A bandsaw is a power tool which uses a cutting blade which consists of a band of metal with serrated teeth along one edge to cut various materials. The saw blade (band) usually rides on two wheels rotating in the same plane, although some bandsaws use three wheels.

Bandsaws have the benefit of providing a relatively smooth cut due to the evenly distributed cutting forces provided by the blade. Bandsaws are commonly used for woodworking, metalworking, or for cutting a variety of other materials. Bandsaws are particularly good at cutting irregular or curved shapes, however they can also be used to produce straight cuts.
