ABSTRACT:
A method of forming a rotating blade for a cutting machine that can attach to either symmetrical arbors or asymmetrical arbors. The arbor mounting hole has five sides arranged in a cut gem configuration. The arbor mounting hole is symmetrical on either side of a mid-line. However, the mid-line of the arbor mounting hole need not pass through the geometric center of the blade. Inserts are provided. The inserts fit into the arbor mounting hole. Each of the inserts defines an aperture for receiving a drive arbor of a different configuration. The apertures are off-set in the inserts, to compensate for the off-set arbor mounting hole, so that the apertures are disposed at the geometric center of the blade when any insert is placed in the arbor mounting hole.
