A guard for a circular saw having a pair of cranked supports pivotally mounted to the work table at either side of the saw blade, an arm pivotally mounted to the supports extending in line with the saw blade and above it, and a guard member pivotally mounted to the arm having parallel limbs spaced apart and disposed at respective sides of the upper periphery of the saw blade to guard it. There is a plate which joins these arms and which extends transversely of the saw blade to prevent articles cut out from the work piece from being violently ejected from the vicinity of the saw blade. The supports also pivotally carry a plate which is in line with the saw blade and movable between an operative position in which an edge of the plate lies closely adjacent the rear edge of the saw blade, and an inoperative position in which the blade is raised above the table. A further guard member for the front edge of the saw blade extends down from the arm in front of the blade. This guard member is a rotatable wheel displaceable relative to the arms. Workpieces to be cut are fed under the wheel to the saw blade. An adjustable fence for guiding the cutting of workpieces is also provided.
