Bandsaw
（重定向自Band Sawing）
A bandsaw is a power tool which uses a blade consisting of a continuous band of metal with teeth along one edge to cut various workpieces. The band usually rides on two wheels rotating in the same plane, although some bandsaws may have three or four wheels. Bandsawing produces uniform cutting action as a result of an evenly distributed tooth load. Bandsaws are used for woodworking, metalworking, or for cutting a variety of other materials. They are particularly useful for cutting irregular or curved shapes, but can make straight cuts. The minimum radius of a curve that can be cut on a particular saw is determined by the width of the band and its kerf.
