A band saw is a power tool that uses a long, continuous blade with teeth to cut various materials, primarily wood and metal. The blade is looped around two wheels, allowing it to move in a continuous motion. Band saws are known for their ability to make straight cuts, curves, and intricate shapes, making them popular in woodworking and metalworking industries. These saws come in various sizes and types, including portable and stationary models. They are often used in carpentry, metal fabrication, and even in food processing for cutting meat and cheese. Band saws are valued for their precision and versatility.
