This grinder is an all-rounder and perfect for someone looking for versatility. You can actually use it with 4½ inch wheels, and even alternate with both 5 and 4 inch wheels.

We actually tested it with diamond cutting wheels, and it worked perfectly. 

Although most angle grinders are more or less somewhat similar in terms of features, the DCG413B is very unique. Its 9000 RPM is a rare feat to achieve, which makes it one of the most powerful grinders out there.

The best thing about the motor is that it can work long hours without requiring any maintenance. This is augmented by the fact that the grinder is brushless (doesn’t need change of brushes, thus increasing efficiency).

One other unique feature of the DeWalt 20V 9000 RPM grinder is the steel guard, which is of type 27 and is adjustable to operate in any direction. This makes your work easier.

For easier maintenance, the grinder has been designed for easy accessibility to its gearbox, whereby you just have to remove its shroud, and that’s it!

Better yet, it has a mesh-like vent that helps cool down the motor. This also minimizes dust particles from damaging the grinder’s machinery parts. Its trigger also comes covered by a boot, which further prevents debris from entering into it.

Some other safety measures include a kickback brake system, which stops the machine when it operates at a max force and a pinch or clutch has been sensed. This is a great addition to the grinder, and one of the reasons we chose it as our recommendable option.   

Basically, the DeWalt DCG413B comes with lots of safety measures without sacrificing its performance. For instance, the angle grinder has a two-stage trigger system. This allows you to activate a small trigger before pressing the paddle. Again, this avoids further accidental triggering of the grinder.

Pros

  • Easy to handle with butylene-rubber overmold, which makes it grippy
  • A mesh-like vent cools the motor
  • Designed to prevent debris from entering its machinery parts
  • A great battery life of about 12 minutes of non-stop cutting, which is pretty amazing
  • The tool is quiet yet very efficient with its versatile cutting needs

Cons

  • It comes as a “bare” grinder, meaning that you’ll have to buy DeWalt batteries separately

When testing it with various materials, we were impressed by its ease-of-use. The Makita 9557PBX1 is not only simple with its controls, but it also comes with a Lock-On switch, which allows for a smooth and continuous operation.

Basically, you don’t have to worry about confusing buttons. This type of switch is much safer than the slider switches, whereby you don’t have to slide the batteries to switch the grinder off.

When it comes to compactness, the Makita 4½ Cut-Off angle grinder has an amazing grip, courtesy of its small diameter at the handle. This gives it enough control over vibrations.

With such grip and sturdiness, it’s no rocket science that the Makita 9557PBX1 is equally durable. That is, the grinder has a labyrinth design, whereby its motor and bearings have been sealed such that debris and dust can’t find a way in. 

Still on durability, the grinder boasts of aluminum casing, which withstands harsh treatments, thus boosting longevity.

Finally, we loved the fact that you can actually interchange between AC and DC power sources. There’s a switch at the side of the motor’s housing that allows to make the switch.

Pros

  • Features a powerful 7.5 Amp motor for higher performance 
  • Comes with a thick and high-quality cord to protect it from wear and tear
  • Labyrinth construction guarantees durability
  • Operates using paddle switch, which is comfortable and reduces risks of accidents coz there isn’t sliding of batteries to witch on or off

Being a cordless tool, you’d think that its performance wouldn’t be at par. You’re wrong. The tool performs with the same power and vigor as a corded angle grinder. And yeah, it’s a heavy-duty grinder.

What to Look For When Buying the Best Angle Grinders

After checking out the aforementioned best angle grinder reviews, and you still feel like you’re still grappling with which specific to choose, then it’s probably better to ask yourself a few questions.

You need to know your specific needs. Is it a grinder’s power that you are looking for? Or is it weight? Or maybe you just want something that has an average performance overall.

Well, let’s take you through some of the questions you may ask yourself before finally settling on one specific angle grinder.

  • What’s The Grinder’s Performance In Terms of Power?

This should always be the very first thing to check. Depending on the tasks at hand, you can either opt for heavy-duty grinders or lightweight options meant for basic DIY tasks.

Obviously, a powerful grinder means great performance. However, this isn’t applicable in all situations. There are some grinders that are installed with powerful motors yet their performance isn’t up to par, mainly because they vibrate a lot. 

Don’t just go ahead and buy an angle grinder simply because its motor power reads higher figures. Instead, it’s advisable to check out other features, like its vibration, blade size and RPM (revolutions per minute).

Still, it’s important to go with a grinder whose power is 6-amp or higher. Anything lower than that isn’t powerful enough, even for basic tasks. 

  • What’s The Blade Size? 

There are different blades for different materials, and for different cuts. Therefore, check if the grinder comes with different blade options. Some grinders even come without blades, whereby you’ll be required to buy separately - although this is very rare. So, be cautious.

When it comes to blade sizes, you need to know the kinds of materials you’ll be dealing with most frequently. For instance, larger-sized blades are good when cutting larger surface areas.   

On the other hand, smaller blades are great at cutting on small and tight spaces. If you’re still unsure, then you can always go with the 4½ inch blade, which is the industry’s average.  

  • What’s The Motor RPM?

A grinder’s RPM tells us the number of spins the blade is gonna make. The more the RPM, the better. Hence, it’s advisable to choose a best angle grinder that can spin as many revolutions as possible.

A grinder whose RPM is 11,000 is much better than a grinder whose motor can spin only 9,000 revolutions per minute. Higher RPM means the blade can cut tougher materials. 

  • Are There Any Available Accessories?

It’s a good thing if an angle grinder features extra accessories that help with its performance and efficiency. Some of these accessories may include guards, wrench, wheels, carrying casing, etc.

Such paraphernalia can come in handy when operating the machine, and thus offers better value for money.

Final Verdict

It doesn’t matter whether you prefer safety, a powerful grinder, durability, or you’re into precision and accuracy. This best angle grinder reviews has made things easier for you and summarized what’s perfect for your liking.

So, you can go ahead and pick what’s right for you, and break a leg with your grinding!
