  • Hearing protection
  • Dust mask/respirator
  • Metal cutting wheel

6 Steps Guide on How to Cut Bricks With Angle Grinder

Step 1: Put on Safety Materials

When using an angle grinder to cut bricks, it is important to remember that the machine emits sparks. Due to the potential danger of these sparks, you must always wear safety glasses, hearing protection, and a dust mask/respirator. 

With this equipment on, you can be reassured that you’re taking appropriate precautions while completing your brick-cutting project. In addition, think twice before starting the project as angle grinders are powerful tools best used with caution when cutting or grinding bricks.

Step 2: Mark the Line

Use a Pencil to Mark the Area

When it comes to cutting bricks with an angle grinder, accuracy is key. Before you begin, use a pencil to mark the area where you need to make your cut. Make sure to double-check your measurements and draw a neat line on the surface of the brick that will help guide you through your cut. 

Paying attention to precise details at this stage will set up a successful cut, so be sure not to rush it. With a pencil marking as your guide, you’ll be able to achieve an accurate and precise cut with your angle grinder much more easily.

Step 3: Keep the Angle Grinder at a 90-degree Angle

When it comes to cutting bricks with an angle grinder, safety is paramount. To ensure you keep your fingers away from the spinning wheel and gain optimal accuracy, hold the angle grinder with both hands and aim to keep the machine at 90 degrees vertically to carve evenly into the brick. 

Before you begin spending energy and time on this effort, make sure the cutting surface is clear of debris and carefully locate the intended cut line on your brick wall for a precise finish. Hold your breath as you switch on the angle grinder, guiding its movement along the chosen line until your desired measurement is complete.

Step 4: Apply Light Pressure

When it comes to cutting bricks with an angle grinder, accuracy and precision are key. Avoid pressing down too hard on the grinder wheel as this can cause an uneven cut or even cause the wheel to shatter due to too much pressure. 

Instead, applying light pressure and moving the wheel slowly along your marked line helps ensure control and accurately cuts through bricks. The slower you move, the more precise and comfortable the cut will feel – plus it gives you more time to react in any unexpected situations that may pop up during the process.

Step 5: Stop Cutting

Cutting bricks with an angle grinder is a relatively straightforward process, yet it is important to take all necessary safety precautions to ensure that the job is properly completed. 

Before beginning, you should mark the brick as per your required cut and make sure to double-check measurements so that you do not end up making sloppy cuts. When using an angle grinder, it’s important to remember to stop cutting when you’ve reached your marked line. 

Stop Cutting When You've Reached Your Marked Line

Taking this extra step will allow for smoother edges, which will help in the overall look of your finished project. Additionally, stopping at the marked line can help minimize unintentional mistakes and minimize the risk of injury.

 With these few tips in mind, you should be prepared and well-equipped to make precision cuts when using an angle grinder!

Step 6: Turn Off the Angle Grinder

To cut bricks with an angle grinder, first ensure that you have the right type of blade or disc for the job. Before beginning, turn off the angle grinder, and be sure to wear protective gloves and eye protection. When cutting, take care to stay outside of the dust cloud created by the spinning disc to prevent any debris from getting into your eyes or on your skin. 

Once finished, turn off the angle grinder and use a brush or vacuum cleaner to remove any dust and debris from the cut area. This will help improve visibility when inspecting your final cutting result and reduce the risk of breathing in any harmful dust particles. 

Additionally, it’s often helpful to clean away any mortar surrounding the area you are cutting as it can become a hazard if left loose on the surface while working with an angle grinder.

And there you have it! Now you know how to cut bricks with an angle grinder. Always remember to stay safe when using an angle grinder, and happy cutting!

Tips to Cut Bricks With an Angle Grinder

  • Always use a sharp blade.
  • Make sure the angle grinder is set to the correct speed.
  • Cut along the score line with light pressure.
  • Apply more pressure as you reach the end of the cut.
  • Use a wet saw if possible.
  • Wear eye protection and gloves.
  • Practice on scrap bricks before cutting the bricks you need.
  • Mark the bricks with a pencil before cutting.
Wear Eye Protection and Gloves

How to Ensure a Precise Cut When Cutting Brick with an Angle Grinder?

If you’re using an angle grinder to cut brick, it’s important to ensure your cut is precise. To do this, start by connecting a diamond cutting wheel to the grinder for maximum accuracy. 

Be sure to allow the wheel time to reach full speed before you start cutting through the brick, as this will help reduce any chipping. When making your cut, be sure to stabilize the brick with a clamp and hold the grinder firmly in place rather than moving it back and forth. 

The process will go much faster if you use several steady cuts over a single protracted movement. Afterward, make sure that you have shut down, unplugged, and cooled down the machine before performing any maintenance on it. Following these easy steps can help ensure that you end up with clean and accurate cuts when using an angle grinder on brick.

How Can I Make Sure My Cut is Precise When Using an Angle Grinder?

When using an angle grinder for precise cuts, selecting the correct accessory for the job is key. For instance, a diamond cutting blade is suitable for tiles but unsuitable for metals. Picking the right disc also goes a long way in producing neat and precise cuts; thin discs work best with fiberglass while thicker discs are great for masonry and steel. 

Additionally, maintaining high RPMs is imperative when making clean cuts – start slowly to avoid overloading your grinder and gradually speed up as you go along. 

Lastly, make sure to affix your grinder correctly on the material by using a clamp or other type of support to keep it steady so that you can accurately direct it and control its motion. Following these simple tips will result in professional-looking precision cuts every time!

What Type of Blade Should I Use to Cut Bricks With an Angle Grinder?

If you’re looking to cut bricks with an angle grinder, the type of blade you should use depends on the materials that the brick is made out of. For harder materials like clay bricks, a diamond masonry blade is recommended since it can not only slice through the material but also chip it away cleanly. 

For softer materials like concrete blocks, a segmented rim blade can be used which has diamond particles embedded into the rim that allows for more efficient cutting of the surface. Remember to wear safety equipment such as a full-face shield and protective gloves when operating an angle grinder, especially when working with masonry blades!

Remember to Wear Safety Equipment

How Do You Prevent Chipping When Cutting Brick With an Angle Grinder?

When cutting brick with an angle grinder, it is important to take certain precautions to avoid chipping. An angle grinder that is too powerful for the brick can create more vibration and result in chipping.

For this reason, make sure the motor of your angle grinder matches the strength of your brick and use the appropriate cutting disc. Additionally, use a grinding wheel guard to keep the spinning disc away from any bystanders, and wear safety glasses while working. 

When making cuts into brick, work slowly and steadily to help keep even pressure on the blade’s surface and reduce vibrations. Lastly, be aware that some brick will naturally chip no matter how careful you are; because it is porous, extra care is needed when using an angle grinder if you want to minimize chipping as much as possible.


Bricks are a versatile and strong building material. They can be used for walls, floors, foundations, and much more. You should carefully determine how to cut bricks with angle grinder. 

When you need to cut bricks, it’s important to choose the right tool for the job. An angle grinder is a powerful handheld tool that can easily cut through brick. With the proper safety precautions in place, you can use an angle grinder to quickly and safely Cut bricks for your next project.
