Things to Consider Before Buying a Variable Speed Angle Grinder

Types Of Models (Power Source)

The first and foremost thing to think about is the type of variable speed angle grinder you want to have in your tool collection.

This factor will directly contribute to your quality of work. There are three different types for you to choose from based on the power source.

Cordless models are designed to satisfy your need as a handy tool that works well with any material.

Since this type is battery-powered, you should pay attention to the battery level to ensure it will not affect your work in between.

Thanks to the cutting-edge technology, you can expect faster recharge and longer use from the cordless product.

Corded angle grinders will provide you with powerful and long-lasting performance. This kind of model doesn’t require recharging, making it more convenient to use at any time.

The excellent power capacity of this model will help you deal with diverse projects, especially difficult and heavy ones.

Pneumatic angle grinders can be seen as the updated version of corded models. This type of grinder can operate well without an electric motor or battery, giving you a comfortable experience.

It is a lightweight and wallet-friendly model that is worth considering.

Variable Speed

Speed plays an important part in the powerful performance of an angle grinder. The average speed range of a variable speed model is from 5,000 to 10,000 revolutions per minute.

Grinder speed

According to your preference, you can choose between a small and large angle grinder. Bear in mind that larger angle grinders will have lower speeds than smaller ones, reducing your work quality.

Having a powerful tool with fast and variable speed will ensure your satisfactory result. With the speed setting option, you can optimize the product by selecting various speed ranges suitable to your needs.

Disc Size

Another key feature that you should take into consideration is the disc size. The disc of the angle grinder will measure the power and total capacity.

Generally, the disc range varies between 4 and 9 inches, allowing you to choose the most suitable size.

It is highly recommended to choose the disc size according to your type of work and the material you use. Each one requires a different size to ensure the optimal result.

Angle grinder discs

If you prefer the disc performing well with a fast pace of work to produce the best finish, go for a large-sized disc. The small one will do you good when it comes to meticulous jobs with tight angles or small spaces.

Safety Features

In addition to the above suggestions, safety features are also of great importance to your final buying decision. This factor will help protect you from the risk of injury while working.

You had better check some items like disc guard, disc brake, locking system, etc., to ensure that your angle grinder will work well under safe control.

Take all aspects into consideration, and it would be helpful to ask for advice from professionals before jumping to buying conclusions.
