Here's my problem, I need to add a short wall in my kitchen and have a ceramic tile floor. Normally I would just remove the tile where I need to attach the sill plate, but I don't have any extra tile. I need to cut out the pieces of tile under the sill without damaging the surrounding tile. I'm afraid I'll break the tile and end up having to mickey mouse something. Can I cut the tile with a grinder and abrasive wheel while its attached to the slab?
