A table saw or sawbench is the most common piece of large wooworking equipment. Because of its versatility, when only one piece of large woodworking machinery is owned, it will often be a table saw. The saw consists of a circular saw blade, mounted on an arbor, that is driven by an electric motor (either directly, by belt, or by gears). The blade protrudes through the surface of a table, which provides support for the material (usually wood) being cut.
