Abstract
An improved circular saw blade is provided which has a plurality of dimples formed on the body of the blade by cold-working the blade. The dimples each include a circumferential ridge which extends above the surfaces of the blade's body. When a side load is applied to the work piece, the ridges contact the one of the walls defining the kerf being cut that is forced by the load against the blade, so that the surface of the blade's body is spaced from the wall. The dimples are formed by cold working the blade, which stiffens the blade, reducing the vibration of the blade during the cutting process. The dimples and their ridges also provide greater heat dissipation, and tend to provide a laminar flow of air over the surface of the blade, acting much as the dimples of a golf ball.
