How do you drill a hole in ceramic without breaking it?
Do you need a special drill bit for ceramic? A drill bit used for wood or metal is not going to do much to drill into ceramic tile. You need a special drill bit that’s got a carbide tip. It’s important to realize not all ceramic tile is the same. It comes in a wide range of hardness.
What kind of drill bit do you use for ceramic? Ceramic tile can be drilled with a carbide bit, while glass and porcelain call for a diamond-tipped bit. While that sounds expensive, a ¼ inch diamond tipped tip costs under $20, and a carbide bit of the same size can be had for less than $10. When in doubt, buy the diamond bit. It will drill any type of tile.
Should I use water when drilling ceramic? first, in order to keep the drill bit from slipping off the mark, put a few layers of masking tape over the ceramic before drilling. Second, water can act as a lubricant and can also help keep the drill bit a little cooler, though very thin glazes really don’t need the extra lubricant.
