Ceramic tiles that are installed in a kitchen or bathroom may need to have holes cut out for plumbing and accessories such as a towel rack. One way to make a hole in ceramic tile is to use a power drill with a carbide drill bit. Making a larger hole typically requires the use of a specialised attachment for the drill. However, you can easily cut a larger diameter hole out of ceramic tile by just using the single bit on a power drill.
Draw a hole on the tile that needs to be cut, with a felt-tip marker.
Drill holes within the circle, along the inside of the line you drew, using a power drill with a masonry drill bit. Make sure the holes are closely spaced together within the circle.
Tap on the tile, within the circle of holes, lightly with a hammer. The centre of the hole should break away within a minute or two of gentle tapping.
Dull the edges of the hole using a tile file.
Mark the tile where the hole needs to be cut, with a felt-tip marker.
Insert a carbide-tipped hole saw attachment into the power drill.
Place the hole saw attachment over the mark on the tile.
Press the trigger on the saw to begin slowly cutting through the tile.
Maintain pressure on the power drill until the hole saw attachment has completely cut through the tile.
Drilling holes and tapping with a hammer can also be used to cut out square and rectangular shaped holes in ceramic tile.
Tapping on the tile needs to be a slow and patient process, or the tile will crack.
