Electric angle grinders are the most common type. They are powered by either plugging them into wall sockets, using batteries or through a transformer for professional and building projects. This type of grinders is great for light to medium tasks, which means that it can be ideal for DIY applications.

If you want to buy the best angle grinder, you first have to know what makes the best angle grinder. Without much talk, let’s see what to consider in order to get the best angle grinder available on the market.

Disc Size

Size of Angle Grinder

If you are shopping for an angle grinder to polish or grind surfaces that are difficult to reach, then a small-sized angle will be your best pick. Small sized angle grinders are usually light and easy to handle. Moreover, small angle grinders are the best when it comes to sharpening blades as well as clearing rust and paints from metal surfaces.

Large-sized angle grinders, on the other hand, are ideal if you are planning to work mostly on metal. This is because you will need an angle grinder of more than 9 inches to cut through heavy steel pipes.

Power Sources

Just like power tools, angle grinders also need something to power them. In most cases, the common source of power used by angle grinders is the electric motor. Power is drawn from the mains of around 230V or 110V in case you use a transformer. Apart from the mains, some angle grinders run on 18V Li-ion rechargeable batteries.

Another type of power source is compressed air. Angle grinders that are powered using compressed air are usually meant for professionals and are usually bigger and powerful as compared to electricity-powered grinders. Before you settle on an angle grinder, therefore, you need to think about the kind of power source that you will be comfortable using or that is readily available.

However, be ready to pay more for that.

Disc Types

Usually, you can use small and large angle grinders for the same kind of components. You only need to use the right kind of discs, which means that you must identify the disc that goes into the best angle grinder. The type of disc you will use will depend on the kind of projects you will be carrying out.
