Porcelain tiles are exceptionally hard. But they are also prone to breakage if you need to drill a hole through one of them without using the proper technique. With the right tools you can drill a hole through a porcelain tile and not have to worry about cracking it.
|Step 1||Put on your safety glasses and gloves. Porcelain is a type of glass and is extremely sharp.|

|Step 5||Remove the drill guide. Place the drill directly on the spot you left in Step 3. Hold the wet sponge under the drill bit with your left hand.|
