Metal-cutting band saw machines fall into two basic categories that are vertical machines, which are also called as contour machine made in a variety of sizes and models by several manufacturers and horizontal machines which does the same job as the power hacksaw but does it more efficiently. Ban d saws use a continuous saw blade. Chip removal is rapid, because each tooth is a precision cutting tool and accuracy can be held to close tolerances eliminating or minimizing many secondary-machining operations. It is mostly suited for steel service centers because of the array of grades, shapes, and specialization handled by the service center, a saw must be all-purpose and band saw, with a few exceptions, can do almost everything.
