Best Angle Grinder Reviews

There’s an Angle Grinder for Nearly Every Job and Budget

When we set out to determine the best angle grinder, it didn’t seem like a terribly difficult task. However, when we got our team together, it was quickly apparent that there are so many outstanding models out there.


Angle grinders make up a core tool class, and nearly every brand makes multiple models. We’ve done our best to narrow down our top recommendations based on the performance, features, and even price of these tools. However, this isn’t an exhaustive list of everything available. If you see a brand you like in our list, but not the exact grinder you need, take a closer look at their lineup and you might find exactly what you’re looking for.

Best Angle Grinder Overall

Hilti Nuron 22V Cordless 6-Inch Angle Grinder AG 6D-22

Best Angle Grinder Overall: Hilti Nuron 22V AG 6D-22

Why We Picked It

The Hilti AG 6D-22’s performance is excellent, with a brushless motor keeping the RPMs high even under heavy pressure.

Two innovations really set it apart from the crowd, though. 360° Active Torque Control senses if the grinder makes a sudden move in any direction and automatically shuts off.

Then there’s SensTech. Sensors in the handle can detect when your hand is on the tool, even when you’re wearing gloves. When your hand leaves, the motor shuts down. It’s the only grinder we’ve seen to effectively offer the convenience of slide switch activation with the safety of a paddle switch in one tool.

Between the performance, features, and design, the Hilti Nuron AG 6D-22 is the most impressive angle grinder we’ve ever used.

At the end of the day, the tool you pick up the most is the best for the way you work since you use it so much.

It has the performance (13-amp equivalent, 9000 RPM) and safety features we demand (kickback control and electronic brake) with the convenience of cordless operation.

One of the other things that sets it apart from high-performance grinders in its class is the ergonomics of its handle design. It’s a slim profile with a trigger rather than a paddle or slide switch, and it very comfortable to use.

Milwaukee M18 Fuel Cordless 5-Inch Angle Grinder 2882/2883

best Milwaukee M18 Fuel Braking Angle Grinder with One-Key Review 2883

Milwaukee’s flagship small angle grinder has outstanding power with the brake and kickback control we’re looking for. Capable of using 4 1/2 or 5-inch wheels, both versions have a top speed of 8500 RPM. A nice bonus is that it comes with a tool-free flange, so you can kick that spanner wrench to the curb.

Best Cordless Large Angle Grinder (7-Inch to 9-Inch)

Makita 40V max XGT Cordless 9-Inch Angle Grinder GAG10

best Makita angle grinde

Why We Picked It

Not many brands throw their hats into the ring in the cordless large angle grinder class. Among the major brands, your options are between DeWalt, Makita, Metabo, and Milwaukee. None of them are poor choices. However, our pick for the best cordless large angle grinder in Makita’s GAG10.

Using a single 40V max XGT battery instead of two 18V batteries for power, it has kickback and brake safety features, and adds restart protection. Additionally, Makita’s Autostart Wireless System automatically turns on your vac when you pull the trigger, making this an excellent option for concrete and masonry work in addition to standard metalworking.

On the performance side, expect to run 7 or 9-inch wheels up to 6600 RPM. The tool also has an isolated rear handle to help absorb vibration and reduce fatigue in your hand and arm.

Best Corded Angler Grinder

In order to get the kickback control and electronic brake we’ve been talking about, the best way to get them is with the electronic controls that come with a brushless motor. In recent years, a couple of brands have introduced corded brushless angle grinders that offer those additional safety features.

That’s a big deal to our team, plus you don’t have carbon brushes to replace. If those features aren’t a big deal to you, you might find the best corded angle grinder for you is something different than what we’re recommending.

Best Small Angle Grinder (4-Inch and 5-Inch)

Metabo HPT AC Brushless 5-Inch Angle Grinder G13BYEQ

Why We Picked It

Metabo HPT earns our pick for the best corded small angle grinder with its 5-inch AC brushless G13BYEQ. It uses a 12-amp brushless motor to spin the wheel up to 10,000 RPM and holds it well under load. The paddle switch and electronic brake ensure the motor stops quickly if your hand comes off for some reason, and it has the built-in kickback control we prefer on grinders.

Info To Know

  • Best for professional use
  • 5-inch configuration
  • 10,000 RPM

Best Medium Angle Grinder (6-Inch)

DeWalt Brushless 6-Inch Angle Grinder DWE43244N

Why We Picked It

For your medium size grinder, we like DeWalt’s 6-inch DWE43244N. It’s a corded paddle switch grinder that takes advantage of a brushless motor. As part of DeWalt’s Performance & Protect line, it has an electronic clutch with kickback control and an electronic brake.

For those of your working at height, there’s a lanyard attachment hook just below where the cord enters the housing.

Flipping over to the performance, the motor runs 13 amps and produces a solid 1800 watts of power with speeds up to 9000 RPM.

Best Large Angle Grinder (7-Inch and 9-Inch)

Metabo WEPB 24-230 MVT

Why We Picked It

When it’s time to go big, we prefer Metabo for the best corded large angle grinder. In particular, we like the WEPB 24-230 MVT for several reasons. This 15-amp grinder is well-built and can handle wheels up to 9 inches with speeds up to 6600 RPM. Even though it’s not a brushless model, it does have a mechanical disk brake that activates if the deadman switch is released, if the wheel binds up, or even in an unexpected power loss.

The “MVT” designation on this grinder stands for Metabo VibraTech and includes an internal dampening system along with a vibration reduction side handle.

We also really like the rat tail handle design. Grinders of all sizes can have pretty wide handles that small and medium-size hands have a tougher time with. Metabo’s rat tail handle offers a much more ergonomic grip to hands of all sizes.

Info To Know

  • Best for professional use
  • 9-inch configuration
  • 6600 RPM
  • 13.5 pounds
  • Available as a slide switch (W 26-230 MVT)

Pros

  • Advanced vibration control
  • Comfortable rat tail ergonomics
  • Outstanding power under load
  • Mechanical disk brake that also activates in a bind-up
  • 3-position side handle
  • Pivoting main handle

Cons

  • Brushed motor

Best Angle Grinder for the Money

Cordless: Ryobi 18V One+ HP Brushless 4 1/2-Inch Angle Grinder PBLAG01

Why We Picked It

Ryobi made a huge jump in performance with its HP Brushless line of cordless tools, and the paddle switch angle grinder of the group is no exception. Paired with a High Performance battery, the brushless motor is capable of 9200 RPM using 4 1/2-inch wheels.

This is one of only a few grinders with a tool-free wheel removal. Ryobi’s FixTec flange nut has a flip-up section you can grab and twist to loosen or tighten with your fingers. If the nut happens to be too tight, there’s a spanner wrench you can use as a backup.

Even though this model is more expensive than some of the more budget-friendly cordless options out there, its performance makes it an excellent value.

Info To Know

  • Best for serious DIY or occasional professional use
  • 4 1/2-inch configuration
  • 9200 RPM
  • 4.4 pounds (tool only)

Pros

  • Tool-free wheel changes
  • 3-position side handle
  • Excellent value

Cons

  • No slide switch version available
  • Limited wheel size compared to other small angle grinders

Price: $99.00 bare, $199.00 kit (1 x 4.0Ah High Performance battery)

Corded: Ridgid 8-Amp 4 1/2-Inch Angle Grinder R1006

Why We Picked It

Ridgid takes your basic grinder needs up a notch with its R1006. As our top choice for the best corded angle grinder for the money, this 4 1/2-inch paddle switch grinder is more powerful than entry-level options with an 8-amp motor producing an impressive 11,000 RPM.

Of course, this is a pick that’s all about prioritizing value, and Ridgid’s $49.99 price tag on this model ensures you get a lot of grinder for your money.

Best Angle Grinder Brand

Metabo

Best Angle Grinder Brand

You can ask professionals which brand makes the best angle grinder and you’ll get a variety of answers. When we look at the grinders consistently doing the toughest jobs, no brand shows up as much as Metabo. The quality of Metabo’s engineering and design, along with an incredibly deep line that covers the entire range of grinder needs, makes it a top choice time after time. They’re more expensive than many professional brands, but that’s what we expect at this level.

Best Angle Grinder for Masonry/Tile Cutting and Tuckpointing

If you’re going to cut tile, granite, or other masonry with your angle grinder, you need to use a dust shroud and connect a dust extractor. A collection system keeps the dust from getting into your lungs while also pulling it away from your cutline. Plus, that debris can cause havoc on a grinder that’s not set up well enough to deal with it.

There are several add-on shrouds you can buy that take the place of the grinder’s guard, but a ready-to-grind package is the way to go. Our top recommendation is Metabo’s T 13-125 CED Diamond Cutting System.

Specifically designed to work with diamond cutting wheels, the power plant is a 12-amp/9600 RPM 5-inch grinder. Its wheeled shroud glides easily over surfaces (they can be removed for freehand cuts) and it’s rail compatible for long, straight cuts. The set comes with Metabo’s excellent cutting shroud, which is removable if you want to use the grinder for traditional tasks.

Price: $485.00

Best Angle Grinder for Concrete Surface Grinding

Makita 5-inch Concrete Planer PC5010CX1

Similar to tile cutting, the best angle grinder for concrete has plenty of muscle behind it, a shroud to help collect the dust, and has the unlimited runtime of corded AC power.

Check out Makita’s PC5010CX1 for a 5-inch grinder with a concrete shroud as an all-in-one tool. Its 12-amp motor has 1400 watts of muscle and there’s a vibration-dampening spring system to make the job less fatiguing.

If you’re on the hunt for the absolute best in concrete cutting and polishing on an industrial level, take a look at what US Saws has to offer. The Mark III Dust Buggy is ideal for cleaning out joints. For floor prep, the TC-7 Stand-Up Edger lets you tackle the edges close the walls where your larger concrete polisher isn’t the best option. Incidentally, both use Metabo grinders to get the job done.

Price: $364.00

Best Angle Grinder Wheels for Wood Carving

Most people don’t think of an angle grinder for wood carving duties, but there are accessories out there specifically for that purpose. One of the most helpful is essentially a wheel with chainsaw teeth on the edge. You can also use flap disks just like you do for metal, and there are several other types.

Most of the wood carving wheels are 4 or 4 1/2 inches, so a small angle grinder is your best bet, and we highly recommend a model with kickback control. The trick here is to make sure your grinder isn’t underpowered since this can be a very aggressive application. If you have spare batteries and a rapid charger, cordless can be a convenient option. However, the unlimited runtime of a corded grinder is our preference.

If you don’t already have a grinder in mind, give Metabo HPT’s G13BYEQ a shot as our pick for the best corded small angle grinder.

Best Angle Grinder Wheels for Cutting Metal

Diablo X-Lock Diamond Wheels

The best angle grinder for cutting metal combines high edge speed with high torque to give you efficient, confident cutting. Once you have that, it’s all about the type of metal you’re cutting and choosing the right accessory for the job. After all, cutting 16-gauge sheet metal is a very different job than cutting cast iron pipe.

You have two major accessory options: abrasive wheels or diamond wheels. Abrasive wheels are significantly cheaper, while diamond wheels last much, much longer. If you do a cost-per-cut analysis, diamond wheels end up being a better value if you can manage the upfront cost.

If you prefer abrasive cutting wheels, we like the performance and life we get from Makita’s, and they have both standard and X-Lock wheels available. Another one to keep your eyes on is DeWalt’s Elite Series.

For diamond cutting wheels, it’s tough to beat Diablo for both standard and X-Lock arbors. We also use Lenox MetalMax diamond cutting wheels frequently.

Best Angle Grinder – More Options From Brands We Trust

Best Craftsman Angle Grinder

Craftsman’s CMCG451 is a 4 1/2-inch model that updates the CMCG450 and gets it into the Brushless RP line. The big difference is that it bumps up the speed another 500 RPM to reach a max speed of 8500 RPM.

It has performance primarily meeting the needs of serious DIYers and has a 3-position side handle with a spanner wrench that stores conveniently in it.

There’s no kit option if you’re in need of a battery and charger, but if you’re already on the V20 battery system, the $119 price tag isn’t bad at all.

Price: $119.00 bare tool

Best Flex Angle Grinder

Even though Flex has been around a long time as a brand, its 24V cordless system is one of the newest on the market. Their 5-inch brushless variable speed grinder doesn’t have a first-gen feel, though. With legitimate Pro-level performance and a comfortable design, kickback control reduces injury risk in a bind-up while the side handle absorbs vibration. It’s also the best value in the professional small angle grinder class.

This grinder is available with a slide switch (FX3181) or a paddle switch (FX3171). Flex also has a dust shroud and dust extraction guard set for those of you working with concrete and masonry.

Price: $179.00 bare, $249.00 kit with a 5.0Ah battery and charger

Best Greenworks Angle Grinder

Greenworks is quickly expanding its 24V line of DIY-focused tools, and the angle grinder that’s part of it is worth your consideration. It’s a 4 1/2-inch model with a max speed of 10,500 RPM. Although the motor is brushed, the price tag is very approachable and makes for an excellent DIY value.

Price: $79.99 bare tool, $109.99 kit with a 4.0Ah battery and charger

Best HART Tools Angle Grinder

While Ryobi was our pick for the best budget cordless grinder, HART Tools makes a great case as another high-value pick for DIYers with the HPAG25. Their brushless model boasts the same 9200 RPM as Ryobi and has a three-position side handle. The best part is the price—just $119 as a bare tool.

The downside is that it’s not sold as a kit with a battery and charger. However, you’re going to want more than just the grinder, so grab the brushless drill and impact driver combo to help you get started.

Price: $119.00 bare

Best Kobalt Angle Grinder

Kobalt’s top grinder is the cordless brushless KAG 424B-03. It’s a 5-inch model with a paddle switch design that covers all the basics you need with a couple of bonuses. It has a three-position handle and the spanner wrench stores inside the handle so you have it when you need it.

The biggest story for Kobalt is the performance. The brushless motor and 6-cell 24V max battery system run your grinder wheels up to 8500 RPM with plenty of muscle to back it up. It’s a good choice for serious DIYers or even value-minded Pros who need a grinder for occasional use.

Price: $129.00 bare tool

Best Ridgid Angle Grinder

Ridgid has several angle grinders to choose from with options on both the corded and cordless sides. If you want to stick with the convenience of cordless, the 18V brushless R86047 is a solid pick as an entry-level Pro option.

Upgraded with 25% more power than its previous version, this paddle switch model peaks at 9000 RPM and stops quickly thanks to its electronic brake. While its feature set is pretty standard, it has a tool-free flange so you can keep your spanner wrench in the drawer during wheel changes.

Price: $139.00 bare, $219.00 kit with a 4.0Ah Max Output battery and charger

Best Skil Angle Grinder

Skil makes corded and cordless grinders, plus a high-value bench grinder we really like. For angle grinders, our favorite is the PWRCore 20 brushless model. It tops out at 8500 RPM with performance that exceeds what most people expect from a DIY-focused model.

In addition to the standard features, a couple of convenient add-ons include on-board wrench storage and an included USB power adapter to convert your battery into a USB power supply.

Price: $149.00 kit with a 5.0Ah battery and charger

What is an Angle Grinder?

An angle grinder is a handheld tool that spins a wheel at a very fast rate of speed. Small models can run well over 10,000 RPM while large models might run closer to 6000 or 7000 RPM.

That may seem backwards, but it’s the edge of the wheel that does the work. A 10,000 RPM speed on a 4.5-inch wheel has an edge speed of 3750 feet per minute. A 9-inch wheel at 6000 RPM has an edge speed of 4500 feet per minute.

Not only do larger grinders have a faster edge speed, their motors have more torque. It’s a noticeable difference when you’re cutting thick steel or grinding welds.

The other type of grinder you’re likely familiar with is a bench grinder. The concept is similar, but the big differences are that a bench grinder stays in place, and it’s used almost exclusively for grinding down materials. An angle grinder’s ability to move to the work and use a wide range of wheel styles makes it a more versatile tool.

What is an Angle Grinder Used For?

As you can probably guess from the name, an angle grinder is used for grinding. That’s not all, though. It can also cut and abrasively scrape paint, rust, and other surface coatings. In the concrete industry, angle grinders take on the role of smoothing surfaces and channeling out mortar. In some cases, remodelers might use an angle grinder to remove grout between tile, but oscillating multi-tools are a more common option for that job.

While there are some specialties wheels for use with wood, angle grinders are primarily used for working with metal and concrete/masonry.

How to Choose the Best Angle Grinder

Choosing the right angle grinder for the job is mainly about size and performance. With three primary angle grinder classes (small, medium, and large), it’s all about which size wheel fits in the area you need to grind, cut, or polish.

When the wheel contacts the material, it then has to get the job done. An underpowered grinder might cut 1/4-inch steel plate or grind welds, but higher-performing ones are going to do it much more quickly.

From there, it’s about convenience and features. By far the most convenient way to go is to cut the cord and use battery power. The best cordless angle grinders keep up with corded models—even up to 9-inch models! The trade-off is a higher cost and limited runtime. On the other hand, electronic controls give cordless grinders some features that aren’t common on corded ones.

Here are some other features to look consider:

  • Electronic braking
  • Automatic kickback shut-off
  • Advanced vibration control system
  • Compatible shrouds for working with concrete/masonry
  • Brushless motor (on cordless and corded models)
  • Smart controls/tracking
  • Three total side handle install points

Angle Grinder Safety Tips

Angle grinders can spin up to 10,000 RPM or more. When something goes wrong on the business end, it can be catastrophic, sending shrapnel into your face and body, hurting bystanders, or damaging material and equipment around you. Here are some angle grinder safety tips to prevent it:

  • Always wear eye protection—no excuses!
  • Consider wearing a metalworking apron
  • Wear cut-resistant gloves
  • Never work without a guard in place
  • Use a braking grinder when you can
  • Get a grinder with kickback control
  • Consider a paddle switch instead of an on/off switch
  • Wait until the wheel stops moving before you set the grinder down

How We Make Our Choices

As we considered the dozens of quality grinders available, there were several things we prioritized to help us make our recommendations.


Performance

At the end of the day, performance is still the number one priority. We’re looking for grinders that have enough torque to keep their RPMs high and continue to work quickly when the going gets tough.

Size and Weight

When it’s an option, our team reaches for the lightest, most compact tool that still gets the job done with confidence.

Safety Features

Braking grinders with kickback control are two of the top safety features we look for. Any other innovations that improve safety also earn big bonus points.

Additional Features

After safety features, other design elements that make the job easier help improve a grinder’s overall score.

Price and Value

We’re big on value. It’s not about paying the least amount of money possible, it’s about getting the most you can from the angle grinder that fits the budget you have.
