The problem is; the market is full of different kinds of angle grinders, and each manufacturer claims to offer the top product in this category, which makes picking the best angle grinder for your garage seem like an impossible task.

So, let’s cut to the chase, shall we?

Types of Angle Grinders

Angle grinders come in three varieties: corded, cordless, and pneumatic.

Corded Angle Grinders

Corded models are typically the most powerful, but they’re also heavier in weight and bulkier in size. The inconvenience to such machines is that you need constant access to a power outlet. On the bright side, a corded angle grinder will provide enough power for any project of any size, making this type the most suitable for heavy-duty jobs.

Cordless Angle Grinders

Cordless models are smaller and lighter compared to corded ones, but they’re also a tad bit less powerful. However, the weight of the battery pack may sometimes offset this advantage.

The main selling point of cordless angle grinders is their portability, as you can easily move one around and use it at remote locations effortlessly. Besides, battery technology is really taking off, and the charging times for battery-powered angle grinders are getting shorter and shorter every day. Maybe we won’t even need corded models in the future.

Pneumatic or Air Angle Grinders

Finally, pneumatic angle grinders. These tools are cheap, lightweight, and don’t require an electrical power outlet or batteries to function. Just plug one of them into your air compressor, and it will be up and running in no time.

This is the best type for tradesmen who already work with many pneumatic tools, as it will help them put their compressor to good use.

DEWALT DCG413B – Best Cordless Angle Grinder

Right off the bat is a cordless angle grinder from one of the world’s most known brands – DEWALT.

Best Cordless Angle Grinder Thanks to its 20V (max) motor, this unit can deliver a maximum no-load speed of 9,000 RPM.

Picking the Top Angle Grinder – Buying Guide

Choosing the right tools for your garage, workshop, or job-site is no walk in the park. Machines like the angle grinder can make all the difference between a perfectly-done project and a lousy one. That’s why you need to go over a set of vital factors before making up your mind as to which unit shall be your best angle grinder.

Power and Speed

As you know, power is the main perk of a power tool. Here, there are two kinds to consider: the input power, and the output power. The first is measured in three measurement units depending on the type of the angle grinder:

  • Amps (A) for corded grinders.
  • Volts (V) for cordless grinders.
  • Cubic feet per minute (CFM) for pneumatic grinders.

The output power, on the other hand, is measured in watts (W).

Obviously, how much power your ideal angle grinder will have will depend on the kind of projects you tackle more often. If you’re looking to take care of heavy-duty tasks, say metal cutting, for example, you ought to get a unit that offers plenty of power, but you’ll probably have to pay up extra upfront.

As for the speed, the rule is simple; the bigger the attached wheel, the slower the machine. To compare different angle grinder models, you’ll have to check their no-load speed, which is measured in RPM, or rotation per minute. The no-load speed refers to how fast the motor can rotate when no disc is installed.

Angle grinders can deliver different speeds, which range from 5,000 to 11,000 RPM. These machines are pretty fast, which means that they’re really dangerous as well, so make sure to wear your safety equipment when using one.

Supported Wheel Size

Angle grinders serve different purposes, and using them for various applications is as simple as switching the wheel or attachment. Now, while the material of the disc will determine what kind of surface you can use it on, its size will determine how deep you can cut.

While opting for an angle grinder that supports big discs, say those measuring 7 to 9 inches, for example, may seem tempting, it can actually be overkill if you’re not planning to use the tool for heavy-duty applications. That’s why we usually recommend going with a 4 1/2 angle grinder that supports 4 to 4.5-inch discs. That’s the optimal wheel size for most uses, and it’s the one you’ll easily find at any hardware store.

Angle Grinder Safety

No matter which tool you’re looking for, be it the electric angle grinder, circular saw, or impact wrench, you must pay great attention to the safety as such machines can be dangerous. Some of the safety features that we recommend looking for in a quality angle grinder includes the anti-kickback clutch, which protects you from kickback, and the two-stage trigger or lock-off switch, which lowers the risk of accidental starts of the machine.

Safety Guard

All the models we reviewed got safety guards supplied with the tool. You might have noticed that when grinding metal you get a lot of sparks. These are small metal and abrasive particles and high temperatures. Without a proper cover, these long sparks can cause fire hazards especially if you are working in a garage or closed area.

Similarly, while you cut tiles, stones and other masonry the flying debris can cause injuries. Hence a protection guard for angle grinder is a must in many cases.

Dust Protection

Angle grinders produce a helluva lot of dust, which can wreak havoc on the interior of the machine. When picking the best angle grinder, look for one that has an efficient dustproof system to keep the internal parts from harm’s way.

Other Features

Some angle grinders come with extra features that can really make your work easier, such as the lock-on switch, which allows you to keep the tool running without having to keep pressing the switch.

A soft start handles is also a great feature to have in a good angle grinder, as it reduces vibration, which can make your work easier, especially during extended operations.

Tool Warranty

If there’s one thing that reflects how much trust a manufacturer has in its products, it has to be the warranty. That is why you need to check the coverage of every unit before picking the right angle grinder. The standard is three years these days, but many models still come with a shorter warranty.


Getting the best angle grinder on the market is no small feat, but it’s doable. Each of the above products is suitable for a specific application/use case, which is why you need to read our buying guide carefully and take your time before making up your mind.
