Tile and glass punish careless drilling, but a few habits keep holes clean and cracks away. Here is the short version.
Pick the right bit tip
Smooth, glazed surfaces need a carbide or diamond tip built to bite hard material. A pointed cross head resists the skating that ruins the first few seconds of a cut.
Stop the bit from wandering
Mark your spot and start slow. A cross-head tip anchors the bit so it stays put. Some people add tape over the mark for extra grip on slick tile.
Match speed to the material
Follow the maker's RPM guidance, often at least 2000 RPM. Let the bit do the work at a steady pace rather than leaning hard, which only builds heat and stress.
Drill wet where you can
Water carries away heat and debris and, per most makers, lengthens bit life. A diamond tile drill bit set with carbide tips holds up better when you keep the cut cool.
Ease through the back
As the bit nears the far side, lighten pressure. That final easing helps avoid blowout and the chips that crack tile edges at the exit hole.
The bottom line
Right tip, controlled speed, water, and a gentle finish. Follow those and clean holes in tile or glass stop feeling like a gamble.
