A hole saw has an arbor and a cup shaped cutting member. The cup shaped cutting member has an annular skirt with a plurality of teeth at its free end. A drill bit is secured on the arbor. The drill bit includes a pilot point with a first cutting edge. A second edge is formed on the body portion of the drill bit to form a constant diameter hole in the workpiece.
