Question: How do I drill into tile without breaking it?
You’re correct in assuming that this is a precarious thing to do. Even when you’re taking the utmost of case, tile breakage can result.
So how do you drill into tile?
Answer: If the tile is not in place, and you can afford to break a tile or two, you can always try drilling with a masonry bit. But if the tile is already in place, you really don’t want to break a tile. So:
Diamond or Tungsten Carbide Bit
These specialty bits have certain materials on the tip which help grind through the tile with less pressure. Note that you’re not actually drilling a hole. It’s more like a slow, grinding process where you methodically chip away at the tile.
Diamond Hole Saw
Bits are good for holes up to half an inch. For wide holes, you’ll want a diamond hole saw. It’s a pricey item but about the only way to carve a wide hole.
Tile Drilling: Special Note
Do not "hurry up" your tile-drilling. Slow is the key here. As noted, you are basically chipping away friable material. Also, water from a spray bottle cools down the bit and keeps dust down.
