A concrete saw is a power tool designed for cutting through concrete and other masonry material. It utilizes hand-held operation or walk-behind, similar to a tiller. A concrete saw can have a chain, circular, or jig blade, like many other varieties of power saws,. Powered by electricity, gasoline, air, or hydraulics, a concrete saw uses either abrasive or diamond blade cutting technology and is designed for either dry or wet sawing.

There are a number of applications for a concrete saw. Brick, concrete, and cement can be cut out for repair, demolition, or modification.
