What is the best angle grinder?
The angle grinder reviews below highlight the ten best options we’ve found. The products on our list are here because they excel at the attributes that are most important for a successful angle grinder. These include power, safety, precision, durability, and versatility.
What is the importance of angle grinders? In case you aren’t aware, angle grinders are among the most important welding tools that rarely miss in any serious metalworking shop. They are handheld devices that use their consumable discs to shape or cut metal, grind grooves, smooth a weld and remove rust from metal. Top Metal fabrication company Melbourne
When TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas) welding, the importance of working on clean, neat surfaces cannot be overstated, angle grinders help you smooth the surfaces, thus saving you hours of labour.
But, as you might be aware, choosing the right one is no walk in the park, especially for first-time buyers. You will need to consider several factors, such as whether you want a cordless or corded grinder, the revolutions per minute (RPM), the disc size, type of speed, the switch, and others. Worry not, though, we have got you covered!
In this buyer’s guide, we will highlight some of the leading products in the market and everything you need to be on the look-out for when buying one for your metal works.
Best Angle Grinder
DEWALT DWE402 4.5″ Angle Grinder – Best Overall
The DeWalt DWE402 is an impressively powerful 11-amp grinder that will be able to navigate both high-volume and precision work with ease.
It’s optimized to be compact enough to squeeze into tight spots, and even includes a handy dust ejection design that will help the motor hold up over time.
Safety is a consideration as well. The handguard rotates completely around the tool to give you complete protection from any sparks or debris that are kicked up while you work. You even get a hard case that will make it safe and easy to transport.
In keeping with DeWalt’s pattern, this is a pricey tool by angle grinder standards. The high levels of power might also be a little much for beginners. If you aren’t well-versed with grinders, you may over-grind the workpiece.
Angle grinders are a versatile power tool, essentially a hand-held bench grinder, used for polishing and cutting with an abrasive disc (also called a cutting wheel). The discs are interchangeable with either a wrench or a "quick change" setup, depending on the particular tool.
The type of disc determines the kind of work that can be done. For example, grinding discs can be used for removing excess metal from a welding and wire brush wheels can be used for polishing. Disc sizes can vary, but the common dimension is 4-1/2".
Standard methods of powering an angle grinder are corded and cordless. Air-powered grinders are also common.
Grinders are loud, produce sparks, and the discs can shatter. For these reasons, you should always wear appropriate safety projection, including earplugs, gloves, eye protection (safety goggles and/or face shield) and protective clothing. The project being worked on should also be held securely in place with either clamp or in a vice.
Milwaukee 2780-20 Angle Grinder
The Milwaukee 2780-20 has much in common with the DeWalt. It’s powerful, with an adjustable handguard, a hard-plated carrying case, and a special design to protect the inner workings from dust.
Our main concern about this tool pertains to value. It’s actually more expensive than the DeWalt, but it underperforms slightly in one key way. The components aren’t quite as sturdy. The locking mechanism has a cheap feel to it that suggests it may break easily.
It’s also a little less powerful than the DeWalt. For the money, you can get something that has a little more versatility.
BLACK+DECKER BDEG400 Angle Grinder – Best Value
BLACK+DECKER is always good for a solid deal. That’s certainly true in the case of our best for the money pick. The BLACK+DECKER Angle Grinder Tool is not as powerful as many of the other options on our list, but what it lacks in force, it makes up for in value and durability.
The handguard can be locked into three different positions for optimal protection. The handy metal protection case will make the tool easy to transport and store.
It has some natural limitations. Because the power levels are so modest, the motor might break down and stop working if you really put it to the test. It’s great for small jobs, but buyers who need a heavy-duty tool should keep looking.
Makita 9557PBX1 4-1/2″ Angle Grinder
The Makita 9557PBX1 is a moderately priced grinder with an extra-large wheel that will be perfect for high-volume work. We are particularly partial to the design concept, which features a specialty seal that prevents dust from ever reaching the electrical components. Check out Austgens METAL SPINNING
It’s also user-friendly. The controls are very simple, and it even includes a lock-on switch that allows you to maintain continuous operation without worrying about working the buttons.
The only real downside about this grinder is that it’s fairly heavy. The weight of the tool makes it hard to use comfortably for extended periods of time. Still, for occasional use, it’s a great grinder available at a reasonable price.
Makita 9564CV Angle Grinder
When it comes to versatility in usability and efficiency, not many angle grinders compare to the Makita 9564CV. The unique Makita 9564CV comes with variable speed in the range of 2800-10500 RPM, which allows you to switch between different disc speeds depending on your task. It, however, doesn’t have a paddle switch to accompany its tool-less adjustment feature.
This powerful and highly versatile grinder is like no other. It is appropriate for metal workshops that perform light polishing as well as hard metal fabrication. The presence of labyrinth seals in the Makita helps prevent dust and tiny metal particles from clogging up the discs. The variable speed control makes the Makita 9564CV Angle Grinder a perfect option if you perform different applications in your metalwork shop.
Metabo WEV15-125 Angle Grinder
The Metabo WEV15-125 Angle Grinder boasts of variable speed in the range of 2800-9600, making it appropriate for various uses in the metalwork shop. It also boasts of a tool-less guard adjustment feature on top of its fairly light-weight of 5.5 pounds.
The Metabo WEV15-125 Angle Grinder is a versatile tool due to its variable speed, which allows for both low and high-speed applications, making it appropriate for a busy metalwork shop. Metabo is a well-established German brand known for its durable products. Another impressive feature of the Metabo WEV15-125 Angle Grinder is its increased overload capacity that protects the device from overheating during use. The electronic soft start allows for easy start-up.
Metabo WP9-115 8.5 Amp Angle Grinder
The Metabo WP9-115 is a quick, compact grinder that’s able to produce 10,500 rotations per minute. The speed, as well as the extreme torque generated by the wheel, meaning you can do quick work out of most common tasks.
Metabo even prioritizes speed when it comes to maintenance. The fast, tool-free wheel change allows you to adjust the grinder with the touch of a button.
This grinder can be fairly uncomfortable to use. The power button is difficult to hold down. This may be a safety feature to prevent accidental activation. However, it does make the tool exhausting, and even painful, to use for long periods of time.
Not many angle grinders can compare to the efficiency of Metabo WP9-115, which boasts of a fast and highly simplistic disc change system. With this German-made tool, you can switch between discs with the press of a button. Impressively, the Metabo WP9-115 comes with a ‘dead man function’ feature that makes the grinder shut down once you remove your hands.
The Metabo WP9-115 is among the safest products in the market due to its automatic safety clutch that prevents kickback. The presence of a Metabo Longlife motor provides you with more power during use and allows the grinder to cool and run smoothly. This Germany-made beast is appropriate for first-time users and experienced metal fabricators alike.
Bosch 18V Angle-Grinder
The compact Bosch 18V Angle Grinder is made for people who need to get a lot of use out of their tool. It’s called an “all day” grinder because its electrical components are specifically designed for long-term use. They also have warranty protection, so they should last a long time.
It’s even made to be comfortable. The handle is optimized to reduce vibration, and it is also very lightweight, making it easy to use for long periods.
Because this is a high-end tool, you will pay a lot for it. Some users have also reported experiencing problems with the handguard being difficult to adjust.
Hitachi G12SR4 Angle Grinder
If you are a beginner looking to learn the ropes of using angle grinders, then you should consider the Hitachi G12SR4. The tools are conveniently light-weight. They deliver 10,000RPM, which, although it is not as fast as other options around, is still convenient enough to get the job done.
The Hitachi G12SR4 is pocket-friendly as it does not cost as much as its counterparts with superior RPMs and power output. The product comes with a slide-switch that is left mounted, which helps out in switching the grinder off to enhance safety. Its lightweight nature makes it appropriate for use, especially for first-timers who are not used to handling such devices.
PORTER-CABLE 20V Angle Grinder
One of the most impressive aspects of the Porter-Cable 20V MAX is the housing. The steel-cased tool is durable enough to stand up to job site wear and tear.
This grinder has an ergonomic handle, an adjustable handguard, and a tool-free wheel change that will make it easy to maintain. Budget buyers will also appreciate the affordable price.
Unfortunately, it’s just somewhat lacking when it comes to power. The 20v motor doesn’t have enough juice to work with harder woods or tough materials. The steel housing also makes it very heavy, which will be a drag for long-term use.
Avid Power 7.5 Amp Angle Grinder
The Avid Power 7.5 Amp Angle Grinder is an affordable grinder that will be great for buyers who are looking for a tool they can use on small tasks. The slim lightweight design will be comfortable to use, and it also includes a covering that protects against sparks and splinters.
The tool is also extremely quick. The 7.5 amps of power can generate an incredible 11,000 rotations per minute.

However, there seem to be some fundamental design flaws that make it difficult to use for extended periods. When the motor becomes overstressed due to excessive use, it gets extremely hot to the point that it can be difficult to hold. The motor can even get so hot that the tool will temporarily stop working.
For very small jobs, this Avid Power grinder will do fine. For more intense work, you’ll want a better tool.
SKIL 9295-01 Angle Grinders
The Skil 9295-01 is an affordable light-duty grinder that will be a good fit for users who don’t have a ton of experience.
It generates 11,000 rotations per minute, but it won’t be able to get much done on tougher, harder workpieces. It’s also very heavy, which makes it difficult to use for long periods. The partially metal housing makes it fairly durable, but it does come at a price.
It’s certainly a good tool for people who don’t use grinders often, but there are similarly priced options that perform a little better.
VonHaus Cordless 4 1/2” Angle Grinder Set
The VonHaus 20V MAX has a lightweight design and an impressive top speed of 11,000 rotations per minute. Unfortunately, though, it just doesn’t get very many other things right.
It’s among the pricier grinders on our list, but your money won’t buy you very much. It’s not very powerful, it gets hot extremely quickly, and many people report that theirs broke down within the first few weeks of use.
There is certainly the possibility that you might have a good experience with this tool, but it doesn’t compare very well to the other options on our list.
What should a buyer consider in buying an angle grinder?
Below you will find some buying considerations that will help you choose the perfect angle grinder for all your future projects.
The disc (AKA head or wheel) comes in a range of sizes. Pick the size that best suits your needs (ex: bigger discs may be more powerful but work poorly on more precise projects).
The disc or wheel of the grinder is indicative both of the power of the device and its overall capacity. Larger discs generally signify a more powerful tool.
Smaller discs are usually more optimal for focus jobs, or tasks that require lots of precision. When selecting for size, it’s important to closely consider the type of work you’ll eventually be using this grinder for.
Will you be taking on lots of tight angles and smaller spaces? If so, you’ll almost certainly be better served by a more compact angle grinder. If you have high-volume work, a large disc will help you produce a smooth finish in much less time.
There is lots of variation in disc size, so this is a factor to be mindful of. You can usually find discs between four to nine inches in size.
Most angle grinders are battery-powered. However, you may also find corded or even compressed air-powered options. Pay attention to the power source before finalizing a purchase.
Cordless units are prized because they have easier access to tight spots. However, they’re also limited by how much juice is in the battery. If you allow a battery to die, you may need to pause your work session for several hours while you wait for it to recharge.
Corded tools can run forever as long as you remain near a power source. Of course, they’re limited both by the cord itself, which can restrict your range of motion and by your ability to find a power outlet.
Neither option is necessarily better than the other. It’s simply a matter of deciding how and where you will be using your grinder most often.
Angle grinders can be air-powered or electric (corded and cordless), so consider how each power source might affect the unit’s performance and choose which works best with your habits.
The grinder’s speed is also an important factor in how it ultimately performs. The average grinder may range in speed between 5000-10,000 revolutions per minute. Faster speeds can rapidly produce the desired results in the hands of an experienced craftsperson.
However, there is a catch. If you are not well-versed with grinders, you may wind up damaging the workpiece with an excessively quick tool.
Angle grinders with variable speed settings are the answer to this problem. A variable speed grinder will allow you to select between several different speed ranges, to optimize the tool for the job at hand, and your own skill level.
If you do not have access to this feature, invest in something with a speed range, you’re sure you can handle.
The faster the speed, the more effective the tool will be. Manufacturers will list a “no-load” speed of anywhere from about 5,000 to 11,000 RPM. Large 7″ to 9″ angle grinders will operate at a lower RPM than the more common 4.5″ to 5″ grinders.
Wattage is indicative of the grinder’s power level. Generally speaking, higher-powered tools will also be faster, but this isn’t necessarily the case. Check out Huntsman W20 490P Welding Helmet Review
A higher wattage does mean that the motor should be able to stand up well against heavy use, excessive friction, and other forms of situational stress that well-used power tools incur on the job.
On corded electric models, the higher the amperage, the more powerful the grinder. Unfortunately, you have also to consider whether the load will trip your breaker. For cordless models, the battery voltage is a good general indicator of power, and the amp-hour (Ah) rating (aka charge capacity) is what determines how long the tool will run before the battery is drained. That said, technology varies so you could actually have an 18v angle grinder that’s more powerful than a 20v from a different brand.
Even if you want a tool that can reach speeds of 10,000 rotations per minute, you probably don’t want that speed level to kick in right away. A slow start mode is a handy safety feature that allows you to ease into the power of your grinder.
A tool is ergonomic when it has been specially made to fit the human hand. Weird, right? You’d think that every tool would be made for the human hand, but sadly, no. They needed a special word for it.
Ergonomic tools will usually be more comfortable to use. More importantly, though, they also make it less likely that you will incur long-term stress injuries such as inflammation or carpal tunnel syndrome as you use your tools.
The ergonomic movement is strong in the world of power tools. Most major manufacturers proudly promote that their tools are ergonomic. Still, it’s not something you can take for granted. If comfort is important to you, make sure the tool you’re considering is ergonomic before finalizing your buying decision.
Every tool comes into contact with lots of dust, but this is perhaps particularly true of the grinder. Not only do grinders kick up lots of dust, but, by their design concept, they also often wind up covered in it. If you’re unlucky, that dust can find its way into the inner workings of the tool and destroy the motor.
That’s why some grinders have special dust protection design elements. This might mean a special seal or even a unique design pattern that naturally funnels dust away from the device’s sensitive electrical inner workings.
Some grinders have special guards to protect your hands from splinters and sparks. It’s not a necessary feature, but it can be handy to have. You can even find adjustable handguards that can be altered to suit the needs of each unique job you’re working on.
You can get angle grinders for a wide range of prices. The nice thing is that, at least as far as power tools go, this is a relatively inexpensive one. Because the price of a decent grinder is generally fairly modest, even budget buyers are in a position where they can get something really solid.
Simply put, the more accessories your grinder is compatible with, the more versatility it’ll have. Some grinders are sold as kits with different wheels and discs, while others are sold as “tool only” where you have to supply the battery, charger, and any discs or wheels.
So that concludes our list for the best angle grinders, and we hope we have helped you to find the correct one for your needs.
Many good grinders didn’t make it into this list because we only chose the ones with the best features and highest reliability factors that have passed the test of time.
