A blade guard is configured to surround a rotatable cutting blade. The blade guard includes an arcuate body mounted to surround a portion of an outer circumferential edge of the cutting blade, wherein the arcuate body is fixed with respect to the rotatable blade. A plenum is disposed upon the body and configured to provide fluid communication between a cutting zone within the body and a suction source. An aperture is defined in the body proximate the cutting blade, the aperture disposed proximate a location where the cutting blade exits a workpiece being cut.
