The next thing to consider is the coating. The coating enhances the lifespan of the bits while preventing damaging the tile. Expert plumbers and handymen recommend a titanium coating, as it is long-lasting and heat-resistant.


The choice of shank type depends on your personal preference. However, there are some shank types, such as hex, that are compatible with all types of power tools.


Always consider the bit’s size when buying one for drilling through porcelain tiles. I recommend buying sets, as you get several bits to drill holes of varying sizes. 

Tips to Drill Through Porcelain Tiles: Don’t Break It!

Even with the best drill bits in hand, drilling through porcelain tiles can be slightly challenging. Here are some tips that’ll ease the job and minimize the risk of damaging the tiles.

Start Slow 

When drilling through porcelain tiles, you should keep the drill at the lowest RPM. It will help you understand how the bit performs. Now gradually increase the speed and drill the hole properly.

Use a Lubricant 

A lubricant reduces friction and protects the bit from damage. You can even use water to ensure the drill bit works perfectly on the tile.

Adjust Speed

Keep adjusting the speed of the drill depending on the bit size and type. If you are using a thicker bit, you should drill at slow RPM, and thinner bits can drill at faster speeds. 

Cool the Drill 

After drilling a few holes, you should let the drill cool down, or else it’ll snap since porcelain tiles are tough. Don’t pour water on the drill, but let it cool naturally.
