hi There if youur using a grinder which is perfectly fine, make sure its an electroplated Blade with a continuous rim finnish this will reduce chipping. The raeson for electroplated is the diamond is exposed as opposed to diamond held within the metal bond commonly used for cuttting porcelain and ceramic. Metal bonded blades tend to glaze over and become smooth when cutting large quantities of travertine, marble and other very soft natural stone tiles. Never use an electroplated blade on porcelain, the blade will cut fine but will wear out very quick. Hope this helps. When dry cutting usinga grinder always use a dust mask!!!
