ABSTRACT:
Disclosed is a power driven circular saw blade and a guide assembly for such blade where the guide assembly includes a pair of guide units mounted respectively one of each of opposite side of the blade. Each guide unit includes a guide housing with a guide block reciprocally mounted therein and having a saw blade engaging portion. A stop limits movement of the guide block at least in a direction of movement toward the blade so that the guide block is normally in non-engagement with the saw blade while the latter is in a smooth substantially vibration free running condition. The guide block is resiliently biasing against such stop preferably by pneumatic pressure. A guide assembly as described is preferably located at the outfeed side of the blade but there may be an assembly at both the infeed and outfeed sides of the blade. The position of the stop if preferably adjustable.
