Do I need a Variable Speed Angle Grinder?

Angle grinders with variable speed allow you to control the grinding wheel speed. They definitely come with a number of advantages over the single speed grinders. For instance, they’re quite versatile and suitable for multiple applications.

While most people can make do without a variable speed angle grinder, some projects actually need them. So, whether you need a variable speed angle grinder or not comes down to your needs, really.

Sometimes, the single speed of 10,000 RPM might be too much for the material you’re handling. With a variable speed angle grinder, you can easily reduce the speed so that you can be more precise and add more intricate details. This way, you won’t have to buy another grinder just because you need reduced speed.  

Both of the angle grinder types can work with equal efficiency, but the ones with variable speed can prove to be more useful for delicate projects. So, if you value the advantages they provide, you should definitely go for them. Our variable speed angle grinder review should help you to be hooked up with one ASAP!

Things to Check Before Getting One

It’s always a wise decision to take certain things into consideration before buying something. That’s more apparent when purchasing a variable speed angle grinder because if you fail to choose the right one, you won’t get to do much grinding.

So, if you don’t want to end up with a useless product, make sure to check the following things before purchasing from our variable speed angle grinder reviews.

Grinder Size

The size of your grinder matters a lot in finishing your works perfectly. As they come in various sizes, you have to understand how they fit in. For instance, larger grinders are great for handling larger jobs. However, they can’t spin as fast as the smaller ones.

On the other hand, the smaller grinders are more useful for delicate projects where you need to be extra-accurate. They are also way faster than the others.

Speed Rating

Speed rating tells you about how fast the wheels of the grinder can spin. Faster spinning means more effective and faster-grinding operation. So, go for the fastest one that you can afford. Most of the grinders are available at 5,000 to 10,000 RPM speed. Some are even capable of reaching 12,000 RPM. However, if you are going for the maximum speed, you should know the grinding wheel safety measures properly.

Durability

Your angle grinder should be built with high-quality materials. In addition to that, the motor must be protected from the outside elements. There should be a feature that keeps the dust away. Overheating can damage the grinder, so you should opt for one that offers overheating protection.

Weight

Angle grinders are available in different weights. You should go for a weight that feels comfortable to you. If the grinder feels heavy, you would have to work with limited control, and you’ll tire yourself out too quickly.

There are many lightweight options that offer fantastic performance. We’ve made sure to include them in our variable speed angle grinder reviews.

Ease of Use

Angle grinders must be easy to operate, control, and maintain. Some features can make them easier to use. If they have adjustable handles with an ergonomic design, you’ll have better control over the grinding. You should be able to change the wheels whenever you want without any issues easily. We have made a DIY welding table. You can read our experience to know why the ease of use is so important.
