Looking at the power tool market, there is a good chance that you will find a lot of angle grinders at various asking prices, and there is a good reason why. This versatile tool is used by many handymen, including plumbers and mechanics, and even people that enjoy do-it-yourself work who have at least one of these in their home. 

But what makes this product so good? Apart from being great for cutting through hard materials such as concrete, brick or metal, it is good for polishing and refurbishing things around the house.

Among the high demand, one particular variation became quite popular and that is the cordless angle grinder. It doesn’t need to be plugged in and it runs on batteries, but does that mean that it is better than the traditional version? It all depends on the model and the brand that you are buying.

While it is certainly more portable and convenient, some don’t have enough power to cut through different hard materials. We need to go further into detail in order to answer the question: “Are cordless angle grinders any good”? Let us take a look at the answer as well as a few benefits.

The Benefits of Cordless Angle Grinders

Before we can answer the question, we need to take a look at the potential benefits that come with it.

First and foremost, using a cordless angle grinder is great if you are dealing with metal and you need a power tool that is strong enough to perform polishing. There is no better product to remove rust and old paint than an angle grinder. Along with that, if you have the right safety equipment, cutting through metal will be quite easy as well.

A cordless angle grinder can be used for things like carpentry and cutting edges, which make it applicable in different industries and do-it-yourself work.

The main benefit of using a cordless angle grinder certainly is that it is more portable and easier to maneuver, due to the lack of a power cord that is common for a traditional one. Also, in most cases, it won’t weigh as much as some of the other power tools, making it a good choice for someone who is getting familiar with the concept of cutting bricks, concrete, and metal.

The Main Features of a Cordless Angle Grinder

To find out whether cordless angle grinders are any good, we need to discuss the main features of this product. As we mentioned above, it is the battery that keeps this product running, and if it is not of high quality, then the motor and other components will not be worth anything. However, buying one that has lithium-ion batteries is a long-term investment that will allow you countless heavy uses, before they need replacement.

Along with that, the other major component is the motor that it uses to cut through that material. While brushed motors are cheaper and more effective, especially if you are going to put the grinder through heavy use, buying a brushless angle grinder is going to be better in the long run.

Yes, the price is higher, but you are also getting a product that weighs much less and is more easy to maneuver. Along with that, most models that don’t include brushed motors are more powerful as well. 

Should You Buy a Cordless Angle Grinder?

This still doesn’t leave us with a clear answer of whether you should get a cordless angle grinder, or stick to the traditional variation. In our opinion, it all comes down to your needs and budget.

If you have a more flexible budget and you enjoy working with this power tool, a cordless angle grinder is certainly a great decision. The reason? It is lighter, more powerful and easier to use than a traditional one. On top of all that, the fact that lithium-ion batteries will last long mean that in the long run, you will be saving funds for another handy tool!


As we mentioned earlier, a cordless angle grinder is a product that is just winning the market, and there is yet to be a final verdict on it. We think that it is worth its price, as long as it has a good quality battery and doesn’t include a brushed motor. If you are an enthusiast that loves working with power tools, we say you give it a go! Cordless angle grinders are definitely good to have in your power tool arsenal.
