As you continue drilling, keep the drill bit lubricated by periodically spraying it with water from the spray bottle. This will help cool down the drill bit and prevent the glass from overheating, which can lead to cracking or shattering. Gradually increase the drill speed as you go, applying gentle and even pressure. Take breaks if needed to prevent the glass and drill bit from getting too hot.
Once you’ve drilled through the glass, slow down the drill speed and remove the drill bit. Be careful not to rush this step, as pulling the drill out too quickly can cause the glass to crack. Gently lower the drill speed and extract the bit from the hole. Inspect the hole to ensure it’s the desired size and shape. If necessary, use sandpaper or a diamond file to smooth any rough edges.
And there you have it! With a little patience and the right tools, drilling a hole through glass can be a straightforward process. Now you can confidently tackle glass drilling projects and create beautiful and unique pieces for your home or as gifts.
