If you’re into metalworking, construction, or building things in general, you’ll definitely want to learn about the best angle grinder models available.

Angle grinders are also known as disc or side grinders. They use a round disc that spins at high speeds to remove material (grind), cut, sand, sharpen, or polish a variety of surfaces ( Source).

Portability and versatility are two of the most important benefits of using an angle grinder. You don’t have to remove objects that are bolted in place to work on them. Instead, you can take the tool to the object to cut, grind, polish, or sand it.

When shopping for an angle grinder, it’s advantageous to consider a few important variables. Grinder size is an important aspect. For example, a 4-½ inch grinder is ideal for smaller jobs like motorcycle maintenance.

On the other hand, a nine inch model is better for cutting concrete ( Source). Grinders range in size from four inches to massive 12 inch grinders made for industrial use.

Other important characteristics include safety features like automatic shut-off mechanisms, as well as engine size, torque, and whether your grinder is cordless or corded.

Below we expand on all this and more. Let’s dive into the most comprehensive angle grinder review and user guide piece published to date.

Top 10 Angle Grinder Models: Ranking Order

Below we will provide you with full reviews of the top 10 best angle grinder models, touching on our favorites features for each. But first, let’s take a quick look at the top 10 list.

How Do Angle Grinders Work?

Angle grinders are multiuse tools that can grind (remove excess material from a surface), cut, sand, and polish a wide range of materials. They feature a spinning disc, which varies in size and type depending on which function you’re using.

These discs spin super-fast, providing the power cut, grind, sand, and polish the densest of materials, including stone and metal.

How Much Do Angle Grinders Cost?

Angle grinder prices vary widely, with industrial models costing over $2,000 and decent home-use models costing as little as $30.

Price is certainly something you should consider when shopping for the best angle grinder for your unique needs. There’s no need to shell out a few grand if you just want to work around the house every now and then.

Reviewing the 10 Best Angle Grinder Models

Here we go; it’s time to dive into our reviews of the best angle grinder models on the market. We start with the German-manufactured brand, Metabo.

1. Metabo Quick Angle Grinder: Best Heavy Duty Angle Grinder [TOP PICK]

  • Made in Germany
  • World Class production facilities and techniques
  • Absolute focus on quality by our employees at every Stage of production
  • Manual, Hybrid and fully automated assembly systems
  • German engineering and ingenuity

Metabo grinders are manufactured in Germany. This is a vote of confidence because German engineering is considered to be among the best in the world.

However, a tool’s country of origin is irrelevant to us. We evaluate power tools by balancing the quality of their features, performance, price, popularity, and lifespan. Below are the variables that landed the Metabo Quick Angle Grinder at the top of our list.

Heavy-Duty Yet Compact

It’s hard to find a super-solid, heavy-duty angle grinder that is also compact and easy to use. But we found one in this Metabo model. It only weighs six pounds, which isn’t that heavy for an angle grinder.

However, its 1,700 watt Metabo Marathon-motor reaches a maximum speed of 11,000 revolutions per minute (RPM). It has the force of a larger, power grinder, and the compactness of a small grinder. This lets it provide some of the fastest, most efficient material removal available for a grinder in its price range.

Vibration Reduction

Metabo’s patented VibraTech anti-vibration system reduces emitted vibrations by 50%, making it easier to use. This significantly extends the lifespan of the Metabo Quick Angle Grinder and extends grinding disc life by up to 100%.

Superior Safety Features

A powerful machine should always include robust safety features. This Metabo includes a patented mechanical disc brake system that stops the disc from spinning within two seconds of turning off the machine.

Plus, its mechanical safety clutch reduces kick-back to the lowest level when the disc jams unexpectedly. Those are just a few examples; this grinder delivers are more safety features than we can list here.

2. Bosch 5 Inch Variable-Speed Angle Grinder: Best Variable Speed Angle Grinder

  • DUST GUARD: The Bosch GWS13-50VSP-DG Angle grinder and dust guard package delivers all-in-one solution that can help user move toward compliance with the OSHA silica dust regulation
  • POWER: Featuring a powerful 13-amp grinder motor, the GWS13-50VSP-DG angle grinder is able to produce up to 11,500 RPM. Along with that, the direct-motor cooling allows for higher overload capabilities
  • STABILITY: The Bosch angle grinder comes complete with a large, durable dust guard footplate to help increase stability during use for clean and accurate cuts. The included dust guard also features a single-screw depth adjustment
  • DURABILITY: Featuring carbon brushes to provide more durability than previous-generation brushes. The GWS13-50VSP-DG also comes complete with Bosch Service Minder brushes to let the user know when preventative maintenance is required
  • COMFORT: The tool also features Vibration Control with a two=position side handle while the paddle switch presents multiple, comfortable grip positions

Bosch power tools rarely disappoint, and that’s the case with the Bosch Variable Speed Grinder. Bosch is a household name when it comes to power tools. Below are a few reasons why this Bosch angle grinder made onto our list.

Variable Speed Control

We’ll start with its variable speed control since that was our deciding factor in ranking it second on the list. Variable speed control is just what it sounds like—the ability to shift between speeds while working a job. This is important when tackling complex projects; some projects are too much for a single-speed grinder.

For example, sanding paint is difficult if you’re using a single-speed grinder because higher speeds produce more friction. That friction, in turn, produces heat that melts the paint into the sanding disc. The ability to drop the Bosch Variable-Speed Angle Grinder’s speed as low as 2,800 RPM makes paint removal breeze. Plus, switching speeds is a seamless process for this grinder.

Built-in Intelligence

This Bosch’s motor features durable carbon Bosch Service Minder brushes. They alert the user when preventive maintenance is required, allowing them to replace the brushes before they start to fail.

Comfortable to Use

It also features a two-position side handle designed to reduce emitted vibrations. It makes the grinder more comfortable to use. This is a plus if you take on projects that require you to use the grinder for hours on end.

3. DeWalt (DWE402) Angle Grinder: Best Angle Grinder Under $100

  • Next Generation 11 Amp AC/DC 11,000 RPM motor of angle grinder provides the best power to weight/size ratio available
  • Dust Ejection System provides durability by ejecting damaging dust and debris particles that enter the metal grinder
  • Oversized brushes of this DEWALT angle grinder provide 2 times brush life over previous model (D28402)
  • Large spiral bevel gear provides long transmission life
  • One-Touch Guard allows for 360 degree rotation of the guard with a single action

It may seem hard to believe that a model under $100 landed at number three on our list. However, this DeWalt 4 ½ inch angle grinder is full of surprises. We found that out for ourselves in the workshop while testing it.

We even considered ranking it higher, but the two above won out in the end. Regardless, this affordable tool is among the very best angle grinder models out there, which is impressive considering its price tag. Let’s dig into why it ranked so high.

Robust Design

Price doesn’t directly align with quality and this DeWalt proves that. It’s on the heavier end of the spectrum, weighing 7.7 pounds. That’s heavy enough to withstand a beating, but not too heavy to use for an extended period of time. When you consider its physical dimensions (it’s not a large grinder) in relation to its weight, it becomes obvious how solid the DeWalt (DWE402) Angle Grinder actually is.

Grinding in Tight Spaces

This DeWalt is an average sized grinder when compared to many. Despite its solid construction and design, it still allows you to reach and use the tool in tight spaces. As mentioned above, not having to remove fixed objects to work on them is a major benefit of angle grinders.

Let’s say you want to cut something that’s screwed into the wall and all you have is a circular saw. It’s time to get out the drill, remove it, cut it, screw it back in, etc. Angle grinders allow you to squeeze into that tight space where the object is and cut it then and there. This DeWalt’s low-profile gear case makes that possible.

4. Makita 9 Inch Angle Grinder: Best 9 Inch Angle Grinder

  • Powerful 15.0 AMP motor delivers 6,600 RPM for faster material removal
  • Rotatable rear handle rotates with just the push of a button, with positive stops every 90 degrees, to suit most cutting and grinding operations
  • Wire mesh intake covers are engineered to prevent metal shards from entering motor especially when used in close proximity to other grinders
  • ""Tool-less"" wheel cover allows for easy guard adjustment with no need for tools to multiple grinding and cutting angles
  • Labyrinth construction minimizes dust and debris penetration into the motor and bearings for longer tool life

Coming in at number four on our list is a large, nine inch grinder from Japanese power tool producer, Makita. This Makita grinder is heavy, large, and it can slice through metal like it was warm butter.

Most users would never need a 9 inch disc grinder. Their disc capacity is simply too large for most jobs. However, some users do need so much disc space, so we began testing 9 inch models. When we came to the Makita 9 Inch Grinder, we knew we’d found the right one. We’ll explain why.

Taking on Large Projects

With its large disc capacity, this Makita 9 inch grinder packs a punch like Mike Tyson. Plus, it has the stamina of Cassius Clay.

When you use such a large grinding disc, each full 360-degree rotation takes more time. But the reduction in RPM is compensated for by the power you get from such a large grinding disc. It’s doubtful any other grinder on our list would get in the ring with this Makita hand tool. That’s because most models are 4.5 inch grinders—the Makita 9 Inch Grinder is twice their size.

Power Source Options

One interesting aspect of this grinder is that you can use it with alternating power sources. This is uncommon. It works equally well using an alternating current (AC) power source or a direct current (DC) power source.

5. Milwaukee Cordless Angle Grinder: Best Cordless Angle Grinder

  • PADDLE SWITCH: You can activate this grinder easily, even when you’re wearing thick work gloves, thanks to the paddle switch design
  • DEBRIS BAFFLES: An “L” shape molding near the grinding wheel picks up debris and prevents it from clogging up the tool’s internal components
  • TOOL-FREE GUARD: The guard is easily adjustable. All it takes is the push of a button, and you can have the guard adjusted for a variety of cutting applications at different angles
  • 3-POSITION SIDE HANDLE: Work with maximum stability with the help of the plastic handle, included in this kit
  • M18 COMPATIBLE: This Milwaukee power tool works with M18 18v lithium ion Milwaukee batteries. Compatible models include the 48-11-1860, 48-11-1850, 48-11-1828, and 48-11-1815, 48-11-1840, 48-11-1820

Milwaukee (officially, “The Milwaukee Electric Tool Corporation”) started producing tools in 1924. In that year, they introduced and started producing the first lightweight, handheld, quarter-inch electric drill. They’ve been making reliable power tools ever since, including this cordless grinder. Let’s dig into why the Milwaukee Cordless Angle Grinder ranked fifth on our list.

Power without a Cord

You may expect a battery angle grinder to be a little weaker than your average corded angle grinder. But that’s not the case with the Milwaukee Cordless Grinder. It delivers just as much power as mid-spectrum corded grinders. Its 4-pole motor puts out maximum power, whether you’re grinding, cutting, or sanding.

The advantage here is that you can walk 300 meters from your house and use your grinder. The disadvantage is that you can only use it until the battery runs out of juice. However, you can solve that problem by purchasing multiple batteries and carrying them with you.

Battery Compatibility

Officially, this model is called the “Milwaukee 2680-20 M18 18V Lithium-Ion 4 1/2 Inch Cordless Grinder.” We thought that was a little cumbersome, so we shortened it. Regardless, this portable grinder is part of Milwaukee’s M18 series of power tools, all of which use the same battery. Being able to take a battery from your drill and pop it into your grinder is quite convenient.

6. Metabo 5 Inch High Torque Angle Grinder: Best Angle Grinder for Concrete

  • Made in Germany
  • World Class production facilities and techniques
  • Absolute focus on quality by our employees at every Stage of production
  • Manual, Hybrid and fully automated assembly systems
  • German engineering and ingenuity

Powerful angle grinders can grind and cut through nearly any surface, including concrete. While some grinders can’t accomplish that, this Metabo concrete grinder can do it in its sleep. It features a 5 inch disc area and—like most Metabo tools—is solid, durable, and reliable. But that’s not all.

Impressive Versatility

Metabo is known as an innovative company that consistently introduces new technology into the market, driving more innovation from competitors. We can see that ingenuity here with features such as an advanced airflow system that keep the grinder cool. Also, this Metabo grinder includes quick-change wheels, tool-less disc change capabilities, and tool-less guard adjustments.


Just like the Metabo Quick Angle Grinder, this grinder is also very sturdy, durable, and can easily handle heavy-duty jobs. This grinder is relatively heavy, with a larger motor (1,500 watts) than most grinders its size. It can take more abuse than any other grinder we tested.

Standing up to Harsh Conditions

If you live in an area where weather conditions can become very harsh, this is a great grinder for you. Its “Long Life” 13.5 amp, variable speed motor can operate in a velocity range spanning 2,800 to 11,000 RPM.

The motor was designed to run like a champ in harsh conditions. That is why it provides up to 50% more torque than other grinders its size. The motor on this grinder is ideal for challenging projects that demand endurance.

7. DeWalt 5.3 HP Angle Grinder: Best Angle Grinder for Cutting Metal

  • High power 5.3 HP (maximum motor HP) and 6,000 rpm motor of angle grinder with overload protection provides higher operating speeds under load
  • Rotating rear handle provides improved ergonomics in cutting and grinding applications for the metal grinder
  • 5-position side handle of DEWALT angle grinder provides improved ergonomics for specific applications
  • Epoxy coated field and armature provide long service life against abrasion from airborne debris
  • Low-profile gear case allows for work in tight areas

Out of all the DeWalt grinders we tested, this metal grinder is the most powerful model DeWalt offers. It’s a beast and can tear through anything you place in its path. But it’s not just the sheer power that led us to name it the seventh best angle grinder available. Let’s elaborate.

A Hulk of a Grinder

This beefy hulk weighs over 16 pounds—that’s more than five times the lightest angle grinder on our list. That amount of weight helps stabilize the grinder when cutting through thick metal. Plus, this goliath accommodates either a 7 or 9 inch cutting disc, making it a versatile hulk of a grinder.

Moreover, it’s over 20 inches long if that helps drive home its bulkiness. If power and force are what you’re after, take a closer look to see if it’s a good fit for you.

Professional Power and Performance

As you might have gleaned from the above description of its size, this grinder was built for both home and professional use. It features unmatched power for a grinder of its size. Its 5.3 horsepower (HP), 15 amp motor can run a 9 inch blade at 6,000 RPM. Plus, it features overload protection, which guarantees faster-operating speeds, regardless of load size. The DeWalt 5.3 HP Angle Grinder gives you a smooth, highly accurate, and precise cut every time.

8. Bosch Angle Grinder 1375A: Best Small Angle Grinder

  • Compact: Weighing only 3.75 pounds, the Bosch 1375A Angle Grinder is lightweight, compact, and ideal for metal workers, vehicle fabricators, plumbers and other professionals who use grinders on a daily basis
  • Power: The angle grinder features a Powerful 6.0 amp motor to produce 11,000 no load rpm for professional cutting and grinding applications; The Efficient motor was designed with an extremely small field diameter, letting the user grind or cut with ease
  • Comfort: The 1375A offers a 2 position side auxiliary handle specifically designed to angle to a natural position for maximum operator comfort; The top handle of the angle grinder is also ergonomically designed
  • Convenient: The angle grinder also features Bosch’s Service Minder Brush System to eliminate guesswork and stops the tool when preventative maintenance is required; A 5/8 inches to 11 inch spindle works with a wide array of sizes, mounting the most popular accessories
  • Durable: The 1375A angle grinder features an epoxy coated design to protect the tool from abrasive debris; It was also designed with a sealed switch to keep dust and debris from entering the switch mechanism

Here is another Bosch model for you. It’s small and it’s inexpensive, but delivers a load of features and performs surprisingly well. When you see its price point, you’ll be shocked. Small doesn’t automatically equate to inexpensive, and we don’t think that’s the case here. This grinder likely delivers the most value you could get for your money when purchasing an angle grinder.

Compact Design

We didn’t call it the “best small angle grinder” without reason. This thing really is small. It weighs a meager 3.75 pounds and features a 4.5 inch disc area. It’s perfect for smaller jobs that require a smaller grinder.

Not Just for Smaller Jobs

Don’t judge a book by its cover. The Bosch Angle Grinder 1375A may be small, but so was Spud Webb (5’7”) when he beat Dominique Wilkins (6’8”) in the 1986 NBA Slam Dunk Contest.

This Bosch grinder showboats a 6.0 amp motor capable of reaching a maximum speed of 11,000 RPM. It truly is the Spud Webb of angle grinders. If you don’t believe that, order one and try it out—they’re easily affordable enough to purchase for a test drive.

9. SKIL 9296-01 Angle Grinder: Best Angle Grinder Safety Features

  • Powerful 7.5 Amp Motor with 11,000 RPM
  • Paddle Switch with no Lock-on: Preferred/Mandated switch at many jobsites
  • Heavy duty metal gear housing for added ruggedness and durability
  • Vibration-reducing handle with wrench storage
  • Tool-less guard for quick adjustments

SKIL is another household name when it comes to power tools. The brand produces many different types of tools and is best known for its high-quality saws. However, it also produces a high-quality angle grinder, which happened to land in our top 10 list. Allow us to explain why we like this model.

Safety First

That’s not SKIL’s official motto—I just made it up. But it certainly applies to the SKIL 9296-01 Angle Grinder. It features a non-locking paddle which instantly powers down the grinder if it is dropped or slips out of your hand.

Plus, it weighs less than five pounds, reducing the likelihood that it will slip out of your hand. It would be a great choice for beginners. We don’t say that because it lacks features—quite the contrary. We say that because it’s highly affordable and safe, with features that hold their own against much more expensive grinders.

Power and Price

This SKIL grinder is one of the three most affordable on our list. However, it’s a powerful grinder and, despite its price, it delivers impressive power output while in use. Its 7.5 amp motor reaches a top speed of 11,000 RPM and has the strength to cut through most materials, including metal.

10. BLACK + DECKER 4.5 Inch Angle Grinder: Best Budget Angle Grinder

  • Metal gear case for durability and longer life
  • 3 Position side handle provides added comfort and control
  • Spindle lock for easy accessory changes
  • Included Components: 4-1/2" Small angle grinder, Metal grinding wheel, Spanner wrench, Wheel Guard
  • Narrow body for comfortable grip

Of course, many of you know the Black and Decker brand name. You can find Black and Decker tools everywhere, from the kitchen to the workshop. The BLACK+DECKER 4.5 Inch Angle Grinder slipped its way onto the end of our list because of the reasons below.

Durable with a Long Lifespan

This Black and Decker angle grinder is constructed with a full metal gearcase. That makes the tool more durable than many of its peers and translates to a longer lifespan.

Price vs. Quality

Thousands of consumers enjoy using their Black and Decker grinder every day. Why? Because it is a high-quality product with a jaw-dropping price. It is backed by a two-year limited warranty, which validates the high-quality of this inexpensive tool.

Versatile, Comfortable, and Easy to Use

This grinder features a handle with three positioning options. You can set it to the left, right, or straight down depending on which position works best for you. This results in increased comfort and ease of use.

It’s a Powerful Little Guy

It is relatively small in size, with dimensions of 12.5 x 5.2 x 4.6 inches. It’s lighter than most but not amazingly lightweight at 4.5 pounds. In general, it’s a small grinder. But, that doesn’t stop its 6.0 amp motor from operating at a top speed of 10,000 RPM.

Choosing the Best Angle Grinder: Your Comprehensive Buyer’s Guide

Above we covered important aspects and features to look for when shopping for the best angle grinder. However, it’s helpful to have all that information in one place for reference. That’s why we created this guide—so you know what to look for and can find the best grinder possible.

Angle Grinder Discs

Disc size is among the most important features to consider when searching for the best angle grinder for your needs. The larger the disc, the deeper the cut you can make with your grinder.

Also known as “angle grinders wheels,” discs are measured by their diameter (using inches in the United States). Typically, you’ll see a grinder’s power increase alongside the size of its disc.

You can purchase a variety of angle grinder discs, and each one is used for a different purpose. Below, in our FAQ section, we cover what the most popular types are used for. But, to be thorough, below is a broader list of various types of grinder discs.

  • Abrasive grinding discs
  • Cut-off discs
  • Grinding stones
  • Wire brush wheels
  • Sanding discs
  • Polishing pads
  • Grit discs
  • Wood discs

No Load Speed

Here we’re referring to the speed—measured in RPM—your disc can spin while not in contact with any material. When in use, the resistance generated by the material you’re grinding, cutting, etc., slows the disc down. Then, the power of the grinder’s motor and the material you’re working on determines how quickly it can grind.

Generally speaking, slower speeds produce less friction-generated heat and are quieter. Faster speeds are louder and produce more heat. The ideal speed for any job is determined by the disc you’re using and the material you’re working on.

Power Output

The power output of angle grinders is normally measured in watts. Larger, heavy-duty grinders’ power output is also measured in horsepower. Moreover, corded, electric angle grinders often measure power output in volts, while battery powered grinder models measure in amps. Logically, the higher the wattage, voltage, horsepower, or amperage, the more power the grinder puts out.

Variable Speed

Variable speed angle grinders are just what they sound like: grinders with multiple speed settings to choose from. If you detect a burning smell, for example, it’s because you’re using a speed that’s too high for the job. Variable speed lets you avoid that and slow your grinder’s disc velocity to align with the material you’re working with.

Disc Guards

You guessed it; disc guards’ sole purpose is to protect you from the spinning disc, which can cause serious injury. Some models include a set disc guard, meaning you must use your tool from a certain direction in order to avoid injury.

What you really want is an angle grinder with an adjustable disc guard. These let you shift the guard around the periphery of the disc, enabling you to use it from any angle. It also reduces injury rates considerably.

Safety Features

In addition to adjustable disc guards, innovation from every direction in the market is driving more effective safety features. A few of those value-added safety features are described below.

You should always use caution while using an angle grinder; they can be dangerous tools. Digesting the information below will help prevent injury and ensure long-term future use of your grinder. Many of the best angle grinders today include at least a few of the features below.

Vibration Reduction
It’s easy to find grinder tools with built-in vibration reduction features. For example, a nonslip handle that’s designed to reduce vibration greatly improves your experience using your angle grinder.

More importantly, it makes the tool more comfortable and safer to use.

On/Off Locking

A lock/unlock feature lets users lock their grinder in the off position, which makes changing discs much safer. They can also use it while adjusting or moving their material in the middle of a job.

This prevents accidental start-ups that could cause serious bodily damage. This is ideal for longer projects because you can continue grinding for long periods of time without exhausting your hand.

Non-Locking Paddle Switches

First, if you don’t know, a paddle switch requires you to keep pressure on a lever for the grinder to function. They are also referred to as “Deadman Switches.”

If you’ve used a standard garden hose, you’re familiar with its handle trigger—when pressure is applied water comes out. But, if you drop it, you automatically release pressure on the trigger and the water flow halts.

Similarly, a paddle switch must be held down for the grinder to function. If you accidentally drop it, it shuts off automatically—in one or two seconds. Paddle switch grinders are best suited for shorter projects. Applying pressure for an hour is rough on your wrist and hand.

Brushless vs. Brushed Motors

For good measure, we’ll cover this topic, although many readers already know the difference.

Brushless Motors

They are powered by a closed loop of electric power and use an alternating electrical current to power the grinder. Brushless motors are newer technology—developed in the 1960s—meaning they are superior in certain aspects.

Advantages include more power output from less electricity, higher speeds, and less maintenance required.

Brushed Motors

Brushed motors were introduced in the 19th century and use a direct electrical current as their power source. They are still common today and are primarily used by larger machines like cranes, paper-producing machines, and steel mills.

Users can control their speed easily, meaning they are all technically variable speed motors. However, their brushes wear out and must be replaced periodically. This means more maintenance is required, which, in turn, means they are more expensive in the long run.

Angle Grinder Weight

The heavier your angle grinder is, the more challenging it will be to use it for long periods of time. The weight spectrum of angle grinders is broad. Our top 10 list features a lightweight grinder that weighs a mere 3.1 pounds—the Bosch Angle Grinder 1375A. On the other hand, the DeWalt 53 HP Grinder weighs 14.9 pounds (nearly five times as much as the Bosch).

Top Angle Grinder Brands

We mention this often, but “best” is a subjective concept thst depends largely on how you define the word and evaluate potential candidates. For us, “best” means looking for the ideal balance between features, performance, price, popularity, and lifespan.

Considering those variables, we feel the best angle grinder brands today are Makita, DeWalt, Metabo, and Bosch.

We won’t rank them from one to four and those names are not listed in any type of order. But considering the variables listed above, we’d call these four brands the best.

Makita has over 40 angle grinders on their website, ranging from small 4 inch grinders to the Makita 9 Inch Angle Grinder. The Japanese company has been around for nearly a decade and has become a master of power tool production.

It has production facilities around the world and brings in billions of dollars annually through global sales. The company clearly knows what it’s doing; in my time testing all types of tools, I am yet to meet a Makita that I dislike.

DeWalt is a major household name in the United States, and the only American brand out of these four. It dominates many markets in the US and carries a reputation for producing affordable, high-quality products.

Plus, it produces virtually every type of power tool that exists. Having been founded in 1924, it was then acquired by BLACK + DECKER in 1960. If you’re a B & D fan they by default you’re a DeWalt fan.

Metabo is a German-born brand, which coincidently was also founded in 1924. It is still based in Germany. However, the brand now belongs to Japanese power tool giant, Hitachi.

Post-acquisition, Hitachi decided to keep Metabo’s branding due to its reputation as a high-caliber manufacturer of professional-grade power tools.

Metabo sells everything from industrial-grade vacuum cleaners and air compressors to saws, drills, and angle grinders. If performance and quality were the only variables we evaluated on, we’d likely call Metabo the clear winner of the title, “best angle grinder brand in the world.” But their products are cost-prohibitive to many so we can’t.

Bosch is also a German brand and is the oldest of them all. The company was founded in 1886, by Robert Bosch, and has stayed in the family ever since. Unlike the other three, Bosch maintains a presence in various markets in addition to power tools. Over 60% of their total sales come from their mobility division, which produces hardware and software technology for vehicles and other transport mechanisms.

Frequently Asked Questions

What are angle grinders used for?

You can use your angle grinder tool for many things. However, they are primarily used for four types of projects: grinding, cutting, sanding, and polishing.

Grinding: People use angle grinders for grinding more than any other purpose. “Grinding” is the removal of excess material from a surface. Grinding requires a standard grinder disc. First, you grind the material, then use the grinder’s sanding feature to produce a fine, smooth finish.

Sanding: If you have ever used sandpaper you know how effective it can be. However, angle grinders can complete the same job with a sanding disc (also known as sander pads). But they are more dynamic than traditional power sanders. Just be sure any sander discs you purchase fit and are compatible with your grinder.

Cutting: Get your hands on an angle grinder cutting wheel if you need to cut through thick materials. You can use an angle grinder to cut through metal, ceramics, brick, various stones, concrete, glass block, and stucco, to name a few. They are often used instead of saws because of their maneuverability.

Polishing – Angle grinders’ discs spin at extremely high speeds. They are ideal for putting a shiny new finish on a variety of materials. Of course, you must use a polishing disc to accomplish this.

What is a pneumatic angle grinder?

Pneumatic grinders are smaller, lighter, use smaller discs that spin faster, and are meant for jobs that require maximum precision. We didn’t mention them above because, in essence, they are a different tool. They are also called “air grinders.”

To illustrate the size difference, check out the Ingersoll Rand 5102MAX Air Die (pneumatic) Grinder, one of the best available. It weighs 1.4 pounds, is 4 inches long, and reaches a maximum speed of 25,000 RPM. Compare that to the Metabo Quick Angle Grinder, which is 13 inches long. Then look at the Makita 9 Inch Angle Grinder, which weighs 14 pounds and tops out at 6,900 RPM.

What is a cut off wheel?

Cut off wheels, also known as parting wheels, are very thin, self-sharpening cutting discs used to cut through dense metal. They produce one of the finest cuts of any disc type available. Plus, they are available for standard angle and pneumatic grinders.

Can you break an angle grinder?

Using the correct disc and speed for the material you’re working on, you’re unlikely to break your angle grinder. However, if you’re using the wrong disc and speed for the material, the risk of breaking your grinder tool increases.

You’re more likely to break the disc than the grinder itself. But if the disc breaks, it’s likely to get jammed in your grinder while spinning at a high speed. That is the most likely potential cause of breaking your angle grinder.

Which safety precautions should I take when using my angle grinder?

Safety features alone aren’t enough to ensure your safety 100%. Users should take various angle grinder safety precautions when using their tool. The same goes for any power tool. Below are a few of the most important precautions to take.

  • Don’t wear loose-fitting clothing, jewelry, or any other dangling attire. A loose sleeve can easily be caught in your grinder’s moving parts, which will certainly cause injury.
  • Always extend your arms and hold the tool away from your body while in use.
  • Never operate an angle grinder (or any power tool, for that matter) under the influence of any substances.
  • Use both handles when grinding for increased stability and reduced risk of injury.
  • Wear appropriate safety attire at all times. This includes safety goggles, protective (tight-fitting) gloves, steel-toe boots, a hard hat, and whatever else might be necessary for the job you’re completing.
