From diamond-tipped to carbide-tipped bits, there are plenty of options available to get the job done – all under the $20 mark! Read on for the best drill bit for bathroom ceramic tile, and learn how to drill through glazed or unglazed terracotta or clay pots. Keep your bathroom looking fresh and fabulous!

How to Drill into Ceramic and Clay Pots

Drilling a ceramic pot requires the use of a specialized drill bit, known as a diamond drill bit or masonry drill bit. This type of drill bit is similar to using a wet saw when drilling into tile, and can be obtained relatively inexpensively in packs of five online or at hardware stores.

It is important to start with a slow speed and gradually increase it when drilling into ceramic. If you go too fast, the ceramic can crack.

For bathroom ceramic tile, the best drill bit is a carbide-tipped masonry bit. Regular twist-drill bits will not be able to cut through the fire-hardened glaze of ceramic tiles.

When drilling, it is important to set the drill to between 1000 and 1500rpm if the drill is in normal mode. It is also beneficial to mark the tile with a marker before beginning, as this will help you remain centered as you drill into it. “Leaning in” ensures that the drill won’t wander off center as you drill into the tile.

For unglazed terracotta or clay pots, a masonry bit can be used. Masonry bits are common in most drill bit sets, so it is important to check if you have them before buying a specialized diamond drill bit.

Drilling into Ceramics: The Proper Tools and Techniques

When drilling into other types of ceramic, such as glass or porcelain, it is important to use a diamond-tipped drill bit. Although this may sound expensive, diamond-tipped bits are available for under $20 and can be purchased online or at hardware stores. Additionally, carbide bits that can be used to drill ceramic tile are available for under $10. It is important to start with a slow speed and gradually increase it when drilling into ceramic material; if the drill goes too fast, the ceramic can crack.


In conclusion, it is important to have the right drill bit for the job. For glass and porcelain, a diamond-tipped bit is needed, while ceramic tile requires a carbide bit. Unglazed terracotta or clay pots require a masonry bit. Finally, for ceramic pots, a diamond drill bit or masonry bit is necessary. With the right drill bit, you can have the desired results in no time.
