A table saw is a powerful woodworking tool designed for making straight cuts in various materials, primarily wood. It consists of a circular blade mounted on an arbor, which is driven by an electric motor. The blade protrudes through a flat table surface, allowing users to push the material against the blade for precise cuts. Table saws come in different types, including portable and stationary models, catering to various woodworking needs. They are essential for tasks like ripping lumber, cross-cutting, and making angled cuts. Safety features, such as blade guards and riving knives, are important to prevent accidents during operation.
