To drill into porcelain stoneware and tiles, you will need a carbide-tipped masonry drill bit specifically designed for hard materials like porcelain. Before drilling, mark the spot with a pencil and place a piece of masking tape over it to prevent the drill bit from slipping.

It is also recommended to use a spray bottle with water to keep the drill bit and tile cool during the drilling process. **
