Cutting Bricks With An Angle Grinder Step By Step

So, you want to learn how to cut bricks with an angle grinder? Well, let me tell you, it’s not as difficult as it may seem.

Down here we will discuss the steps to follow. But first, make sure you have all your necessary equipment ready before starting.

You’ll need:

  • An angle grinder with a diamond masonry blade (or circular saw),

  • dust mask, and appropriate safety gear such as gloves and eye protection.

  • Chalk, Pencil or Chisel

  • Measuring tape

1. Taking Measurements

Let’s dive into taking measurements. This is an important step to ensure that your brick cuts are precise and straight.

Before you start cutting, it’s essential to measure the length and width of the brick accurately. To take measurements, use a measuring tape or ruler to mark out where you want to cut on the brick. Make sure your lines are straight and even you can use a masonry chisel to score along them lightly. But more on that later.

2. Take Safety Precautions

Before we dive into the nitty-gritty of cutting bricks with an angle grinder, let’s talk safety. Using a power tool when cutting brick can be extremely dangerous.

First things first: protective gear is a must! Wear earplugs or noise-canceling headphones to protect your hearing from the loud grinding noise. Also, wear goggles or safety glasses to shield your eyes from flying debris and dust particles. And speaking of dust – it’s important to wear a respirator mask as well, especially if you’re cutting through a lot of brick.

Now that you’ve got all your protective gear on, let’s move on to some other safety precautions. Always ensure your angle grinder is unplugged before changing blades or making any adjustments. Keep both hands on the tool at all times while it’s running and never try to force it through tough spots – this can cause kickback and be dangerous for you and anyone else nearby.

If possible, use a vice grip or clamp to secure the brick while cutting so it doesn’t shift around unexpectedly. Lastly, consider using a brick chisel instead of an angle grinder if you only need to chip away some stone – this may be safer and more efficient depending on the project at hand.

3. Choose The Right Tool And Quality Discs

Now that you know the basics of cutting bricks with an angle grinder, it’s time to choose the right tool and quality discs. This is a crucial step in ensuring your safety and achieving accurate cuts on your brickwork project.


Firstly, I recommend using a portable angle grinder – this power tool will give you more control over the cut than using a mason’s hammer or chisel.

A 4,5 inch is common in many households, however you won’t be able to cut as deep as a 9 inch diameter blade. So thinking about the depth of the cut and thickness of the brick is important.


Secondly, invest in diamond blades instead of metal cutting discs as they last longer and are designed specifically for brick-cutting.

By choosing the right tools and using high-quality discs, you can ensure precise cuts and minimize any risks associated with cutting bricks with an angle grinder.

4. Mark Your Cut

Now that you have your angle grinder ready, it’s time to mark the bricks for cutting. This may seem like a simple step, but trust me when I say that taking your time and doing it right can make all the difference in the final outcome of your project.

Before you start marking anything, make sure that you have a stable surface to work on. You don’t want your brick moving around while you’re trying to cut it!

Once you’ve found a good spot, take out your pencil and carefully mark where you want to cut. Remember: measure twice, cut once! Try to make sure that you only need to pass through the brick once – this will help ensure a cleaner cut with less waste on the ‘waste side’.

If necessary, use a cold chisel to score along your pencil line before making the actual cut with your angle grinder. Take some deep breaths and make sure that you feel comfortable before starting – precision is key here!

Remember that every edge counts when working on any DIY home renovation projects.

5. Cutting Bricks With Angle Grinder, Tool and Workspace Preparations

  1. Choose a suitable workspace: It can be a messy job, so it’s important to choose an area that’s well-ventilated, such as a garage or outdoor space. Or if you’re working in an enclosed space, it’s important to have open windows, or use a fan to provide adequate ventilation. Make sure you have enough room to move around and set up your tools.

  2. Install the diamond cutting disc: Choose a diamond cutting disc that fits your angle grinder. The inches are usually stated on the disc. Follow the instructions provided by the manufacturer to install the disc securely onto your grinder.

  3. Make sure to use a full battery and have one or two fully charged at hand. Or when using a corded model ensure there plug is nearby and you cannot trip over the extension cord.

6. Cutting Bricks With Angle Grinders The Process

Now that you have your angle grinder ready, it is time to start cutting the bricks. To begin cutting, first, put on your goggles for safety purposes since this process can be extremely dangerous if not done correctly.

Then place the brick on a stable surface. And secure it with your hand, or feet but preferably, with some clamps

Begin cutting: Turn on the angle grinder and let it accelerate. When it reaches its highest RPM, you can lower it onto the marked area of the brick’s surface while applying gentle pressure. (Don’t press hard).

Finish off: Continue cutting through until you reach the end of the marked line then turn off the grinder and remove your goggles.

Remember that cuts made by an angle grinder are rougher than those made by a tile saw so always double-check measurements before making any cuts and take extra precautions when handling sharp edges after completing each cut.

With these tips in mind, you’re now ready to make precise cuts using an angle grinder!

Mistakes To Avoid

When cutting bricks with an angle grinder, there are certain mistakes you should avoid.

First and foremost, it’s important to use the best masonry blade for the job. Don’t skimp on quality when it comes to your cutting disc. You want something that is strong enough to cut through tough materials like brick, and one that won’t break down after only a few uses.

Another mistake many people make is buying the most expensive angle grinder because they think only expensive models can cut hard materials like brick.

Well I don’t agree, of course there is some truth in there, but most tools in the range of 50 – 100 suffice. It’s best to check the amp levels. The higher the Amp level, the stronger the motor and the easier it will cut bricks.

And finally, always remember to wear protective gear such as gloves and goggles to protect yourself from debris that may fly up during the cutting process.

By avoiding these common mistakes, you’ll be able to successfully cut bricks with an angle grinder without any issues!

Are Angle Grinders The Right Tool For Cutting Bricks?

An angle grinder can easily cut through bricks and other tough materials. But, it may not be the best option in all cases.

Firstly, if you’re a beginner DIY enthusiast or have limited experience using power tools, an angle grinder might not be the safest choice. The powerful motor and high-speed rotating disc can make it difficult to control on uneven surfaces, increasing the risk of injury or damaging your workpiece.

Additionally, while an angle grinder can handle most brick cutting tasks, there are some situations where another tool may be more suitable – such as when working with curved edges, intricate designs or hard to reach brick walls.

Ultimately, when deciding which tool to use for cutting bricks or any material, always prioritize safety and choose the method that will give you the best results without putting yourself at risk.

Alternatives Ways To Cut Brick

Now that we know how to cut bricks with an angle grinder, let’s explore some alternative ways of achieving the same result. While an angle grinder is a versatile tool for cutting different materials, it may not always be the best option for brick-cutting purposes. Thankfully, there are other tools and methods available to us.

One such method involves using a circular saw equipped with a diamond blade. This approach cuts brick easily but you need to be aware of the cutting depth. And, it is not maneuverable like the grinder.

Another option would be using a wet tile saw or masonry saw which can also handle brick-cutting tasks efficiently.

If you’re looking for something more straightforward, then opting for a chisel and hammer could work just as well too!

Frequently Asked Questions

Can I Use A Regular Disc On My Angle Grinder To Cut Bricks?

No, it is not recommended to use a regular metal cutting disc on your angle grinder to cut bricks. Metal cutting discs are designed to cut through metal, and using them on bricks can cause the disc to wear down quickly or even break, which can be dangerous.

Instead, you should use a specialized masonry cutting disc or diamond blade that is designed to cut through bricks and other masonry materials. These discs are made with a harder abrasive material that can withstand the toughness of the bricks without breaking down quickly. They also have a different shape and design that allows for better cutting performance on masonry materials.

How Do I Know If My Angle Grinder Is Powerful Enough To Cut Through Bricks?

First of all, take a look at the power rating on your tool – anything over 900 watts should be more than sufficient. Also, consider the size and quality of the grinding disc you’ll be using. I recommend the 4,5 inch DeWalt diamond masonry blade
With these things in mind, you’ll be well on your way to successfully cutting those bricks like a pro!

What Should I Do If The Blade Gets Stuck In The Brick While Cutting?

Here’s what you should do:
First off, turn off the grinder immediately and give it some time to cool down before attempting to remove the blade.

Then, try gently rocking the blade back and forth while applying pressure to see if it will move out of the brick.

If that doesn’t work, use pliers or vice grips to wiggle it free – but be careful not to damage the blade or hurt yourself in the process.

Remember, accidents can happen even with experienced DIYers so always take precautions when working with power tools!

Can I Use Water To Cool Down The Blade While Cutting Bricks?

The answer is yes – using water can definitely help keep your blade from overheating and getting damaged during the process.

Just make sure to use a steady stream of water, rather than just spraying it haphazardly all over the place (because that could potentially cause some safety issues).

Overall, adding some H2O to your brick-cutting routine is totally doable and can help ensure that everything goes smoothly.

How Do I Prevent The Dust From Cutting Bricks From Getting Everywhere?

1. Try to position your work area in a spot where the wind won’t blow the dust everywhere. You can also use a vacuum attachment on your grinder or lay down a tarp to catch the debris.
2. Use water to bind the dust particles. When you spray water, it not only cools the blade but also prevents dust from floating around in the air. It is important to spray around continuously and not just on the cutting blade.

With these simple steps, you’ll be able to cut those bricks without making a mess!

What Is The Best Size Angle Grinder To Cut Brick?

When it comes to cutting bricks with an angle grinder, I’ve found that the best sizes are typically 4.5 inches (115mm) or 5 inches (125mm) in diameter. These sizes give me enough cutting depth to get through a standard brick, while still being lightweight and easy to handle.

Larger ones, like the 7 inch (180mm) or 9 inch (230mm), can also be used for cutting bricks, but I find them to be heavier and harder to maneuver, and usually not necessary for most brick-cutting tasks. Ultimately, the size of the angle grinder I choose depends on the job I’m doing and my personal preference and comfort level.


Overall, cutting bricks with an angle grinder is a fairly straightforward process. As long as you take the necessary precautions and have the right equipment on hand, you should be able to get the job done quickly and efficiently.

That being said, it’s important to remember that safety should always come first when working with power tools. Make sure you wear protective gear like goggles and gloves, and never hesitate to ask for help if you’re unsure about anything.

With a little bit of practice and patience, you’ll soon become a pro at cutting bricks with your angle grinder!
