A table saw blade is a circular cutting tool designed for use with a table saw. It features sharp teeth that slice through various materials, primarily wood, to create precise cuts. Blades come in different sizes and tooth configurations, allowing users to choose the right one for specific tasks, such as ripping or crosscutting. The material of the blade can vary, with options like high-speed steel (HSS) and carbide-tipped blades being common. Carbide-tipped blades are particularly durable and maintain sharpness longer, making them ideal for heavy-duty use. Proper blade selection enhances cutting efficiency and quality in woodworking projects.
