摘要： A saw blade includes a circular body having teeth defined in the outer periphery thereof and a central hole is defined through the center of the circular body. The circular body has an inner annular area and an outer annular area, the inner annular area extends radially outward from the central hole to a radial distance of the circular body and the outer annular area extends from the outer periphery of the inner annular area to the outer periphery of the circular body. The outer annular area is narrower than the inner annular area, the outer annular area is thinner than the inner annular area, and the teeth are thicker than the outer annular area. The thinner outer annular area does not contact the object to bet cut. The wider inner annular area supports the narrower outer annular area.
