Ordinary glazed tiles can be hammer or dual-use drill with the impact drill,
The tiles should be fitted with hand drill with glass drill.
We generally use a small sandblasting bit on the market can buy a good use
Agree with the advice of the experts upstairs, but I personally may choose to use nails to gently damage the surface of the tile, so the use of impact drill or drill bit, relatively speaking, the accuracy will be relatively high, but also for the surrounding tile damage will Corresponding small ones
