Porcelain blade to cut ceramic/porcelain/vitrified paving, granite and very hard materials. Better when used with water. 115mm with 22.2mm bore or 230mm with 22.2mm bore. The P1-DCC can be used wet or dry & on an electric angle grinder or battery saw. As with all blades when cutting porcelain it is better if you can cool the blade with water. Close segmented rim. Neat cut with the minimum of shelling.
