What Is an Angle Grinder?
An angle grinder is a versatile tool that can be used for numerous projects. Angle grinders are not only for grinding metal; you can use them for polishing and sanding, too. Angle grinders typically have a disc that is made of abrasive material, such as aluminum oxide or diamond.
Why Use an Angle Grinder to Cut Metal?
Angle grinders are useful for many different projects, but they’re especially adept at cutting metal. Metal is a difficult material to cut through, so it requires more energy.
An angle grinder is able to provide that power thanks to its electric motor. Additionally, angle grinders typically have a higher speed than other types of saws, which makes them ideal for cutting through metal.
How to Cut Metal with an Angle Grinder
Now that you know the advantages of using an angle grinder to cut metal, let’s go over the steps required. There are a few things to remember when using an angle grinder on metal.
First, make sure that you are using the correct disc. For most metal cutting applications, you will want to use a disc that is made of abrasive material like aluminum oxide or diamond.
Second, ensure that the disc is securely attached to the angle grinder.
Third, always use gloves and eye protection when operating an angle grinder.
When cutting metal, always start with the angle grinder turned off. Once the blade is touching the surface of the metal, you can then turn on the power.
With these tips in mind, let’s go over a few specific examples of how to cut metal with an angle grinder. [2]
Angle Grinder Safety
Using the Correct Blades Cutting techniques
Angle grinders are handheld power tools that can be used for a multitude of purposes. While they are mostly used for grinding down or cutting through metal, they can also be used for other materials such as wood or plastic. A common question people have angle grinders is if they can be used to cut metal. Cutting metal with an angle grinder is possible and even fairly simple to do. Although angle grinders are versatile, there are a few things you should remember before cutting metal.
First and foremost, you need to make sure that you are using the correct blades. Angle grinders come with a variety of different blades and each one is designed for a specific purpose.
Utilizing the Safety Guard
Be sure to attach the safety guard before beginning to cut. The safety guard is there for a reason and it is there to protect you from the blades.
If the blades were to come into contact with your skin, they could cause serious injury or even death.
Ensuring Workspace Safety
Another important safety tip is to make sure that your workspace is clear and free of any debris. The last thing you want is for something to get caught in the blades while you are cutting metal. This could cause serious damage to both your angle grinder and your workspace.
Use in a Ventilated Area
Because angle grinders create a lot of dust and debris, it is important to use them in a well-ventilated area. If possible, try to do your cutting outdoors so that the debris has a place to go. If you must do your cutting indoors, be sure to open up all of the windows and doors to ensure proper ventilation. [3]
Wear Appropriate Protective Gear
Finally, be sure to wear the appropriate protective gear when using an angle grinder. This includes eye protection, ear protection, and gloves. Angle grinders can be very loud and the blades can cause serious injury if they come into contact with your skin. Wearing the appropriate protective gear will help to keep you safe while you are using your angle grinder.
Wear Personal Protective Equipment
Eye Protection – Wear safety glasses or goggles, or a face shield (with safety glasses or goggles). Some models are equipped with an integrated dust collection system to reduce exposure.
Hearing Protection – Use earplugs or earmuffs. Angle grinders can be very loud.
Gloves – Wear gloves to protect your hands from flying debris and sparks.
Dust Mask – If the grinding tool is not equipped with a dust collection system, wear a dusk mask to avoid inhaling the dust.
Long Sleeves – Wear long sleeves to protect your arms from flying debris.
Closed-Toe Shoes – Wear closed-toe shoes to protect your feet from flying debris.
Choosing the Right Cut Off Disc
Disc Composition
Angle grinders come with different disc compositions, each designed for a specific type of cutting.
You can also ask an employee at your local hardware store for recommendations.
Durability
Another factor to consider when choosing a cut off disc is durability. If you’ll be using your angle grinder for heavy-duty cutting, you’ll need a disc that can stand up to the tough material. For example, if you’re cutting through concrete or stone, you’ll need a disc made from abrasive materials like silicon carbide or diamond. These discs are more expensive than those made from aluminum oxide, but they’re also much more durable and will last longer.
Cutting Speed
When selecting a cut off disc, it’s important to consider the speed at which it will cut through the material. Some discs are designed to cut quickly, while others are better suited for making precision cuts.
Disc Thickness
The thickness of the disc also plays a role in the speed of the cut. A thinner disc will require less pressure to cut through the material, which means it will cut faster. However, a thinner disc is also more likely to break under heavy-duty use. If you’ll be using your angle grinder for heavy-duty cutting, you’ll need a thicker disc that can withstand the added pressure.
How Deep You Need To Cut
Another factor to consider is how deep you need to cut. Some discs are designed to make shallow cuts, while others can cut up to 3/4 of an inch deep. If you’re not sure how deep you need to cut, it’s best to err on the side of caution and choose a disc that can make deeper cuts. That way, you’ll be able to make shallow cuts if necessary without having to replace the disc.
Disc Type
When you’re shopping for a cut off disc, you’ll also need to decide what type of disc you want. The most common type is the standard, which is designed for general-purpose cutting. There are also thin discs, which are good for making precise cuts, and turbo discs, which are designed for cutting through tough materials.
Size
Finally, you’ll need to select the right size disc for your needs. Angle grinders come with different size discs, so be sure to choose one that will fit your machine. You can usually find this information in the angle grinder’s user manual.
