In the sea of many hand-held tools, it is the angle grinder that seems to be the most versatile. It comes as no surprise as this particular product is successfully used in many spheres, including the automotive industry, plumbing, carpentry, and many others.

It is quite clear that by investing in an angle grinder, you will be getting a tool that can be handy with most of your DIY work as well. Its main feature? A cutting wheel (not a blade) that is responsible for sliding through hard materials such as bricks, concrete, and tiles.

There is one question that is quite common on the relevant boards, and that is: “Can an angle grinder cut metal?” The simple answer? Absolutely! In fact, this tool was primarily designed for refurbishing and polishing materials such as metal, so it shouldn’t surprise you that as long as you have enough patience cutting through it, it should be quite easy.

Still, you shouldn’t go into the process without any precautions. We prepared a few safety tips on how to cut metal with an angle grinder the most efficient way.

The Mechanism of an Angle Grinder

As we mentioned above, the angle grinder is one of the most popular products on the relevant market. There are a number of different variations of angle grinders; they come in different sizes, and with or without a cord.

The most common one seems to be the 4-inch model, and running on a motor that has a power of anywhere from 5 to 9 amps, which is enough to deal with most hard materials. 

Apart from that and the cutting wheel, a good angle grinder comprises  a spinner washer, comfortable handle, and a protective cover. But how can an angle grinder cut metal? Mostly because it can achieve up to 15,000 rotations per minute.

How to Cut Metal With an Angle Grinder

Now that you understand the concept of an angle grinder, it is time to move on and see what the best way to do it is. We have to suggest that the process is not always the same, as various angle grinder models function differently. Still, the precautions that you need to take are pretty similar.

First and foremost, you should ensure that you have all the required tools for this process. Apart from the angle grinder, this includes a power source and a long cable (unless it is the cordless model), along with the earmuffs, goggles, C-clamp and an adequate metal disc. Last but not least, you should have the metal that you want to cut, set and ready.

Once you have all the tools set and ready in place, it is time to prepare the angle grinder for the cutting process. That is done by attaching the appropriate metal disc and putting the spindle nut in the right place.

Also, unless the angle grinder that you are using is cordless, this is the time to plug it into a power source. The next step is to fix the metal and mark the cut with a permanent marker. Once you have done that it is time to begin the process. Hold the angle grinder with both of your hands and start cutting with firm precision. Follow the line that you have previously marked and control the kickback ensuring that the cutting is light and smooth.

If there is a need for changing direction you should do it pretty carefully without any intense or sudden moves. This way you will protect yourself from injury and ensure that the cut remains precise. Once you are done, check for any rough edges and use a flipper to correct these. 

What we personally recommend is to finish the cutting work once you have already started it. Doing it halfway and leaving it for another day, can only increase the chance of an imprecise cut, or injury, if you are not patient enough the second time around.


So can an angle grinder cut metal? Yes, it can. At the end of the day, using the angle grinder to cut metal can be absolutely safe as long as you have the right equipment and safety tools with you. 

It is made to cut through harder metals, as well as bricks and concrete, so you shouldn't worry about the tool breaking down. Make sure that you are safe with full control over it and you will be good to go. So all that is left now is to choose your material and get cutting.
