Glass Cutters: 11 Facts You Should Know (Explained)

If you’re looking for a new hobby, or just an interesting way to spend your time, then there is no better option than glass cutting. You can create beautiful pieces of art and enjoy the process as well.

But before you go out and buy any tools, it’s important that you know some facts first. Here are 11 things that everyone should know about this hobby.

1. How Do I Choose a Glass Cutter?

It is extremely important for the glass cutter to fit your hand properly. Your grip on the tool should not be too weak or strong; try different types of cutters until you find one that works well for you.

A good cutter has a handle with grooves that fits comfortably in your hand, and provides balance while using it. Glass cutters are also available in different sizes, so it is important to choose one which fits your hand. The size of the wheel will vary depending on the glass cutter being used.

A larger wheel works better when cutting large pieces of glass, while a more compact wheel is ideal for cutting small pieces of glass.

2. How Do I Cut Glass With a Glass Cutter?

Use the glass cutter to make a small cut along with the glass bottle. It should look like you are making hash marks on the edge of the glass. Use the glass cutter to make a small score (cut) line around your glass piece by holding it in place and rotating it until you have gone completely around the perimeter of the piece.

Press down on one side of your score line, and push it gently towards the other side of the score line with a slight twisting motion while applying pressure. This will allow the score line to deepen, making it easier to break.

Once you have gone around the entire edge of the glass again with a slight twisting motion, press down firmly along the score line and snap off the glass.

3. How Do I Fix Mistakes When Cutting Glass?

If you cut through your score line, it is possible for you to fix the mistake. Using a glass cutter, make another score line next to the first one. Once they meet, apply pressure and break off any excess glass as described above.

This process can be repeated multiple times until you have removed all of the broken pieces from your score line.

Hint: Make your first score line very light, and your second score line heavier. This will make it easier to cut through the first line again if you need to remove any mistakes.

4. How Do You Cut Glass Cleanly?

When you are cutting a straight line, it is important to apply light pressure on the glass cutter. If you push too hard, you will end up cracking the glass. At this point, after applying small pressure while moving the cutter in a smooth motion across your piece of glass, slightly increase the pressure and move faster. Just remember more pressure equals a cleaner cut.

Make sure to keep the wheel along the edge of your piece of glass and move in one fluid motion without stopping or pausing. If you stop while cutting, this increases the risk of cracking your piece of glass.

If you are having difficulty making a clean cut when using a glass cutter, try drawing an initial line onto your piece of glass with a pencil before cutting. The lines will serve as guidelines so you can cut your glass with ease.

5. What Types of Glass Require Different Cutters?

Cutting thick glass usually requires using a heavy-duty cutter with a large wheel for increased stability and more pressure. Also, depending on the type of glass you’re cutting, a more suitable cutter will need to be used.

Tempered glass and laminated safety glass cannot be cut with the same tools as regular window glass. They require very specific cutters in order to avoid damage or injury while cutting.

6. What Other Tools Can I Use to Cut Glass?

Angle grinders can be used to cut through thick pieces of glass. Angle grinders are often difficult to control and can cause serious injury if mishandled. It is important to use safety equipment when using an angle grinder, including protective eye gear, gloves, and a breathing mask.

A Dremel-type tool with a diamond wheel can be used to cut glass. The smaller the wheel, the more detailed the cutting. However, using this method is not recommended for beginners as it presents several risks including the danger of injury from shards of flying glass.

Other tools for cutting glass can include normal saws, but these tools are much more dangerous to operate, and the cuts will not be as clean.

7. What Kind of Blade Do You Need to Cut Glass?

The cutting wheel on glass cutters can be made of either tungsten carbide or diamond. The blade will wear down over time, therefore it’s important to keep extra blades around so that one is always sharp.

Tungsten carbide glass cutter blades are made for both manual glass cutters and glass breakers. They are used for cutting glass, tile, sheet metal and other thin materials.

8. How Thick of Glass Can You Cut With a Glass Cutter?

Glass cutters can generally handle glass up to 0.5 inches (13 mm) thick, but it is advisable to use a thicker wheel if you are cutting through thicker types of glass.

9. Can a Tile Cutter Cut Glass?

Yes, a tile cutter can cut glass. However, you will need to adapt the way in which you use the tool. While a glass cutter cuts along the surface of a piece of glass, a tile cutter uses pressure to break the glass.

This means that you should not push too hard on the blade when cutting glass with a tile cutter. If you do, the blade may slip and cause injury.

10. What is a “Score Line”?

A score line is a thin line created in the process of cutting through glass. The score line allows the glass piece to be split into two halves along the score line.

11. How Hard is it to Cut Glass?

An incorrectly cut glass piece can be irreparable . Even with the proper tools, cutting glass can be difficult. It is important to have steady hands while using a glass cutter. Otherwise, the blade will slip and you could either cut yourself or damage your piece of glass.


When you’re looking for a new hobby or an interesting way to spend your time, glass cutting is one of the best options. Not only will it give you the opportunity to create beautiful pieces of art that are unique and personal, but it also gives you something fun to do in your free time.
