Abstract: A band saw attachment releasably secured to the quill of a vertical milling machine and driven by the rotary spindle of the machine is movable with the quill generally toward and away from the work-support surface of the machine table and may be tilted with the quill and relative to the support surface to provide clearance between one portion of the saw blade and the work-support surface. Blade guide rollers are mounted on the attachment to twist a portion of the saw blade to a normal position relative to the work-support surface when the quill is tilted relative to the support surface.
