I recently had to redo my bathroom floor - it was four inches of concrete on wood, with two layers of tile and a protective layer on top. I did not expect this. Anyway, these beats got the job done quickly, even after the "Huh?!?" moment of observing two layers of tiles. We started with wide cutters but then realized we needed to clean the entire floor so we switched to wide cutters. Wide bits are also great for removing any type of tile. The suitcase is a nice bonus.
