A circular saw blade is a round cutting tool used in various power saws, primarily for cutting wood, metal, or plastic. It features sharp teeth around its edge, which rotate at high speeds to slice through materials efficiently. The size and type of the blade can vary, depending on the specific cutting task and the material being worked on. These blades come in different diameters and tooth configurations, such as rip blades for cutting along the grain of wood and crosscut blades for cutting across the grain. Proper selection and maintenance of a circular saw blade are essential for achieving clean cuts and ensuring safety during operation.
