While carbide-tipped bits are more popular for drilling a hole into tiles, it’s actually the core bits that are more durable. For harder materials especially, a diamond core bit is certainly the better choice.

When you’re done installing your tiled wall and ready to put accents and fixings, you’ll need to drill a hole. But in doing so, there is always the danger of cracking or breaking the smooth tile. To avoid unwanted things from happening, here’s the proper way to do it:

Prepare the surface

What makes drilling through tile difficult is the tile’s outer surface, which generally resists drilling. In other words, the start is always most difficult as the bit won’t readily bite because of the glazed surface, causing it to wander and slip. For this you will need masking tape, a pencil, and perhaps a spirit level for that perfect line. The masking tape will provide the traction. Measure before and after you apply the tape to be sure the hole is not misplaced. Measure twice and drill once, remember that.

Break in and follow through

Get a good hold of the drill. Slowly and carefully, start drilling at a low speed and gradually get faster if need be.  The pressure you put into it should be hard enough to bore through but not so much that it gets the tile to break. By then it should be smooth drilling for you. It can be tempting to go fast and hard, so think about what could happen if you feel the urge. Remember to keep the tip of the bit lubricated to prevent overheating. A little patience and a helping hand should make the job a lot easier especially during this stage.


That’s it, you’re done with your first hole. As to how many more you need to drill, it all depends on your purpose; and when you’re done you should be able to put your desired accents and fixings.

In drilling a hole, the first part is quite risky, but after that, things will get smooth if you apply the right pressure and display enough patience. If you have any questions, please feel free to contact us and browse through our website.
