Saw blades are cutting tools used in various applications, primarily for cutting wood, metal, or other materials. They come in different shapes and sizes, designed for specific tasks. Common types include circular blades, band saw blades, and reciprocating saw blades, each suited for particular cutting techniques and materials. The teeth of a saw blade are crucial for its performance, as they determine the cutting speed and finish. Materials used for saw blades often include high-speed steel or carbide, which provide durability and sharpness. Proper maintenance, such as sharpening and cleaning, is essential for extending the life of a saw blade.
