Panel saws have a vertical work surface and cut or rout straight lines in sheet goods and other long workpieces. The vertical orientation takes up less space than a table saw and allows the saw to be moved around in small shops. Panel saws support the workpiece to move the saw through the workpiece, allowing one worker to cut large and heavy sheet goods. Panel saws keep a worker's hands a safe distance from the blade. Router panel saws make through and plunge cuts to mill through and blind rabbets, grooves, and dados. Corded panel saws plug into a wired power source. Panel saws are often used in cabinetry shops and lumber supply stores.
