In this article, you will read about how to drill a hole in a glass by using regular drills and specific drill bits. Drilling a hole through glass can be complicated if the right drill bit is not used, you can use regular drilling tools to drill through glass, but you cannot use standard drill bits.
The key is to use something more challenging than glass to get through the glass. We have researched and listed below the tools, bits, and guides to make drilling through glass easy for you. So how to drill a hole in the glass?
Things You Should Know
1. Know Your Glass
The first thing you should do before actually drilling into a glass is to know the kind of glass you’re drilling through.
You can drill through all kinds of glass except tempered glass or safety glass; the reason for this is because tempered glass, no matter what tool you use, and no matter the bit size or kind, it will break or get shattered when drilled through. So never drill through tempered or safety glass.
2. How To Know If The Glass Is Tempered?
Tempered glasses, unlike regular glass goes through extra processing, which is why it needs to be sandblasted, so look thoroughly at the edges of the glass, tempered glasses have smooth, even edges because of the process that it goes through.
You don’t need special tools to drill through the glass special tools to drill through the glass. You can use a drilling tool that you already have, or you can buy any standard power drill; this also helps you, achiever, your target, or complete your work.
2. Drill Bit
The kind of drill tool is not essential, but the drill bit is significant; there are individual drill bits that are perfect for drilling through the glass. You should only use those bits to achieve the results you want.
Glass drill bits are available both online and at local hardware stores to easily avail it.
The bits you should use are:
- Carbide-tipped bits: this bit is made to drill through glass, tiles, and ceramic; the tip of the bit is spade-shaped and made of hard tungsten carbide. This bit is durable and can withstand the friction caused when drilling through glass. See the comparison of different drill bits.
- Diamond-tipped drill bits: these drill bits can drill through glass and other hard materials like stone, marble. If these bits are appropriately used, they do not cause any breakage.
3. Marking The Portion Before Drilling
Another key point always marks the area you want to drill, be it in a specific shape or something random this will give you a clear picture before making the drill and help you avoid making mistakes. You can use a marker to mark the glass, or you can even use hot glue, hot glue once dried, easily comes right of once it is cooled down, and it does not leave marks.
How To Drill A Hole In The Glass – Step By Step Process
- Before drilling first, you must ensure that the glass is placed on a table or any surface that you wouldn’t mind if you accidentally drill through it; if you want to drill through a glass bottle, then place it in a container before drilling.
- Cover the portion you want to drill through with a piece of cardboard or tape and start drilling at a very low speed; once you drill through the cardboard and make a dimple in the glass, then you can remove the cardboard and continue drilling through the glass.
- Make sure the glass is supported. This will help you make a clean and smooth drill.
- When your drilling through hard materials like glass, always adds light pressure on the drill. If you add too much pressure, the glass can break or shatter.
- Always start by creating a dimple in the glass before going into full drilling mode.
- You can start by using a bit size of 1/8inch or 3/32 inch.
- Start slow, and then you can go a little bit faster around 400RMP.
- When you reach the finishing point, slow down your pressure and the drill speed even more so that you prevent the glass from chipping.
- The drill can get hot while using it, which is why it Is advised to use a coolant; you can use oil or water as coolants.
How To Use The Coolant
- A coolant is a substance in liquid or gas form and is usually used to keep heat away from materials.
- You can use oil or water as coolants when your drilling through glass.
- Pour a little on your drilling; this will keep the glass and the drill bit cool.
- The reason is if the glass gets too hot, which can happen from the drilling machines heat, it can break, so to avoid this, you should use a coolant.
- Apply the coolant before and during the drilling process
- Electric cords and water do not go well together. Remember that when you are using water: a tip, you can put the water in a spray bottle and spray it for safety precautions.
- You can also use a sponge. Just wet it and keep dabbing the glass with it this way, it remains cool.
- The harder the material, the more coolant you should use.
Things You Need To Drill Into The Glass
- Appropriate drill bit: use a Carbide-tipped bit or Diamond-tipped drill bit.
- Any power drill tool with spare bits.
- Coolant: this can be water, oil, or sponge filled with water.
- A surface to place your glass.
- Protective gear like glasses and gloves: this is advised because small glass particles can enter your eyes while dangerous drilling; hence you should wear protective gear.
- Cardboard or tape: use this when your drilling, first add a piece of tape or cardboard on the area of glass that you want to drill, make a dimple and then after that, you can remove it and continue.
There are two kinds of tools you can use to drill through a glass are:
- A Hand drill.
- A Drill press.
You can either use a hand drill or a drill press to drill through the glass.
A Drill Press is always the easier and safer option, it is cheap, you can set the speed as per your convenience, and a Drill Press is like a stand so you won’t have to hold the glass while drilling through it.
A Hand Drill, on the other hand, is also easy to use, but it takes a lot more effort than a Drill Press since this is a Hand Drill, you need to hold the drilling tool to drill.
1. What kind of drill bit to use to drill a small hole in a glass?
To drill small holes in the glass, you should use a diamond bit; you can use a titanium one, but the diamond one will give you better results.
2. Can I drill through tampered glass?
No, you cannot; the tampered glass will immediately break or shatter when drilled through.
3. What is the easiest way to drill through glass without breaking it?
The easiest way is to add a piece of tape or cardboard on the surface that you want to drill and then drill slow; once you make a dimple, you can remove the tape or cardboard and drill. The key is to maintain low to medium speed and pressure.
4. What is the best bit to use to drill through glass?
The drill bits that are made to drill through the glass are:
Carbide-tipped bits: this bit is made to drill through glass, tiles, and ceramic; the tip of the bit is spade-shaped and made of hard tungsten carbide.
This bit is durable and can withstand the friction caused when drilling through glass.
Diamond-tipped drill bits: these drill bits can drill through glass and other hard materials like stone, marble. If these bits are correctly used, they do not cause any breakage.
There are also diamond-coated drill bits too.
The main thing that one needs to keep in mind before drilling a hole through glass is knowing the type of glass your using and following the right steps to make a clean and suitable cut.
Another critical point is always to mark the area you want to drill; this will help you avoid making mistakes. Drilling a hole through a mirror or a pane of glass is simple. You can use a carbide bit to get your work done, as this bit is specially designed to drill through the glass. Make sure that you are aware of the right technique that is required before drilling because this is glass, and using the wrong amount of pressure and speed can shatter the glass, an improper technique which will lead to a huge waste of time, energy, and effort.
