The price of this hole saw set is hard to beat. Moisten the tile to be cut with a little water so that the saw blade stays wet and it even cuts through porcelain stoneware. The suction cup on the mounting fixture may not work on all surfaces or conditions, but you can use another person or a clamp to hold it if needed. You will need to use a setting tool to guide the hole saws as they don't have guide tips and will definitely run when you start cutting.
