Yes, they are safe to use on limestone. However, it is highly recommended that you use the clear view shield protection plates to avoid any scratching. With that said, as with any moisture sensitive material we would recommend that you do a sample board with the material to ensure that there will not be any scratching or moisture rings left behind. Also, calcium based stones like limestone and marble are much more delicate and do not have the same edge pressure as porcelain so be sure to get the tile as flat as possible and use the Spin Doctor for micro-adjustments only.
