Review on Dremel MM500 1/8-Inch Multi-Max Carbide Grout 🔧 Blade: Optimal for Grout Removal, with Durable Gold Coating by Gregory Plump

Used this on my Multi-Max Dremel to refill my bathroom grout and it's amazing. Removes grout quickly and easily and never seems to wear off. One caveat: if your tiles are less than 1/16 inch apart like mine, it will cut into the tile. This wasn't a problem for me - I have white tile and I used white grout so you can't tell the tile is a little nicked. In fact, I now have even tile spacing throughout the bathroom, so the result is positive. I would just say drive slowly and let the car do its job. If you use too much force, the tile will break. Position the machine so the blade is clearly visible and move the blade in a straight line along the grout line, avoiding hitting the edge of the tile.
