 How to pick the best angle grinding wheel for cutting metal?

Actually, it is quite obvious that you think that it is simple to choose the most suitable angle grinding wheels, given the great offer on the market. However, when you are really about to buy, you realize that choosing the best wheel is the toughest thing to do. Well, yes, the task is tricky. But we have taken the delight to guide you with some key considerations when buying the best grinding wheels.

Choosing the cut-off wheel profile

Before buying the best disc for your angle grinder, you have to understand the types of discs that exist. There are primarily two kinds of cut-off wheels you will see. One is the flat type and the second is the recessed center type.

But most of the angle grinders we use are compliant with the flat discs. Once more, the flat disc type is actually more efficient at cutting metals, plastics, and more. They are more multi-purpose.

Whereas, centered grinding wheels are better for overhangs or tight corners. Thus, it is preferable to go for flat discs to get a superior cutting performance.

Construction material and grain

The majority of the best angle grinding wheels for metal cutting are constructed of aluminum oxide grit. Indeed, these are the preferred materials for discs. The material offers a smoother bond to the creation, thus making the discs easily controllable and providing fast-cutting characteristics.

Also, the material confirms that there is no iron in the discs. This is important if you want to cut both mild and stainless steel with your discs. However, it is better if the label on the wheel says that it is INOX quality.

Quality of the abrasives

This is another point to consider. In order to get the highest strength and toughness from your grinding wheels, you should make sure that the wheels contain high-quality abrasives. The chemical compounds used to produce the abrasives should be of high quality.

Otherwise, the discs will not provide a smooth cut. They will also not be hard enough. Only the best chemically formulated abrasives can provide a hard, sturdy, and tough wheel.

The thickness of the cut-off wheels

There are many cut-off wheels with different thicknesses. But only a cut-off wheel with standard thickness can provide precise and smooth cutting of metal or plastic. However, for everyday tasks, most discs are offered with a thickness of 1.6 mm.

For cutting sheet metal, a 0.8 mm thick disc is more suitable because it is a thin metal. For heavy tasks such as cutting heavy metal, a disc with a thickness of 1.6 or 2.5 mm is needed. Therefore, choose the right disc based on the job application.

Number of discs

You will have to choose on this point in accordance with the nature of your work. If you are an average do-it-yourselfer, you can opt for a single piece of disc. But a professional handyman will need several discs for different applications. So set the goal.

Ease of use and durability

If the grinding wheel has a balanced size and diameter, it is also easy to install. If you are not going to do heavy cutting or industrial work, it is advisable to use a disc with a smaller unit.

Again, if the discs are produced from high-quality material, they will last longer than you can imagine.


We are done with the reviews of the best angle grinding wheel for cutting metals. We have tried to give you all the information about grinding wheels so that you could pick the one you need to perform most of your cutting tasks efficiently.

And remember, when you want to prevent yourself from injuries, please don’t forget to wear safety clothes before starting the job.
