw blade to cut stone, brick, cinder block, and concrete. They have a circular blade that rotates to make wet or dry cuts. Wet cutting reduces airborne contaminants and keeps the blade cooler, extending blade life. Dry cutting requires a dust collection system to keep dust to a minimum. Benchtop saws are stationary. Handheld saws can be brought to a workpiece and are used when it isn't possible to bring the workpiece to the saw.
