The 10 Best Angle Grinders to Buy 2021

The 10 Best Angle Grinders to Buy 2021

An incredibly versatile tool, angle grinders put a tremendous amount of power into the hands of the wielder. These compact machines are designed to be used in a variety of construction tasks, making them a key inclusion in a contractor’s arsenal. Homeowners and hobbyists can also find a ton of utility in a grinder — really, the sky’s the limit in terms of its applications.

If you’re in the market for an angle grinder, we’ve put together this list of the best models available in 2020. Whether you’re a first-time user or seasoned professional, you’re sure to find the perfect model below.

What to Consider When Selecting an Angle Grinder

Before diving into our feature products, let’s go over some basic information regarding angle grinders. Keep these tips in mind as we move forward.

Types of Angle Grinders

There are three main types of angle grinders, each being optimal in different settings.

Corded Angle Grinders

Corded angle grinders are best for those who need their tool to perform on a high setting for as long as needed. These tend to be bigger and bulkier than their counterparts, and they also require you to be close to a power source at all times. Of course, the increase in power and sustained output is necessary in many demanding applications.

Cordless Angle Grinders

Cordless angle grinders are ideal for anyone who works on-site without constant access to a power outlet. These aren’t recommended for all-day use, lacking the same power and sustain as corded grinders. They also cost more in the long run, since the expensive batteries will need to be replaced eventually. However, the best cordless models out there can produce a surprising amount of power, and the absence of a cord makes for a more fluid workflow.

Pneumatic Angle Grinders

Pneumatic angle grinders are the least popular choice of the three. They’re lightweight and affordable, but don’t tend to offer the same level of quality as their counterparts. We would only recommend this option if you stock several other pneumatic tools in your kit, since it will help you get the most of your compressor.

Intended Use

Choosing an angle grinder ultimately depends on how you intend to use it. For example, a professional contractor will require more from their angle grinder than a DIY enthusiast.

If you’re looking for a key addition to your home tool kit, and would only need to use the grinder a few times a year, there’s no need to invest big bucks in a high-performance model — though it still might be fun to do so. On the other hand, if you plan on using the grinder every day — especially on tough jobs — you’ll need a machine you can rely on.

Regarding professional use, it’s important to choose the right type of grinder. An artisan doing stone work at a warehouse, for instance, needs a strong corded model that can be turned on all day without faltering. Alternatively, a contractor who repairs stone in residences will find all the power and sustain they’ll need in a good cordless model, with added portability and comfort to boot.

There are several other key features to consider when it comes to choosing the right angle grinder. Check out our full buyer’s guide below for a more in-depth look on the most important aspects of an angle grinder purchase. For now, let’s go over a few options.

Top 10 Best Angle Grinders 2021

1. Best Overall Angle Grinder DeWalt DCG413B 20V Max

DeWalt DCG413B 20V Max

Why we like it: Ergonomic, smooth and responsive, the DeWalt DCG413B 20V Max grinder is our best overall pick. It’s optimized for a wide array of applications, and its quality design and composition ensure that you can bank on its use for the long haul.

Editor’s Rating:

Quick Facts

  • Type: Cordless angle grinder
  • Intended Use: Professional and non-professional

Being a household name in construction equipment, it’s no surprise that DeWalt’s DCG413B tops our list. With its lightweight body, paddle switch and blade brake, this grinder successfully meets DeWalt’s sky-high performance standards. Its brushless motor guarantees a significant lifespan for the product, and it’s optimized to perform in a wide array of applications.

Being a cordless grinder, and with its modest 3.75-pound body, the DCG413B is easy to handle in tight corners. The design also provides a great amount of comfort even when used for long periods of time. This makes it a go-to solution for a number of trades. It’s no slouch in the power department, either, with its 850 W output and 9,000 RPM max no-load speed. In cases where the grinder’s function is challenged, its blade brake will engage immediately as the paddle switch is released, bringing the motion of the wheel to a full stop.

One small downside is that this is a baretool item, meaning that the battery and charger are sold separately. Still, even with the added cost, the overall quality on offer here is definitely worth the price. If you take good care of this grinder, it’ll do the same for you through many years of high-quality work.


  • Excellent quality and value
  • Ergonomic design
  • Blade brake optimized for safety
  • Fully portable
  • Powerful and versatile enough for most professional applications


  • Maximum output will quickly drain the battery.
  • Battery and charger sold separately

2. Best Premium Angle Grinder Metabo HPT AC

Metabo HPT AC

Why we like it: Metabo’s HPT AC angle grinder might be expensive, but the utility it offers makes it a great deal. This is the best machine for users looking for the highest possible performance regardless of the price tag.

Editor’s Rating:

Quick Facts

  • Type: Corded angle grinder
  • Intended use: Professional and non-professional

For those seeking the Ferrari of angle grinders, look no further than the Metabo HPT AC. Formerly known as Hitachi Power tools, Metabo is re-establishing its reputation as a provider of powerful utility. If performance and function are your top priorities, and cost economy is less of a concern, this is definitely the grinder for you.

The HPT AC brushless grinder is powered by a 12-amp motor capable of producing 2,800-10,000 RPM based on variable speed adjustment. Thanks to the brushless motor, you’re able to work using extra-long extension cords without experiencing much reduction in power. Even in tough applications like granite and metal modifications, the quality engineering of this machine allows you to work for hours without your tool’s limitations getting in the way.

We’re also impressed with the HPT AC grinder’s design and overall safety. The brushless motor allows for some reduction in the circumference of the handle, resulting in a very comfortable grip diameter. This reduces fatigue when working on a given task for hours on end. Additional safety features include a soft-start that reduces the load experienced at start-up, and kickback reduction which works to shut the power off should its wheel become bound. All in all, this is a wholly safe, extremely powerful and versatile machine. The only downside is its high price point — however, those willing to make the investment will be happy to receive the best corded grinder money can buy.


  • Powerful performance
  • High-quality construction
  • Comfortable to use
  • Great safety features


  • Expensive

3. Most Ergonomic Angle Grinder Bosch GWS18V-45

Bosch GWS18V-45

Why we like it: It’s hard not to become enamored with Bosch’s GWS18V-45. Thanks to its high-quality construction and excellent ergonomics, this is definitely love at first touch.

Editor’s Rating:

Quick Facts

  • Type: Cordless angle grinder
  • Intended use: Professional and non-professional

One standout feature of the GWS18V-45 is the great sense of control one feels when using it. This is accomplished in part by the two-position vibration control side handle and the cordless function of the grinder, resulting in a fluid workflow.

Along with its smooth handling, Bosch’s machine grants access to 10,000 maximum no-load RPM, making it suitable for a variety of tough grinding and cutting jobs. It also offers optimal safety thanks to its tool-less quick-change, burst-resistant wheel guard and restart protection. If that isn’t enough, Bosch also grants customers peace of mind with regards to longevity, with its signature Electronic Cell Protection and Electronic Motor Protection embedded in the machine’s engineering.

This model is sold in 4-½” and 5” disc size options. You’ll have to specify whether to include a battery with the purchase — if you do, expect the price to spike up significantly. Expensive batteries are a downside to all wireless power tools, including this one.

This is more significant to professional users, since regular battery replacement will result in a hefty annual expense. Its maximum output over time is also limited compared to corded models, though the same can be said of all cordless power tools. Ultimately, when powerful, portable use is a priority, Bosch’s GWS18V-45 is definitely a solid pick.


  • Amazing grip and overall feel
  • Portable and powerful
  • Reduced vibration
  • Great longevity


  • Batteries are expensive
  • Cordless function limits sustain

4. Best Angle Grinder Bundle Makita 9557PBX1

Makita 9557PBX1

Why we like it: Considering its low price tag, there’s a wealth of accessories included in the Makita 9557PBX1 bundle. The machine itself is powerful, safe and easy to use.

Editor’s Rating:

Quick Facts

  • Type: Corded angle grinder
  • Intended use: Professional and non-professional

Whether you’re a first-time grinder user looking for a full starter kit, or a professional who can use a few bonus accessories, the Makita 9557PBX1 includes a variety of goodies along with the grinder itself.

This package comprises a metal tool case, 5 4 ½” grinding wheels, cut-off and grinding wheel guards, a quality diamond blade with turbo rim engineering and, last but not least, Makita’s 9557PB angle grinder.

Those inclusions will set you up for a vast array of applications, providing you with a solid base kit that you can add to as needed. The grinder itself is quite powerful for the price, with 7.5 amps of power and 11,000 RPM delivery. It’s also easy to use thanks to its extra-large paddle switch and easy lock-on/off feature.

This grinder can get quite hot when used on tough applications or for long periods of time, which is important to keep in mind. We can’t find many downsides aside from that, especially at this price point.

Ultimately, there are more powerful grinders out there, like the Metabo 600380420 9-115 Quick. However, if all you need is a reliable, affordable grinder, this one is sure to do the trick. The extra inclusions don’t hurt at all, either.


  • Valuable accessories included in the bundle
  • Great price
  • Impressive power
  • Easy to use


  • Gets hot during prolonged or demanding use

5. Best Angle Grinder for Polishing DeWalt DWE 43113

DeWalt DWE 43113

Why we like it: With its awesome dust ejection system and impressive ergonomics, the DeWalt DWE 43113 angle grinder is the perfect tool for polishers. It’s backed by a 3-year warranty, so you’ll be covered if the machine ever underperforms.

Editor’s Rating:

Quick Facts

  • Type: Corded angle grinder
  • Intended use: Professional

Polishers find themselves in an intricate line of work that demands extreme attention to detail. Technically, all grinders have the capacity to polish, but we feel that DeWalt’s DWE 43113 has been built to give polishers everything they need to achieve a fluid workflow.

The DWE 43113 is well-balanced and easy to control, granting polishers mastery over any material they might encounter. It features an impressive dust ejection system that ensures good vision even when you’re working without proper ventilation. Its 13 amp motor, 1700 max watt output and 9,000 max no-load RPM provides all the power needed to polish virtually any material. If ever the tool doesn’t perform as expected, DeWalt provides a 3-year limited warranty, giving you plenty of time to troubleshoot should any issue arise.

You’ll need a hex wrench to swap between accessories on this model, and it’s unfortunately not included in the bundle. This grinder is also quite heavy, so even the most herculean polisher will need to take breaks in order to prevent fatigue. For polishers that don’t mind either of those downsides, this is sure to be a key addition to the toolkit. Alternatively, if you’re looking for a lighter tool to polish with, check out DeWalt’s DWE402 angle grinder.


  • Great dust ejection system
  • Powerful enough for use on all materials
  • Smooth and comfortable to use
  • Backed by 3-year warranty


  • Heavy
  • Hex wrench sold separately

6. Best Budget Angle Grinder Makita GA4530

Makita GA4530

Why we like it: Makita’s GA4530 angle grinder provides a surprising amount of power that far exceeds its price tag. Its compact design also makes it comfortable and easy to use.

Editor’s Rating:

Quick Facts

  • Type: Corded angle grinder
  • Intended use: Professional and non-professional

If you’re looking for the most bang for your buck, the Makita GA4530 is sold at a bargain rate considering the utility on offer. A major contributor to the construction industry, it’s no surprise that Makita would include such a cost-effective model in their range of grinders.

Despite its low price tag, the Makita GA4530 produces a tremendous 11,000 RPM, making it suitable for a spectrum of tough jobs. Keep in mind, however, that the motor doesn’t have the same sustain as other, higher-end models, so will begin building up heat and decelerating in RPM when used in demanding applications, such as grinding cement. It also lacks variable speed options, making it less than optimal for professional use.

All that said, this machine is still miles ahead of other angle grinders in its cost bracket. It’s a convenient pick-up for contractors who need an affordable grinder on short notice, or hobbyists who don’t require professional-level sustain. Its compact design also makes it quite comfortable to use.

We wouldn’t recommend going any lower than this price point unless you plan on using your angle grinder for occasional, light jobs — otherwise, you’d likely be compromising key features like safety and longevity. Thankfully, Makita’s GA4530 hits the sweet spot between quality and cost-efficiency. As an alternative option, the Makita 9557PBX1 angle grinder bundle is also extremely affordable and includes some valuable accessories with the purchase.


  • Very low price
  • Performance exceeds price bracket
  • Compact design


  • Overheats easily
  • No variable speed function

7. Best Angle Grinder for Hobbyists DeWalt DWE402

DeWalt DWE402

Why we like it: DeWalt’s DWE402 angle grinder packs a surprising amount of power given its light weight. It’s also sold at an affordable rate, and users can customize their bundle upon purchase.

Editor’s Rating:

Quick Facts

  • Type: Corded angle grinder
  • Intended use: Professional and non-professional

One would assume that the DeWalt DWE 402’s low price point would suggest low quality, but that’s far from the case. Packed within its lightweight frame is enormous performance potential, and its bargain price really lowers this model’s barrier to acquisition.

Despite weighing only 1 pound, the DeWalt DWE402 can run at 11,000 RPM. Such a high power to weight ratio is a marvel of engineering, and we highly commend the manufacturer for it.

DeWalt allows you to customize your purchase as you see fit, with bundle options that include Grounded, With Kit Box, With No Lock and Angle Grinder only. Included in all orders are a one-touch guard, two-position side handle and wrench.

Being so light, powerful and affordable, the DWE402 is a great choice for a spectrum of hobbyists — from homeowners looking to buff their steel staircase to stone carvers working on a marble statue. However, it isn’t the most practical machine to work with. For instance, changing the position of the guard can be difficult at times, which tends to slow the momentum of the task you’re working on.

The paddle is also uncomfortable to use, especially during long sessions. Still, such downsides can be expected at this price range. For a more fluid workflow, the DeWalt DCG413B 20V Max is definitely the way to go.


  • Fantastic power to weight ratio
  • Great price
  • Multiple purchasing options


  • Changing the position of the guard can be difficult
  • Paddle is uncomfortable to use

8. Best Angle Grinder for Quick Tasks Milwaukee 2780-20 M18 Fuel

Milwaukee 2780-20 M18 Fuel

Why we like it: For a cordless grinder, the Milwaukee 2780-20 M18 Fuel packs a decent punch. Its ergonomic design and impressive brake function also make for comfortable, safe usage.

Editor’s Rating:

Quick Facts

  • Type: Cordless angle grinder
  • Intended use: Professional and non-professional

For those seeking an angle grinder that will serve them well in fast jobs, Milwaukee’s 2780-20 M18 Fuel is a safe bet. It packs a surprising amount of power — more than enough to help you with quick grinding, sanding, cutting and finishing tasks.

The M18 Fuel has been engineered with the full force of Milwaukee’s world-class team, with optimized performance, electronic clutch and overload protection, resulting in a significant reduction in vibration upon use. This provides a great sense of control, which is further amplified thanks to the model’s comfortable grip. The brake feature is well-built, stopping all motion quickly and efficiently.

As an unfortunate downside, this option lacks some speed and power compared to some of the other cordless grinders on our list. It also has a relatively feeble battery life, so your work sessions will likely be short.

To buy some time, you can use large, high output batteries, though that would also increase the weight of the tool. Ultimately, if you’re looking for a grinder that will help make short work of quick tasks, this Milwaukee’s M18 Fuel is definitely worth considering. Alternatively, if you need a cordless angle grinder that can take on more demanding applications, check out the Bosch GWS18V-45 model.


  • Ergonomic design
  • Reduced vibration during use
  • Efficient brake feature
  • Decent power for a cordless grinder


  • Short battery life
  • Lacks speed

9. Best Angle Grinder for Tough Jobs Metabo 600380420 9-115 Quick

Metabo 600380420 9-115 Quick

Why we like it: This Metabo angle grinder is perfect for making quick work of tough jobs. The tool-free disc change also helps provide an optimal workflow.

Editor’s Rating:

Quick Facts

  • Type: Corded angle grinder
  • Intended use: Professional

As its name might suggest, the Metabo 600380420 9-115 Quick is a machine, sent from the future to make quick work of even the toughest jobs. A brand that’s known for pioneering professional tools, Metabo instills generations of German engineering and ingenuity into their products, and their Quick angle grinder is no exception.

Faced with the toughest of jobs, when other name brand angle grinders wear out, this one spins on. The immense power packed into its frame is enough to make smooth work of tough materials like concrete and steel.

Because the machine runs so well, even your wheels and bits will enjoy an extended lifespan. The workflow is also quite practical thanks to the machine’s tool-free disc change, which allows you to quickly swap between accessories without losing any momentum.

As an unfortunate aside, this model’s uncomfortable grip makes it quite difficult to use. The large caliber handle tends to cause fatigue in the hand quite quickly — obviously, that’s quite dangerous during tough jobs. Its sub-par ergonomics is a huge downside with Metabo’s machine — aside from its high price point — and it’s enough to knock it down to near the bottom of our list.


  • Powerful performance
  • High-quality construction
  • Tool-free disc change


  • Ergonomics are poor
  • Expensive

10. Best Angle Grinder for Beginners Black+Decker BDEG400

Black+Decker BDEG400

Why we like it: Black+Decker’s BDEG400 is very affordable, making it an easy pick up. It’s useful for short, easy tasks, though it’s not recommended for demanding applications.

Editor’s Rating:

Quick Facts

  • Type: Corded angle grinder
  • Intended use: Non-professional

In terms of price, it’s hard to find a high-quality, less expensive grinder than the BDEG400. Of course, the cost is only one consideration. While this machine works well on easy applications, its price tag is reflective of its overall build quality.

This grinder’s spindle lock allows for easy swapping between accessories, and the metal gear case ensures easy transportation. In the bundle you’ll find a metal grinding wheel, spanner wrench and wheel guard — inclusions that we definitely appreciate given the machine’s cost bracket.

At this price point, it goes without saying that the grinder should not be used for demanding applications over long periods of time. You risk damaging the grinder, and you definitely do not want to toy around with a grinder’s potential for causing injury should something go wrong.

We recommend this option if you’re a first-time user seeking a cheap, convenient grinder for use on quick, easy jobs. For everyone else, we’d definitely advise investing a little more into the purchase. Makita’s GA4530 model is a tad more expensive, but offers a considerable improvement in performance and safety in return.


  • Very low cost
  • Useful accessories included in bundle
  • Practical swapping between accessories


  • Low performance compared to other models
  • Can be dangerous if limits are tested

Guide to Buying the Best Angle Grinder

Now it’s time to look at some of the key aspects involved when choosing an angle grinder. If you’re new to the tool, there’s quite a bit to keep in mind, so let’s dive right in.

Features to Consider in Good Angle Grinders

Aside from the price tag, here are a few fundamental components to consider when picking the perfect angle grinder.


RPM (or revolutions per minute) is the metric that governs a grinder’s performance and power. The higher the RPM, the higher the potential of the grinder to successfully perform its task. Cutting applications require a much faster RPM than applications like scoring, sharpening, and polishing.

Higher RPMs also demand more experience from the wielder. There’s a risk of damaging the workpiece — or worse, damaging yourself — when not used properly. This is one of the reasons why variable speed is much appreciated in an angle grinder. It helps not only the amateur user, but also the professional who requires access to a variety of RPM settings in their work. Our best overall pick, the Dewalt DCG413B 20V Max, graciously comes with a variable speed feature.

Disc Size

Disc sizes tend to range between four to nine inches. Generally speaking, larger discs are used on more demanding applications, while smaller discs are better for precision. Professional users will likely stock discs in a variety of sizes, while DIYers will find most of the utility they need in a 4 ½” disc. The Makita 9557PBX1 angle grinder bundle comes with 5 4 ½” grinding wheels, which is more than enough to get you started.

Disc Guard

Disc guards are considered a must-have on angle grinders. They might impede your workflow depending on the angles you’re using, but working without one introduces too great a safety hazard.

Ideal models feature an adjustable disc guard that you can move and lock in at will. This benefits your production flow when there are tough angles to work into, as it eliminates the urge to remove the guard completely. The Bosch GWS18V-45 angle grinder features a burst-resistant wheel guard that will help keep you safe should anything go wrong.

Disc Brake

Disc brakes slow and stop the disc mechanism as the machine is turned off. Without it, the disc would continue to revolve at a high speed until it naturally comes to a halt. The disc brake is another necessary safety feature on an angle grinder, and we wouldn’t recommend any model that comes without one. With the Dewalt DCG413B 20V Max angle grinder, the disc brake is activated the moment the paddle switch is released, bringing the wheel to a quick stop.

Lock on/Lock off Functionality

An angle grinder’s lock on/lock off functionality is a bit of a divisive matter. It introduces a ton of efficiency at the cost of a significant safety risk.

The lock on/lock off functionality allows you to set the machine’s paddle in place so that the grinder can operate without you having to keep your thumb on the paddle. It’s optimal — and sometimes necessary — in tough, all-day applications, since keeping one’s thumb on the paddle while performing intricate work all day is likely to impact quality.

That said, it’s easy to see why this feature can be so dangerous. If something should ever go wrong, the grinder won’t turn off automatically when your thumb leaves its paddle. Despite the added utility, it’s important to recognize the tremendous potential of injury every time a grinder with lock on/lock off functionality is being used. Ultimately, we recommend sticking to manually operated grinders for all non-professional use. With DeWalt’s DWE402 angle grinder, you can customize your order to exclude the lock function.

Dust Sealing

All grinder users know that mounds of dust often go hand in hand with their tool. Quality grinders offer a dust sealing solution that prevents any dust from affecting the performance of the motor. This can come in the form of a seal or a strategic design that guides incoming dust away from the machine’s sensitive components. If an efficient dust ejection system is one of your top priorities, we recommend the DeWalt DWE 43113 angle grinder.

Angle Grinder Safety

Angle grinders are incredibly useful tools that put the power of modern engineering right in your own hands. They’re also one of the most dangerous power tools in existence — right up there with the table saw. Whether you’re a grinder master or first-time user, it’s important to constantly keep in mind the potential for fatal injury that comes with these machines. Here are a few tips to help keep you safe while at work.

  • Always wear the proper protective gear for the application in question, whether it’s a face mask, safety goggles, safety mask, spark-proof apron or all of the above.
  • Take time to declutter your workspace before getting started on your task. Remove any scattered tools and debris along with all lightweight materials like paper, as they can get swept up by the machine’s fan. It’s important to ensure an uninhibited workflow so as not to increase your risk of injury.
  • Ensure proper lighting in your workplace. Unimpaired vision is key in all grinder-related tasks
  • Adequate ventilation is equally important, especially when the task you’re working on is sure to kick up a lot of dust.
  • Before turning the machine on, take a moment to ensure that the disc is properly locked in place. If loose, the machine might eject the disc, which can be extremely dangerous when working with a high RPM machine.
  • When using a corded grinder, ensure that the cord is laid out safely, preferably away from areas with a lot of foot traffic.

In case you were wondering about something we haven’t covered so far, here’s a quick list of common angle grinder questions.

What Can Angle Grinders Be Used For?

Angle grinders can be used for a variety of fabrication and modification jobs like cutting, grinding, scoring, sharpening, polishing, finishing and deburring.

Can an Angle Grinder Cut Concrete?

Most angle grinders have enough power to cut into concrete material when using a diamond saw blade. However, it’s recommended that you use a lot of water when cutting concrete, since neglecting to do so will overheat the blade, possibly causing it to break. Most grinders don’t come with a water cooling component, so the task might require a special order or modification. Ultimately, the best way to cut concrete is with a walk-behind concrete saw.

Can an Angle Grinder Cut Steel?

An angle grinder is an optimal tool for cutting steel as long as it’s fitted with the proper disc. An abrasive metal-cutting disc will allow you to cut virtually all types of metal, though the disc will wear out quickly. An alternative option is a diamond blade that’s been rated to tear into metal.

How Do You Prevent an Angle Grinder Kickback?

Kickbacks are one of the most alarming aspects of using an angle grinder. One’s first instinct in this situation might be to let go of the tool completely — this isn’t advised, since there’s no telling where the grinder might land should you drop it. In the event of a kickback, keep a strong grip on the grinder’s body and side handle to maintain maximum control. Position yourself behind the rotating wheel, and switch the tool off.

For more information, check out this video on how to prevent angle grinder kickback.

Are Angle Grinder Sparks Dangerous?

Of all the dangers that come with using an angle grinder, sparks aren’t the most concerning, even though for novices they can be the most alarming. However, sparks can potentially be harmful, especially when working with metal. Sparks that erupt from cutting metal are molten hot and sharp, though they’re small enough not to pose an immediate threat. Always ensure that your sensitive areas (face, neck, limbs, etc.) are not exposed when working with sparks, and you should be just fine.

Final Words

Not all grinders are made equally, each of them being specifically suited to a user’s set of needs. Hopefully our list has given you an idea of the perfect angle grinder for you. We’ve done what we can — now it’s all up to you to find it. Remember that a grinder is not a toy, and you’ll need to keep your wits about you at all times when using one. Stay safe and sharp, and your grinder will do the same.
