Great for small areas, but the guard is annoying.
on April 11, 2017
We recently moved into a new-to-us home that had a tile tub in need of some TLC. I assembled the tools I thought I'd need, and found this online with some positive reviews so I added it to my arsenal of grout busting equipment. I will admit that the bit does work really well, but you have to be careful because it will also quickly score your tile. I didn't remove and re-grout the entire tub, just the soap holder area and some of the lower grout near the tub line. I was surprised to find that the larger / longer seams I actually preferred a normal tile saw over this tool in the Dremel, but in the nooks and cranny's where a sawing motion is difficult or impossible this was a clear winner. I also got away from using the guard as well because in those smaller corners it was difficult to maneuver anyway, but I didn't have any trouble keeping the proper angle on the bit for a clean removal.
Long story short, if you are just removing grout from a solid wall with no small crevices to deal with, I'd probably say skip the Dremel tool and just use a grout saw, but if you have some small nooks and corners like I did, this was a lifesaver.
