Working with glass is tricky: it’s brittle, it can crack or chip, and heat is your enemy. To drill clean holes, you need the right tool, proper technique, and suitable conditions. If you want clean, precise holes in glass, the best drill bit is usually diamond-tipped (or sometimes high-quality carbide) used in a drill with low speed, with light pressure, proper cooling, and good support.
