What bit to drill through ceramic tile?
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.
