💡 What is the best way to drill porcelain tile without chipping using a dry diamond drill bit set?

Here's a quick, handy guide: - Start with the included pilot bit to create a guiding dimple before switching to the diamond core bit. - Maintain steady speed and light pressure to prevent chipping on smooth surfaces. - Use the built-in wax cooling during dry drilling to reduce heat and extend bit life; switch to wet drilling for very hard stone like granite or marble if needed. ✝️
