A ring saw blade is an ideal cutting tool for hard surface materials. It uses an abrasive coating, unlike other saws that use “blade teeth” for cutting. This abrasive coating allows them to be more stable while making precise cuts. They are very strong and can cut through hard materials like stone, marble, glass, and granite. Ring saw blades are abrasive rather than toothed. The brittleness of this abrasive coating, and the need to avoid flexure, is why they are made as rings rather than oval bands. As the ring is a circle of constant radius, the blade is not flexed or bent in operation.
