Top 10 Reviews

The following is a list of the top ten angle grinders that are considered the best on the market today.

Best Pick: DEWALT Angle Grinder Tool (4 ½”)

This Dewalt is one of three angle grinders from the same brand we’ll be looking at. But each of them have their own differences (but plenty of similarities). But we digress.

This runs on 11 amps and has a motor that will allow the grinder to run at 11,000 rpm. If you are looking for a grinder tool that will give you plenty of power, then you might enjoy using this grinder tool compared to other grinders you may have used in the past.

This has a two-position handle which is perfect for ergonomically friendly operation. Not to mention, it will be easy to grip while you operate the tool and move through corners and edges. It’s one of the best grinders that you can find if you want something that’s professional grade for daily use or home improvement projects that come once in a while.

The one-touch guard will help keep your hands safe in the event of any slippage (which can happen at times). You can easily adjust the guard if it seems to get in the way of your project. But it’s better to be safe than sorry.

One of the best features that we like is the dust ejection system that will prevent dust and debris from clogging up the machine. This means you’ll have better reliability and a long-lasting angle grinder that will be great for use for years to come. If you want excellent operation, durability, and reliability then you’d be hard-pressed to find an angle grinder quite like this one anywhere else.

  • Powerful
  • Easy to adjust safety guard
  • Perfect size for portability and versatile use
  • Can last a long time
  • Dust ejection system does a great job of keeping out dust and debris
  • A little heavier than some grinders on the market

Angle Grinder Buyer’s Guide

If you are struggling to make a decision on an angle grinder, you are not alone. That’s why we put this buyer’s guide together so you’ll be able to whittle down a few options so you can choose one that will fit you best.

First, we’ll be taking a look at things to consider, followed by the pros and cons of angle grinders. You’ll be able to know some of the upsides and downsides of an angle grinder.

Things To Consider Before Buying

It’s always a good idea to take a few things into consideration. It will help you determine which grinder will be useful for your personal needs and eliminate those that don’t fit your criteria. Consider the following while looking for an angle grinder:


If you are on a budget, then you may look at the price first before anything else. Granted, there are some things you’ll need to look at beyond the price itself. Performance and quality should matter more. However, in the final analysis it’s all about finding the best that you can afford in terms of these qualities. Don’t go for cheap and sacrifice good quality and performance just because you want to save a few dollars.


Angle grinders come in different levels of amperage. Some will be higher than others. If you are looking for something that will give you a good amount of power for smaller projects, then you can settle for low amperage. Higher amperage would be perfect for heavy duty projects and even daily work for most contractors. Consider what your initial plan will be for angle grinders and you’ll find one that will match the level of power.

Cordless or Corded?

Angle grinders come in two different types: cordless and corded. The differences between the two are pretty self explanatory. But if you want more power, then corded is the way to go. If you are going cordless, you may want to consider using 3a or 4a batteries that are compatible with the grinder itself.

What will you use it for?

Grinders can be used for metalworking, plumbing, and even woodwork. You might also be a contractor that will be using power tools on a regular basis. Another question worth asking is: how often will you use it.

If you are looking to use it on a daily basis, a corded angle grinder might be something used for heavy-duty projects since they would require a lot of power.

If it’s for projects that can go on for a few hours (or less), a cordless angle grinder will be better. Keep in mind that grinders can be used for multiple purposes such as grinding and cutting.


Like the amperage, angle grinders have speeds. Some will run at a top speed of 12,000 rpm and others will run as low as 8,000 rpm. If you are looking for something that is considered professional grade, then you’ll want to go with a grinder with a faster speed. Lower speeds will be good for casual projects.

Pros and Cons

As mentioned, there are upsides and downsides to angle grinders. You need to know what to expect from them when you put them to use. Let’s take a look at the pros first:


  • Most have great ergonomic design: If there is one thing that is important for the user, it’s comfort. Most of the angle grinders are designed to make sure you are handling it properly so you are able to prevent any injury due to improper use.
  • Great for grinding and cutting: If you are looking for a power tool that will work as a powerful cutter compared to saws, then an angle grinder will be perfect. This has the ability to cut through various metals with ease (something most saws will fail to do).
  • Easily portable: Most of the angle grinders are small and compact in size. Therefore, it makes them easily portable. You can take this with you from one jobsite to the next if you are a contractor. After all, they are lightweight and come in sturdy storage cases. They are not like some power tools that are heavy and take up too much room.
  • Available in corded or cordless: Angle grinders can be used by way of electric power or battery power. Either way, they will be useful in some way. As mentioned, you’ll need to choose one or the other depending on how often you plan on using it and for specific projects.
  • Great safety features: Angle grinders come with a few great safety features. They come with guards and switch locks. This will help protect your hands from getting cut as well as accidentally powering on the switch and putting yourself in harm’s way.


  • You may need to purchase batteries separately: Some cordless angle grinders will come with batteries and others may not. Regardless, you may need to purchase additional batteries separately. One of the common shortcomings of these grinders is that it can drain battery life fairly quickly.
