1. Makita 9557PBX1 – Overall Best Angle Grinder

The Makita 9557PBX1 is not just powerful, but one of the few consumer-grade grinders that can effectively handle such power. Also, it’s designed for comfortable handling and has a paddle switch for safer operation.

What I Like About This Product

I’m a fan of paddle switches in power tools because they are safer and, at the same time, can be stressful for intense use, but they can be a lot to handle at times. Fortunately, this Makita grinder has a lock-on (dead-man) switch to keep the grinder running without having to press the paddle constantly.

Also, the free aluminum case is a good addition. It may not be the strongest material, but its foam insert does a good job preventing discs from breaking or cracking. That’s enough, in my opinion.

Furthermore, it would perform remarkably on any home project and small industrial projects without overheating quickly like most inexpensive grinders. Still, you should be careful not to get it overworked as it’s not an industry-grade grinder.

Last but not least, the Makita 9557PBX1 is a joy to handle. It’s lighter than most in its category and has a sleek barrel that’s easy to grip.

What I Don’t Like About This Product

The free tool case is likely to be delivered with a dent or some form of damage to it. Nonetheless, it protects stored wheels effectively.

Aside from this, some folks may be frustrated by its auto-on switch because it disengages easily. Also, as opposed to how it’s advertised, it only supports a 5/8” arbor wheel and can’t switch between AC and DC.

Takeaway

Overall, if you’re a DIYer or pro (looking for a backup), the Makita 9557PBX1 is a great tool that gets a range of jobs done and will last for years if used appropriately.

Overall Rating – 4.6/5

2. Dewalt DWE402 — Runner-Up

Dewalt, like Makita, is a giant in the industry and known for serving customers with affordable and functional products.

The Dewalt DWE402 is a close competitor with our top pick, and it could be your #1 as it’s more powerful than the Makita.

What I Like About This Product

The DWE402 is remarkably powerful. Actually, it sits right at the top among 4 1/2” angle grinders as far as power goes. In fact, you can grind tough materials for long without it overheating. For a small angle grinder, it has more than enough power than you’ll ever need to get a job done.

Furthermore, you can swap wheels without a wrench using its spindle lock switch. Another handy switch is its lock-on feature that prevents the grinder from powering on by accident, and also, enables it to run without holding down the paddle switch.

Finally, the wheel guard is capable of rotating 360 degrees, which comes in handy if you need to work at awkward angles. Moreover, if you like, you can opt for the DWE402K model that comes with a tool case.

What I Don’t Like About This Product

The size of the Dewalt DWE402 is a hit or miss. For one, it’s heavy, and this can help stabilize the grinder while working on rough surfaces. On the other hand, it would cause fatigue pretty fast if you are going to be holding it for long.

Besides, it’s also somewhat large, making it hard to grasp fully or comfortably while depressing the paddle switch for most folks. So, if you don’t have giant hands or something close, it can be difficult to handle.

Takeaway

Without a thought, you should go for the Dewalt DWE402 if you’re looking for the most powerful 4 1/2” angle grinder that won’t fry up under heavy use.

3. Milwaukee “Fuel” 2780-20 M18 — Best Cordless Angle Grinder

The Milwaukee M18 has earned as the best and only cordless angle grinder in this review for its premium quality. It’s a trailblazer in its category that delivers close to the performance of corded grinders.

What I Like About This Product

Right off the bat, it’s easy to conclude that the Milwaukee 2780-20 is durable – and it truly is.  Plus, it built with ergonomic features like vibration reduction tech and a rubberized grip, which are only found in elite angle grinders.

While it isn’t the tool for heavy tasks, like cutting or grinding hard steel or concrete, it is a powerhouse in its lane. In other words, you can rest assured that it’d last long (on small projects), thanks to its brushless motor and Red Link + feature. This feature acts like a brake/clutch that shuts off power to prevent damage to its motor.

What I Don’t Like About This Product

The single most difficult issue with the Makita Fuel is its battery consumption. Maybe that’s why it’s nicknamed “Fuel” because it can go through a lot of batteries if you intend to do any intensive grinding job.

Moreover, its safety guard is quite too large for some users. And, the safety lock on the paddle switch is clumsy, but then again, it’s only to some users.

Takeaway

If you want a break from corded angle grinders or have a small project where it’s hard or impossible to plug into an AC outlet, consider the Makita 2780-20 M18 cordless angle grinder.

4. Black & Decker BDEG400 — Best Budget Buy

The Black and Decker BDEG400 is a masterpiece for entry-level hobbyists or anyone on a budget. By masterpiece, it means it’s affordable, functional, and very handy, way better than many expensive models.

What I Like About This Product

For a cheap grinder, I’m impressed by its 3-position side handle. This simple feature can up productivity by a notch, especially when cutting. The vertical (third position) allows you to put enough pressure on the workpiece.

The BDEG400’s performance is something to write home about. It works smoothly for all jobs around the home and occasional use in a workshop. For this reason, I don’t agree that it’s weak, as many reviews have claimed since it’s a cheap entry-level tool in the first place. So, it shouldn’t be used for heavy work.

What’s more, it’s a good option for folks who have small hands or find it hard to grip other models.

What I Don’t Like About This Product

The power switch is flimsy and too “plasticky,” which makes it hard to operate. Agreed, “you get what you pay for,” but it shouldn’t be a pain in the neck to switch the grinder on and off, and for safety reasons.

Takeaway

Overall, this is a great angle grinder tool for anyone looking to get a backup, finish a job, or for occasional use at home. It is affordable and delivers fast.

Overall Rating – 4.4/5

5. Porter-Cable PCEG011 4 1/2” Angle Grinder

Another inexpensive option, the Porter-Cable PCEG011, is a lightweight angle grinder that’s packed with user-friendly features.

What I Like About This Product

It’s a full package of all you can ask for in a grinder. The motor/speed ratio is amazing, maybe even too much for its cheap housing. Regardless, it can power through any material without damage as long as it isn’t bulky or too hard.

I’ll always cherish an angle grinder that has a 3-positon side handle and the PCEG011 one of them. It also has a spindle lock on top of the grinder for a hassle-free guard change and without wrenches.

What I Don’t Like About This Product

The PCEG011 is a fantastic grinder, but its power is way too much for its cheap plastic housing. It can get unbearably hot if it’s used for too long, and that will most likely, smoke/burn the motor as soon as on the first use.

Another drawback is its spindle lock. Many users have complained about the spindle lock button warping easily

Takeaway

All in all, it’s a good budget grinder for anyone looking to carry out small tasks in a swift fashion. Anything other than that, and its motor may smoke or overheat if it runs for too long.

Overall Rating – 4.3/5

6. Bosch 1375A 4 1/2`” Angle Grinder — Durable Inexpensive Option

Bosch is a widely known brand across several industries, most notably for its top-quality products, regardless of price.

The Bosch 1375A angle grinder is a testimony to this legacy. It’s inexpensive but built to last and function, which could have easily made it the top budget pick in this review.

What I Like About This Product

As I’ve mentioned earlier, the Bosch 1375A has an astonishingly solid frame for a “cheap” angle grinder. It doesn’t look or feel like a toy, as with most cheap angle grinders on the market.

Also, it’s powerful enough for almost most grinding operations but not on a large scale. As a reminder, it’s likely to overheat or burn out if used for anything other than that, just like all angle grinders in its price range.

On the flip side, I like the Bosch Service Minder brush feature. It stops the brush automatically when maintenance is due to increase its longevity.

What I Don’t Like About This Product

Although the exclusion of the spindle lock feature in the 1375A can be overlooked, but not the unfitting wrench for skewing the tool guard.

Not like a slide switch system is totally bad for safety, but the one sported on this grinder is somewhat flimsy. In short, you may have a hard time holding it up, but then, it has a lock-on feature that makes it manageable.

Takeaway

Like the rest of the budget options in this review, the Bosch 1375A is lightweight, handy, but even better, a rugged choice for homeowners and DIY enthusiasts.

Overall Rating – 4.3/5

7. Makita GA7021 7″ Angle Grinder — Best 7- inch Angle Grinder

It may seem biased that the top pick for 7” angle grinders is also a Makita, but it’s not, at all. It’s easily the most popular in its category, which, of course, is for good reasons, such as its sheer power and ergonomic features.

What I Like About This Product

Makita, as usual, does a good job of protecting the motor and inner components of the GA7021 from dust and debris, which can shorten its use cycle. The motor is sealed with their signature zig-zag seal, and the inner components arranged in a labyrinth construction.

The power rating and torque of the Dewalt are unrivaled compared to its closest competitors. Its 16 amp motor is more than enough to support 6,600rpm effectively. In turn, you get to grind and achieve faster material removal without unnecessary pressure and grind for hours on end.

Another elite feature you stand to enjoy is its adjustable handle. The handle where the paddle switch is located can rotate to the left or right, and the side handle in three directions. This makes it easy to work at awkward angles or tight areas and support its heavyweight in a comfortable position.

What I Don’t Like About This Product

It’s a fantastic 7” angle grinder that’s close to being flawless. Most issues with this grinder were personal, or technical, like late delivery, or having to purchase an inner flange for flat center wheels.

Takeaway

The Makita GA7021 7” angle grinder is built to last, and easy to handle, and most importantly, powerful. The perfect combination for a DIY person or professional looking to work on a large project or grind off material as fast as possible.

Overall Rating – 4.7/5

8. Metabo WEV 15-125 HT 600562420 5” Angle Grinder — Premium Variable Speed Angle Grinder

Putting the overly numerical model name aside, it is a premium quality grinder, and from a respectable brand — Metabo — that manufactures in Germany. It is the only 5” grinder in this review and the only elite variable speed grinder in this review.

In short, Metabo grinders are rated as one of the best worldwide by merchants, and this model maintains that rating for many reasons you’ll soon discover.

What I Like About This Product

Right off the bat, you can assert that this grinder will be a beast in your workshop. Its housing looks like it was carved out of stone, and the feel of the grinder breathes quality.

That aside, it possesses insane power and torque that can burr through even the toughest steel pressure and not bog down. Better yet, you can control its speed for increased efficiency and accuracy on softer or harder materials.

Meanwhile, it has a torque-limiting clutch that helps to minimize the possibility of a kickback when you jam discs unexpectedly.

Finally, it’s highly customizable, which makes it suit your taste better. For instance, you can buy a front handle, or an adapter that fits 6” grinding wheels, and more.

What I Don’t Like About This Product

All in all, it’s a great grinder with most of its drawbacks being personal ones. But I’ll say, for an elite grinder, it should come with a paddle rather than slide switch.

Takeaway

Overall, this is one of the most powerful grinders in this review, has a variable speed, and is built to last years of use. So, if you are in the market for a durable and controllable grinder for welding, masonry, or any profession, this is a great choice.

Overall Rating – 4.6/5

9. Metabo 606467420 Angle Grinder — Best 9” Angle Grinder

Another top-notch grinder from Metabo. This time, it’s a massive 9” angle grinder that’s suitable for heavy work, large grinding applications, or marathon use.

What I Like About This Product

Like the previous Metabo angle grinder we reviewed, its performance is well-tested and measured by professionals – the only product with this extent of transparency online -. Its torque rating is over the roof (150 inches to pounds), and with load, it’s speed maintains 4,600 rpm. This may seem meager if you aren’t familiar with technical ratings, but this is really impressive, such that it will grind any material without a problem.

As you’d expect, a grinder with its power and class would have good dust management for longevity. It uses Metabo’s trademark dust protection, and an auto-stop carbon brush to protect the motor.

Also, it’s integrated a patent vibration damping system that makes its enormous power possible to handle comfortably. Besides, its main handle and side handle (3-direction) can both be adjusted for better handling while working.

What I Don’t Like About This Product

It’s a big tool built to work on large and tough surfaces, like thick cast iron, or concrete. For this reason, it’s not a surprise that it’s quite heavy, but just so you know, you’ll have to work with over 12 pounds in your hands for however long you intend.

Takeaway

Surely, anyone shopping for the best 9” grinder would be looking for a tool with immense power and torque for fast material removal, and comfortable handling to work long hours. Well, the Metabo 606467420 has a built-in 15 amps motor, vibration protected handles, and a comfy paddle switch – the perfect combo.

Overall Rating – 4.8/5

10. Toolman 11500BPM 4 ½ Angle Grinder — Cheapest Variable Speed Angle Grinder

The Toolman 11500BPM an excellent budget option for those who want to work with a variable speed angle grinder.  It offers speed change within six levels and comes with, perhaps, the most amount of free grinding wheels you’ll ever see around.

What I Like About This Product

Without any doubt, its variable speed is a handy feature but can also make or break the user experience. For the most part, it’s awesome for tasks that require low speed, like polishing tiles or sanding, but not the best for power cutting and grinding.

Whether the price for the free grinding wheels was inclusive in its total price or not, it seems generous to give out 10 pieces at a time. This way, you can get to work as soon as you receive the package.

Although it doesn’t have a tool-less adjustment system, its spindle lock makes it easy to swap wheels with one wrench instead of two.

What I Don’t Like About This Product

It’s easy to tell that it’s cheaply made. And to make things worse, it constantly heats up, and the manufacturer only advises that you wear thick gloves on every use as a remedy, not even for protection.

Takeaway

The variable speed setting on these angle grinder is useful for anyone that needs it, and it’s probably the only reasonable budget option on the market. For the most part, it’s great for sanding and polishing fragile materials, like tiles.

Overall Rating – 4.2/5

How To Buy The Best Angle Grinder

Before picking a product, it’s only normal that know a thing or two about before you give up your hard-earned cash. For this reason, I’ll walk you through the functions, safety precautions, and features you should know before buying an angle grinder.

What Can An Angle Grinder Do?

Affirmative, an angle grinder is versatile. But what exactly does it do?

First, if you didn’t know already, angle grinders use compatible with several types of wheels that make them complete an array of tasks. This can include cutoff discs, abrasive grinding wheels, polishing pads, and more. Secondly,  the extent to the versatility of an angle grinder depends on the availability of wheels for its size, with 4” and 4 ½” wheels being the most versatile of all the sizes.

Cutting

This is arguably the most popular use of an angle grinder. Regardless of the speed of the angle grinder, it will cut through metal bars and tubes, tiles, or concrete, cleaner and faster than a hacksaw or any other manual option.

Sharpening

Sharpening is a simple and yet valuable function of the angle grinder. It saves you the space and cost of buying the best bench grinder separately to sharpen your blades. If you are wondering what are the uses of bench grinder then its definitely not portability.

An angle grinder can efficiently sharpen tools, like hoes, axes, ice scrapers, lawnmower blades, knife and so on. However, make sure you use a grinding disc rather than a cutting or wire wheel if you ever want to try it.

Cleaning Rusty and Rough Surfaces

Like I’ve said earlier, it’s all in the “wheels” (attachments). An angle grinder that’s fitted with a wire or brush wheel can get rid of rust on metals, or caked-on cement on tools and without hassle.

Repointing or Mortar Cutting

Repointing the old-school way with a chisel and hammer is a whole lot of work and takes time.

An angle grinder fitted with the right wheel (Diamond tuckpoint blade) will make short work of cutting out mortars. This saves you time and energy, which in turn makes your work more productive. It’s also good for polishing a plethora of materials, like stone, concrete, and so on.

Necessary Safety Precautions While Using an Angle Grinder

Safety can’t be stressed enough when using power tools, and it’s no exception with angle grinders. Angle grinder discs run at high speed and can recoil at the slightest slip-up, which can cause damage in the workshop or, worse, severe injuries.

Here are safety tips you should abide by when using an angle grinder:

1. Always Wear PPA

Wearing personal protective gear ( ) is essential while working with even the smallest power tool. To be fully prepared for any mishap while using the angle grinder, always wear:

• Face shield
• Work gloves
• Overalls or clothes that can protect your skin from sparks and debris
• Boots

2. Clear Your Workspace

An easy and totally free way to prevent accidents with the grinder is to keep your work environment safe. A good way to start is by arranging any dispersed, wood, metal, wires, or other materials that could cause a fall. Also, ensure that you only work in a well-lit space no matter what.

Last but not least, tuck away all flammable items.

3. Scrutinize All Attachments and Discs

Before mounting a cutting or sanding disc to the grinder, make sure it’s safe to use. To do this, check for cracks or wear on the discs, and if there’s a fault, never try to manage. Toss it in the trash can.

4. Use the Guard Always

Sometimes, you may be tempted to take off the blade guard to reach awkward angles or tight spaces. While this may work, it is utterly dangerous, and you should never form the habit, and kindly stop it immediately if you have.

5. Inspect the Inspectable

For starters, always ensure that the grinder is unplugged before changing discs. Also, check to see if the side handle is firmly attached or that the piece you’re working on is tightly clamped.

Features To Consider Before Buying an Angle Grinder

If you can’t make heads or tails of an angle grinder, it’ll be difficult to pick a model that fits your usage without overspending, underpaying, or worse, choosing a tool that won’t work at all.

Here are features you should consider when buying an angle grinder:

Power and Speed

When choosing angle grinders, power and speed are co-dependent metrics that determine how efficient and fast an angle grinder can work.

First off, most good angle grinders will run at an average 5,000 to 12,000 revolutions per minute and have a motor within the range of 5 to 12 amps.

Now, you’d think that a higher motor power (amps) would equal better performance, but that isn’t always the case. What most people don’t realize is that a higher power can easily cause overheating, which can shorten the grinder’s use cycle by a mile. So, what then?

As long as the high power of the grinder is matched with a good ventilation system, you would have no issues. But this is mostly seen in industrial-grade angle grinders, which are definitely much more expensive. Fortunately, most of the angle grinders in this review are affordable and have a system in place to protect the motor from overheating.

Power Source

Angle grinders can be powered in three different ways:

1. Electric
2. Pneumatic or air-powered
3. Battery

Pneumatic air grinders require an air compressor to function, which is expensive to run and stressful to move or carry around if you work on sites. However, they are usually more powerful than their electric or battery-powered counterparts.

A battery or cordless air grinder has one unbeatable edge over other types, which is mobility. It can be used anywhere, which comes in handy in remote areas where there’s no electricity, and stress of pneumatic grinders or tangled cords of an electric one.

Last, and definitely the most popular, are corded or electric angle grinders, which are the most affordable. They are relatively faster and more efficient since cordless grinders lose juice as the battery drains. Of course, there are some drawbacks to using an electric grinder: it’s limited to a place with an electrical outlet and its cord length, and it’s the least durable.

Disc Size

Fundamentally, a larger disc size would mean a more powerful angle grinder. But the thing is, disc size also restricts versatility.

The most popular and versatile angle grinders use a 4 1/2” disc size. They are great for DIY enthusiasts and can get any work from cutting to polishing done.  The reason isn’t so far-fetched: they are cheaper and compatible with the most variety of wheels, which are also readily available.

On the other hand, if you want to use the grinder for only heavy grinding jobs, a 9” grinder is the most suitable, with 7” grinders in second place.

Ergonomics

Subtle features in the design of an angle grinder can affect your efficiency and general satisfaction with the tool. Yet, many folks focus on power, forgetting that efficiency is the main aim of using machines.

Lucky for you, I’ll reveal some subtle features you shouldn’t miss out on. They include:

• Multi-directional side handle. The 3-way adjustable handle works the best, as you can position it vertically to cut more efficiently.
• Spindle lock
• Flexible guard locks to ensure safety and versatility while grinding
• Lock-on/off button to run the grinder without depressing the paddle or switch.
• Flat or recessed locking nut to fit thin cutting wheels

In the end, picking the ergonomic features will be based on your personal preference.

Dust Management

Within the course of use, angle grinders will generate a great deal of dust that can get into almost anywhere. This can make the motor burn out pretty fast, so it’s pertinent that your selected grinder has a form of dust protection, like a sealed motor.

Ignition Mode

When switching on a basic angle grinder, the force of its powerful motor might cause it to jolt aggressively in your hands. A “soft start” ignition feature cancels this out by letting it pick up speed in a steady fashion.

This feature is usually found in larger-sized or professional-grade angle grinders. So, it’s a plus if it’s sported on a smaller angle grinder.

Final Thoughts

Angle grinders are a handy tool for both professional artisans and DIY enthusiasts. They are perfect for grinding or polishing on most surfaces. They are also suitable for sharpening other tools at home or in the workshop. And they are great for cutting metals, wood, and tiles.

Nonetheless, you must choose a model that’s suitable for your work or level of expertise to get the best out of it. Fortunately, I’ve reviewed the best angle grinders on the market and how you can pick one that works for you.

Still in doubt?

Our top pick is the Makita 9557PBX1. It is powerful enough to work on most surfaces, easy to handle, and is manufactured by a respectable company in the industry. Most importantly, it can fit into your budget and even comes with a free toolbox and some grinder wheels.
