A table saw is a powerful woodworking tool designed for making straight cuts in various materials, primarily wood. It features 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 contractor saws, cabinet saws, and portable saws, each suited for specific tasks and environments. They are essential for both professional carpenters and DIY enthusiasts, providing accuracy and efficiency in cutting large sheets of material.
