How to Cut Aluminium with an Angle Grinder?

Cutting aluminium is a common need for many DIY projects. While there are various tools you can use, such as saws and circular saws, an angle grinder is the best tool for quick and precise cuts. Keep reading to learn more about how to effectively cut aluminium with an angle grinder.



Step 1 – Prepare Your Work Area

Before beginning your project, make sure your work area is set up properly. Be sure to wear safety glasses and protective gloves when cutting aluminium. You should also wear ear plugs or muffs to protect your hearing from the loud noise created by the angle grinder. You will also want to make sure that you are using a flat surface for cutting that has been cleared of debris. Additionally, you may want to consider marking out where you will be cutting with a marker or tape measure if possible.

Step 2 – Select the Right Blade

The type of blade you choose for your angle grinder will depend on the thickness of the material you are cutting. For thinner materials (1/4″ or less), a diamond blade is recommended because it produces cleaner, more accurate cuts than other types of blades. For thicker materials (over 1/4″), you should use an abrasive-cutting wheel since it can handle thicker pieces of metal with ease. Be sure to select a blade that is compatible with the size and speed rating of your angle grinder; otherwise, it could cause damage to your equipment or injury to yourself.

Step 3 – Start Cutting!

Now that you have prepared your work area and chosen the right blade, it’s time to start cutting! Make sure you hold the angle grinder firmly in both hands while keeping your arms straight at all times during operation. When making contact with the aluminium, push down gently but firmly in order for the blade to penetrate into the material without bouncing off or splintering away from it. Also, be sure not to move too quickly; take your time and slowly guide the blade through until it exits through he another side of the material. Once finished, unplug or turn off the power switch before cleaning up any debris left behind by your cut-off piece of aluminium.




Cutting aluminium requires precision and patience—but luckily, an angle grinder makes this task much easier and faster than other methods like sawing or drilling holes in metal pieces! With proper preparation, selecting the right blade for each job, and taking care when making contact with metal surfaces during operation, anyone can tackle this home improvement task! So if you’re looking for a quick way to cut aluminium for whatever project you have in mind—try using an angle grinder today!
