A band saw blade is a long, continuous strip of metal with teeth along one edge, designed for cutting various materials such as wood, metal, and plastic. It is used in a band saw, a power tool that allows for precise and intricate cuts. The blade's flexibility enables it to navigate curves and angles, making it ideal for both straight and curved cuts. Band saw blades come in different sizes, tooth configurations, and materials, depending on the intended application. Common types include bi-metal blades, which combine toughness and flexibility, and carbide-tipped blades, known for their durability. Proper blade selection is essential for achieving optimal cutting performance.
