How to Cut Tempered Glass Safely and Effectively
You may have wondered how to cut tempered glass, whether you work with glass, are an experienced contractor, or are simply doing a home project yourself. It’s a good question, particularly because it seems simple to score and break regular glass. But tempered glass has its own limitations. In this post, we’ll talk about how hard it is to cut it, what your alternatives are, and how to do it safely if you really need a custom cut.
Understanding Tempered Glass
Tempered glass is very durable, can withstand heat, and won’t break, which is why it’s a popular option for doors, windows, shower doors, commercial setups, and many more. It helps to know what makes tempered glass so special before we learn how to work with it.
What Is Tempered Glass?
Tempered glass is a sort of safety glass that is made using a special method to make it stronger and tougher. It is heated to extremely high temperatures and then cooled rapidly. This makes tempered glass significantly stronger than conventional glass because it puts pressure on the inside. Its key characteristic is that glass breaks into little, dull bits instead of sharp shards, which makes it safer for homes and public places. Many people ask, is there a way to cut tempered glass — and while the short answer is “not really,” understanding how it’s made helps explain why.
Why Is It Difficult to Cut?
It’s really hard to cut tempered glass, and for good reason. If you try to cut or drill it at home, it will most likely break right away because of how it is created. The tension within it that makes it strong also makes it very easy to break. If you try to cut it, the balance of tension will be thrown off, and the entire piece will break right away.
Safety Precautions Before Cutting
As you’ve already understood, how to cut tempered glass is not an easy question. If you still have to accept this challenge, safety should always come first.
When tempered glass breaks, it does so suddenly, literally bursting with great force, and sending small pieces of glass flying in all directions. So, before you approach it, make sure you are completely safe. Put on thick gloves, long sleeves, safety goggles, and, if you have it, a face shield. Keep all other people away from the working area and work in a clean, open space. It’s important to handle tempered glass securely, even if you’re not the one cutting it.
Tools Required for Cutting Tempered Glass
To be perfectly honest, there is no safe or sure technique to cut this glass once it has been tempered. Some sources claim that diamond blades would work, but that’s not true. People often wonder, can tempered glass be cut with specialized tools — but even with them, the cutting process nearly always ends up breaking because of the tension that builds up within the glass during the tempering process. Industrial settings use the following equipment.
High-temperature annealing furnaces
Used to undo the tempering process before cutting. This process is quite hazardous and is not always guaranteed to be successful.
Laser or water jet cutters
Sometimes used on some kinds of glass before they are completely tempered, although not very often
Vacuum table or containment setup
To keep the area safe if the glass breaks
It’s better not to do this at all if you’re not working in a professional shop with the necessary equipment and space. Is it possible to cut tempered glass yourself? The best solution would be to order tempered glass already cut to size. It’s safer, cheaper, and a lot much handier.
Step-by-Step Guide to Cutting Tempered Glass
You should remember that you can’t cut tempered glass once it has been heated. However, if you have raw glass (not tempered) and want to cut it beforehand, this is the usual procedure.
Measuring and Marking the Glass
First, measure the precise size you need very carefully. After using a ruler or measuring tape, use a grease pencil or permanent marker to mark the glass. The score line might be ruined by any tilt or dirt, so be sure your surface is flat and clean. If you’re working with raw glass and learning how to cut tempered glass the right way (before the tempering process), accurate measuring is the first and most important step.
Scoring the Glass Surface
Make a single, smooth score along the indicated line using a high-quality glass cutter, ideally one that has an oil reservoir. Apply even, hard pressure; a steady scraping sound should be audible. Avoid crossing the same line twice, as this may cause surface damage and an uneven break.
Breaking the Glass Along the Score Line
After that, gently push down on both sides of a short dowel or matchstick that is placed under the scoring line. The glass should break smoothly along the line. For more control, you may also employ special breaking pliers.
Smoothing the Edges
The edges of freshly cut glass may be jagged or sharp. To smooth them out, use a diamond pad or fine-grit sanding stone. As microscopic glass particles may be harmful, always wear gloves and goggles when performing this procedure.
Fixed Panels / Walk-In Screens
Fixed glass panels, also known as walk-in screens, create an open bathroom area without any moving parts. Typically, they are employed in contemporary, minimalist settings where a clean layout and easy access are essential. There isn’t a door to open or shut, so upkeep is easy, and the area seems more open. Depending on how much privacy and style you want, this layout works perfectly with many different shower door glass options, such as clear, tinted, or frosted glass.
Common Mistakes to Avoid
You need to be patient while working with glass, because tempered glass doesn’t give much space for mistakes. It’s crucial to avoid these following mistakes when you learn how to cut tempered glass, as they can rapidly make a project a disaster or potentially a danger.
Applying Excessive Pressure
One of the most common myths is that pushing harder can help you achieve your goal faster. In fact, putting too much pressure on anything might break the surface or cause tension to be uneven, particularly on glass. The scoring should be forceful yet smooth. Let the cutter do its job. Keep in mind that attempting to cut tempered glass will most likely cause it to break completely.
Inadequate Safety Measures
Even though tempered glass is made to shatter into small, dull bits, that doesn’t mean it’s 100% safe. There are still shards flying around, and you can be harmed. ADon’t forget to wear long sleeves, gloves, and eyewear to protect yourself. These are your first line of protection. People often ask, can tempered glass be cut with power tools or industrial equipment like kilns or jet cutters. The answer is: only under highly controlled conditions. If you’re using such tools, be sure you know how to use them and are working in a safe place.

Alternatives to Cutting Tempered Glass
After tempered glass has been treated, cutting it isn’t really a choice. Instead, you should seek safer and more effective options.
Consulting Professionals
Consult a glass expert or supplier if you require a specific size or are working on a unique project. They can assist you in deciding whether cutting is even needed and, if it is, how to do it safely before tempering. Experts have access to industrial equipment and know how to operate with glass safely, without breaking it.
Ordering Pre-Cut Tempered Glass
So, what is the best way to cut tempered glass and solve the problem? Purchase your tempered glass already cut to the proper size. Most producers allow you to cut things to size before tempering, so you get precisely what you need without the risk of cracks or breakage. It may require a little more forethought and additional expenses, but it saves time, tools, and stress in the long run. You’ll also know that your glass was cut securely and properly, so you can install it as soon as it arrives.
