How to Drill a Hole in Glass

Drilling a hole in glass can be a daunting task. It requires precise steps and the correct tools to ensure that your glass is not damaged in the process. Learn how to drill a hole in glass with the help of this guide.

What You’ll Need

The tools you’ll need for this project include a drill, a glass drill bit, a glass saw, and some lubricant.

1. Start by drilling a hole in the glass using your drill. Make sure to use a correct bit for the drill; some bits are designed specifically for drilling through glass. Check the manufacturer’s website or product packaging for information on the right bit for your specific model of drill.

2. Insert the glass drill bit into the drilled hole and use your saw to make the final cut. Be careful not to apply too much pressure when cutting; over-cutting can cause damage to your glasswork.

3. Apply a layer of lubricant to the blade of your saw before cutting; this will make the process easier and reduce the risk of injury.

4. Once you’ve made all the cuts you need, remove the drill bit from the glass and clean up any messes made during construction.

Tips for Making the Hole Easier to Saw

When drilling a hole in glass, it is important to make the process as easy as possible for the saw. Any bumps or ridges on the inside of the glass can cause the drill bit to catch and slow down the drilling process, leading to frustration on your part and a potential mess.

To avoid this issue, use a drill bit that is specifically designed for drilling through glass. This type of bit has sharp edges that will easily cut through the glass without causing any damage. Additionally, be sure to hold the drill firmly against the glass while drilling, and use a light touch when pulling the drill bit out so as not to create any sharp edges.

If you find that your drill bit is getting stuck or causing too much friction, it may be necessary to replace it with a different one. To do this, remove the bit from the hole using a screwdriver and place it in a bowl of hot water. Once it has cooled down, replace it with the new bit and gently try to push it back into the hole. If all goes well, you can now reattach the drill to your power tool and continue drilling as normal.


If you regularly need to drill a hole in glass, or if you want to make an ornament out of glass, this tutorial will show you how to do it without damaging the surface. The process is simple and can be completed with just a few household items. Be sure to read through the entire tutorial before beginning so that you understand all of the steps involved.
