Abstract
The present invention relates to a circular saw blade comprising a first annular saw blade having a plurality of teeth projecting radially from the periphery thereof and a second circular saw blade having a plurality of teeth projecting radially from the periphery thereof. The first blade has a greater diameter and a smaller thickness than the second blade and the teeth on the first blade are angularly set so as to partially extend into the cutting plane of the second blade. The blades are mounted coaxially adjacent to one another such that when used to cut through a workpiece, the first blade makes a fast rough cut and the second blade follows partially within the path of the first blade and provides a smooth, finished cut.
