Picture shown is not the actual size of the blade. The Cyclone 4,5" mesh rim blade is designed specifically for making straight cuts on porcelain tile and harder granites (softer stones and tile will quickly glaze over the diamond matrix). This blade is very sensitive to lateral pressure: do not attempt to cut a radius or apply pressure to the side of the blade as it will fracture at the rim. This is considered misuse of the product and is not warranted.
