💡 What is the best way to drill through porcelain tile with a diamond core bit and hole saw set?

Here's a handy guide to get clean, precise holes:

- Start at a slight angle at low speed with light pressure. - Keep water flowing to cool the diamond tips and extend bit life. - Use a steady, controlled feed and let the diamonds do the work. - Deburr and inspect the edge after drilling.✝️
