A band saw is a power tool used for cutting various materials, primarily wood and metal. It features a long, continuous blade that runs on two wheels, allowing for smooth and precise cuts. The blade's design enables it to make straight cuts, curves, and intricate shapes, making it a versatile tool in woodworking and metalworking. Band saws come in different sizes and types, including portable and stationary models. They are commonly used in workshops, factories, and home garages. Safety features, such as blade guards and emergency shut-off switches, are essential to prevent accidents while operating the saw.
