It needs some specific skills and caution to drill a hole in the mirror without breaking it. Here we will provide a step-by-step guide on drilling a hole in a mirror with a glass drill bit. After finishing the article, you will be able to drill a hole in a mirror with a glass drill bit safely and, of course, without breaking it.
How To Drill Holes In Mirror With Glass Drill Bits – Choose The Right Glass Drill Bit
Drilling a hole in the mirror is not like drilling into wood. It would be best if you choose the right bit to drill a hole in a mirror. You will need the right tool in your hand. If You follow the correct technique, then creating a hole is in a mirror is not that tough.
As glass is brittle material so you will have to pick a sharp, tricky drill bit to drill a hole into that. Don’t apply excessive force either, as that can break the mirror. You have to adjust the drill to a lower level. Please don’t go for cheap bits as they won’t last long and definitely harm your mirror.
You can choose between two types of bits for drilling holes in a glass: the tungsten carbide-tipped drill bit and the diamond drill bit. Carbide-tipped drill bits are used for non-tempered glass, ceramics, tiles, etc. But for tempered glass, the mirror diamond drill bit works better. A diamond drill bit creates holes from one-fourth inch to larger. It creates smoother holes. The diamond drill bit is specially made for drilling a hole in a glass.
You can dry with regular drill bits, but you have to be a superman to achieve that.

How To Drill Holes In Mirror With Glass Drill Bits – Mark the Hole Location
- Determine the location: Decide where you want the hole to be on the mirror. Measure the distance from the edge of the mirror to the center of the hole and mark the spot with a marker or painter’s tape.
- Use a level: Use a level to ensure that the mark is straight and even. This is especially important if you are drilling multiple holes and want them to be aligned.
- Double-check the location: Before drilling, double-check the location of the hole to ensure it is where you want it to be. Make any necessary adjustments to the mark if needed.
- Use painter’s tape: Apply a small piece of painter’s tape over the mark. This will help prevent the mirror from cracking or chipping while drilling.
Prepare the Mirror Before drilling
Preparing the mirror before drilling is a crucial step to ensure that the mirror does not crack or shatter during the drilling process. Here are some steps to follow when preparing the mirror:
- Clean the area: Use a glass cleaner and a lint-free cloth to clean the area where you will be drilling. This will remove any dirt, dust, or smudges that could interfere with the drilling process.
- Cover the area: Apply a piece of painter’s tape to the mirror to cover the area where you will be drilling. This will help prevent the mirror from cracking or chipping while you drill.
- Spray water: Spray the area where you will be drilling with water. This will help cool down the drill bit and lubricate the area, making it easier to drill into the mirror.
- Position the drill: Hold the drill perpendicular to the mirror surface. This will help ensure the hole is drilled straight and does not damage the surrounding area.
Start Drilling a Hole in Glass With a diamond drill bit
We assume that you have taken the proper safety measures. And you also have brought the correct glass drill bit and diamond drill bit. Now you can make your hands dirty.
Important: Before you start, you must use painter’s tape to attach the mirror to the board. Mirrors are slippy materials and can sleep while you have started drilling holes in the glass with a glass drill bit. So, use the tape and attach the mirror firmly to the board.
Step 1 – Use the permanent marker to mark the location where you want to drill a hole in the glass.
Step 2 – Put the diamond drill bit in the drill. It would be best if you started with a smaller diamond drill bit. If you plan to create a giant hole, don’t worry, as you can enlarge the hole with a significant drill bit later.
Step 3– Wear your safety glass to protect your eyes from any unnecessary accidents. Don’t forget to wear gloves also.
Step 4 – Put the mirror on a flat and solid surface(A table would be best). You must attach the mirror perfectly to the board. Use the cushion to adjust it firmly.
Step 5 – Power up the drilling machine. For this kind of hole, it is better to hold the drill at a 45-degree angle. Do not hurry to put the hole and never panic. It would be best if you never put extra pressure like that that can break the glass. Let the drill to the job, not your force.
Step 6 – When you feel you have created a primary hole in the mirror, it’s time to go to the next phase. Hold your drill at a 90-degree position and continue drilling.
Step 7 – You should use water or other lubricants that you have brought to complete the job. This will protect the glass from heating. Overheating can break the glass, so keep using water.
Step 8 – Don’t get over-excited. You should know the thickness of the glass mirror and how deep you want to make that hole. It should take 4 to 5 minutes for a standard mirror. For a thicker glass mirror, you should drill for 5-10 minutes.
Important: For inside-out holes, drill from both sides. Do not try to drill from one side; that can break the mirror glass.
Cleaning Up After drilling a Hole in the Glass Mirror
After drilling the hole in the mirror, it’s important to clean up the area to ensure that there is no debris or residue left on the mirror surface. Here are some steps to follow when cleaning up after drilling:
- Remove the painter’s tape: Gently remove the painter’s tape from the mirror surface.
- Clean the area: Use a glass cleaner and a clean, lint-free cloth to clean the area where you drilled the hole. This will remove any debris, residue, or fingerprints left on the mirror surface.
- Remove debris from the hole: Use a soft-bristled brush or a cotton swab to remove any debris that may be stuck in the hole.
- Inspect the mirror: Carefully inspect the mirror to ensure that there are no cracks, chips, or scratches that may have occurred during the drilling process.
Cautions While Drilling A Hole In Glass Mirror
We have learned how to drill holes in a glass mirror. But some amateurs can break the glass while drilling. Glass mirrors are brittle materials, so you have to be patient and use the proper drilling techniques when you are drilling a hole in a mirror with a glass drill bit.
DO NOT use an old bit. You should start with a new drill bit. We suggested a diamond drill bit. But like any other glass drill bit, the diamond bit also gets dull. So we strongly recommend that you use a fresh bit. If you use a dull bit, then the glass mirror can shatter, and the glass mirror will break down.
Support the glass mirror at all times while drilling. The glass should be on a plain and flat surface. If the surface is not plain enough, your glass mirror will break for sure. It would help if you produced appropriate support.
Drill gently and slowly. Remember, it is a delicate drilling application, and you have to be patient. Drilling a hole in the glass mirror is not the kind of work that you can do in a rush. It is recommended to start with 1/8” or 3/32 in size to create a dimple in the glass. You also should begin with a 45-degree angle and then go with a 90-degree angle. Don’t start drilling vertically from the beginning; you will break the glass for sure.
Always start with the small hole and use a tiny size bit. Do not worry about the finished hole at the beginning. You should begin with a bit of a hole at first. As we stated, early start with a small diamond drill bit like 1/8” or 3/32 in size. Create a dimple first, and after you create the hole, you can change the drill bit and go for a giant hole with a more significant bit.
Ensure that the glass mirror does not catch high temperatures: The glass mirror will surely heat up while you are drilling. You must be conscious of the scenario or end up with a broken glass mirror. Control the temperature with water or another lubricant that you brought and use that material frequently.
DO NOT drill near the edges of the glass mirror. Experts say that you should keep at least ¾ inches distance from the borders of the glass mirror. You can not get sufficient support if you drill near the border. So, there is a high chance that the glass mirror will break into pieces. Do not drill through the near border.
Clean the surroundings with the towel properly. Do not remove your gloves before you clean the area properly. Tiny pieces of glasses are hazardous, and they can hurt you severely.
