Types of Angle Grinders

You’re now armed with the names of the best angle grinders. But it’s not enough to know a few names. You must also learn more about angle grinders in general. Did you know that there are three types of them based on power source? Here’s a little more about them:

Corded Angle Grinder

These are designed with a cord that connects you to the power output point at the project site. You have to plug it into the power source and can then continue to work for an indefinite time. There’s no reason to worry about running out of battery while working!

These are lighter and smaller than battery-powered grinders. These features enable a continuous running time. But the cord allows you to work within a limited space only. You must stay within the power outlet range. Plus, the cable may tangle or make your trip.

Cordless Angle Grinder

Cordless angle grinders are powered by a battery. Hence, you don’t have to worry about looking for a power source to start working. You can carry it around anywhere for indoor and outdoor projects. They are excellent when you work on a ladder or a scaffolding.

Cordless angle grinders cannot work infinitely, as the battery needs to be changed from time to time. This means you’ll lose 30-60 minutes in the middle of your work. Plus, they can be slightly heavy. The better speed and power they provide, the more expensive they’ll be.

Pneumatic Angle Grinder

A Pneumatic Angle Grinder is considered an upgraded version of an electric angle grinder. This grinder is powered by air pressure instead of batteries or electricity, which is why it is also called an air grinder. You have to plug it into an air compressor unit for power.

However, pneumatic angle grinders are costlier than electric corded grinders. Another major issue with this type of grinder is that there might be a lack of proper air pressure setup to power it. That’s why many people avoid it despite its overall incredible power and performance.

Best Angle Grinder Buying Guide

You now know that there are three main categories of angle grinders based on the power source. You’ll find different types of tools on the market. They vary in motor power, design, and more. It’s time to know about other factors to consider while buying angle grinders:

Disc Size

Angle grinders come in a wide variety of sizes. And the size is largely dependent on the diameter of the wheel or disc that can be fitted into the device. The disc size can be as small as 4 inches or as large as 9 inches. Depending on the usage, choose the disc size.

If you want to use the angle grinder for hobby projects, a disc of 4”, 4.5”, or 5” should be sufficient for you. Grinders that use these discs are small and light – ideal for DIYers and new users. However, if you are ready to handle more weight, you can afford larger discs.

For professional or industrial use, discs as large as 9″ might come in handy. This is especially true if you want to use the device for thick and dense materials. These discs can only fit into large angle grinders, which are a little more exhausting to use for a long time.

Power Source

Angle grinders may draw power from batteries, electricity, or compressed air. Accordingly, the device design and area of usage will also differ. Electric angle grinders are the cheapest of the lot. They are corded devices that need to be plugged into a power source.

While corded tools can be operated endlessly, you can only use them within a specific area close to the power source. That’s where a battery-powered cordless angle grinder may seem more convenient. It can be used anywhere – both indoors and outdoors.

However, you may have to stop frequently to charge a cordless grinder. It can also be a little heavy. A pneumatic grinder, using air pressure for power, is a great overall choice. But finding an ai-line setup to power the device is not always easy to find, thus causing inconvenience.

Speed

The speed of the angle grinder is indicated in terms of revolutions per minute, or RPM. The more revolutions its blade will make in a minute, the more robust and fine will be its cutting ability. The speed of an angle grinder usually starts as low as 5,000 RPM.

High speeds may be anywhere between 10,000 RPM and 12,000 RPM. You should remember that the RPM rating is determined when the device is in a no-load condition. This means that the disc does not actually have to cut or grind any material at the time.

The RPM rating is performed when the disc just spins in the air. So the speed lowers considerably when the device actually performs the job. It is still a trusted sign of the device’s speed. The higher the speed, the more force it can implement on hard materials.

Voltage and Ampere

An angle grinder’s power output potential is measured in terms of amperes (Amps) and volts (V). If it is a cordless angle grinder, you can expect them to be powered by 18V or 20V batteries. The outliers may range from 7.5V to 24V. The most common is 18-20V.

This is usually the most common type of cordless angle grinder. That’s because these tools are affordable and effective in different jobs. As for corded grinders, voltage reading simply indicates the power outlet that they are compatible with- 120V or 220V.

You can also check the amperage to know about a corded model’s power output potential. It usually ranges from 5 amps to 15 amps. If you want to buy a large grinder that can use a 7” or 9” disc, you can expect a higher power output potential as it is a heavy-duty machine.

Soft Start

Even the slowest and most basic angle grinders can be extremely fast and powerful. They can recoil when you turn on the power. The recoil can be exceptionally high-impact if the device is heavy and oversized. Recoil can be a dangerous thing and can cause severe injuries.

If you’re not careful enough or have a firm hold on the tool, it can jump out of your hands as a result of the impact. So, to combat this potentially threatening situation, many angle grinders are engineered with soft-start technology as a safety feature.

This technology ensures that the initial power supply to the device is at a reduced rate so that the tool gets a soft start. The power supply then increases slowly so that the grinder can reach its highest speed. The throttled control can reduce the force on your hands.

Hand Guard

When the angle grinder is at work, you may experience sparks due to friction. You may also see debris and dust flying around – and most of these move towards the user. A hand guard is thus a crucial feature of an angle grinder – one that is often ignored and overlooked.

The guard of the grinder can deflect debris and keep away sparks to protect your hands. It is a particularly handy feature if you are planning to use the device in tight spaces where these flying pieces of scraps or hot specks do not get the chance to dissipate.

Some grinders come with movable guards, while others have fixed guards. Movable guards are easier to adjust and hence, more popular. However, you must make sure that it is tight and secure, or it might fall off. Fixed guards are usually sturdier and won’t come off.

Handling

The final factor to consider while picking from a list of the best angle grinders is the handle of the device. Many grinders come with adjustable side handles that can be moved to two or three positions. Other grinders come with handles locked in a single position.

The advantage of adjustable handles is that you can pick a spot that’s convenient for you, depending on whether you are right-handed or left-handed. A movable handle thus gives you better control of the device and allows you to enjoy more comfort while working.

Besides being adjustable, there are other features of a grinder handle that can make your grinding job more convenient. Look for an ergonomic design that allows easy hand placement and doesn’t stress your wrists or fingers. A soft and anti-slip grip can be an added advantage.

An angle grinder can be used for a wide range of tasks, from grinding to polishing, from cutting to buffing. Browsing through the list of the best angle grinders can be confusing. That’s because they vary in application, design, motor power, and more.

The prices also differ based on the power source, design, and capabilities of the grinder. So while it’s easy to get tempted by a high-end angle grinder, don’t forget to consider how you intend to use it. We hope that our angle grinder reviews will help you pick the right one!
