Stone cutting band saws. Common in mining industries band are used to cut hard stone into large that can then be shipped to processing plants to be further refined. These saws use the same principals as other band saws but with one major difference. The major difference is that instead of a thin flat blade these use a thick cable.
Meat band saws. Saws for cutting meat are typically of all stainless steel with easy to clean features. The blades either have fine teeth with heat treated tips, or have plain or scalloped knife edges. The heat treated blades designed for meat saws are also used for hard plastics and laminates.
Automated saws. Automatic band saws feature preset feed rate, return, fall, part feeding, and part clamping. These are used in production environments where having a machine operator per saw is not practical. One operator can feed and unload many automatic saws.
