Which angle grinder is best?

Below are reviews of the top available models of angle grinders. Our top picks for best angle grinders excel in areas we’ve found to be crucial to their overall performance. Some examples include strength, security, accuracy, longevity, and adaptability.

The value of angle grinders, in what ways? Angle grinders, in case you didn’t know, are one of the most essential welding equipment that can’t be found in any respectable metalworking workshop. They are portable tools that may be used to cut or sculpt metal, grind grooves, polish welds, and eliminate rust. Top Metal fabrication company Melbourne

Angle grinders make short work of cleaning off rough spots before TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas) welding, saving you time and effort.

However, as you may well know, it is not easy to choose the perfect one, particularly for first-time purchasers. Whether you want a corded or cordless grinder, the RPM, the disc size, the speed type, the switch, and other aspects will all need to be taken into account. Do not fret, though, because we have provided for your every need!

In this buyer’s guide, we’ll go over some of the best products available and the features you should keep an eye out for when selecting one for your metalworking needs.

Best Angle Grinder

Metabo WP9-115 8.5 Amp Angle Grinder

With a maximum speed of 10,500 RPM, the Metabo WP9-115 is a powerful, but portable, small grinder. The speed and the great torque created by the wheel allow you to make short work of most routine jobs.

Keeping up with the Metabo database is another area where speed is a top priority. Changing the grinder’s wheels is a simple push of a button’s worth of work, and it doesn’t need any tools.

Utilizing this grinder might cause some discomfort. Holding down the power button is a chore. It’s possible that this is a safeguard meant to prevent inadvertent use. However, this makes the instrument difficult to use for extended periods of time due to fatigue and perhaps discomfort.

The Metabo WP9-115 stands out among angle grinders because to its quick and easy disc changing mechanism. This handy gadget was manufactured in Germany and has a disc-switching button. The grinder will automatically turn off when you take your hands off of it, a feature called the “dead man function” that comes standard on the impressive Metabo WP9-115.

Automatic safety clutch that eliminates kickback makes the Metabo WP9-115 one of the safest devices available. A Metabo Longlife motor is included into the grinder to increase its power, keep it running smoothly, and extend its lifespan. This behemoth, built in Germany, is great for both novice and seasoned metal fabricators.

Bosch 18V Angle-Grinder

With its lightweight design and powerful motor, the Bosch 18V Angle Grinder is ideal for professionals who need to complete several projects. Because its motor and other electrical parts are built for continuous operation, we refer to it as a “all day” grinder. They’re covered by a guarantee, so you can be certain that they’ll endure a long time.

Furthermore, it is designed to be relaxing. It’s simple to use for extended periods of time because to the lightweight design and low vibration handle.

It’s going to cost you a pretty penny, but that’s to be expected given that this is a high-end instrument. A few of customers have also complained that adjusting the handguard is a hassle for them.

Hitachi G12SR4 Angle Grinder

The Hitachi G12SR4 is a great angle grinder to start with if you’re just getting started. The lightweight nature of the equipment is a major plus. Although its 10,000RPM is slower than competing choices, it is still practical for most applications.

The Hitachi G12SR4 is less expensive than others with similar RPMs and power output, making it an attractive option for those on a budget. There is a left-mounted slide-switch on the device that may be used to turn off the grinder, making it less dangerous to use. Because of how light it is, it’s a good option for those who are using these kinds of tools for the first time.

PORTER-CABLE 20V Angle Grinder

The sturdy construction of the Porter-Cable 20V MAX’s case is one of its most notable features. The tool’s steel casing ensures it will last under rough treatment on the work site.

The tool-free wheel replacement and ergonomic grip on this grinder make it simple to keep in working order. The low cost will appeal to those on a tighter budget.

Sadly, it lacks considerable power and is hence useless. The 20v motor is underpowered for tougher woods and materials. As an added downside, the steel casing makes it quite hefty.

DEWALT DWE402 4.5″ Angle Grinder – Best Overall

The DeWalt DWE402 11-amp grinder is an amazingly powerful tool that will make short work of both high-volume and precise tasks.

It is designed to be lightweight and small enough to fit into tight spaces, and it has a dust ejection system that protects the motor from wear and tear.

The issue of security should not be overlooked. The handguard may be rotated around the whole tool to shield you from any flying sparks or bits of debris. A protective case is included for hassle-free travel.

As is typical with DeWalt, this is an expensive tool when compared to other angle grinders. Additionally, the extreme levels of power may be overwhelming for novices. Not being familiar with grinders increases the risk of damaging the workpiece by over-grinding.

Power tools known as angle grinders may be used for a wide variety of tasks, including cutting and polishing using abrasive discs (also called a cutting wheel). Discs may be switched out using either a wrench or a “quick change” assembly, depending on the device.

The disc’s kind limits the tasks that may be performed. Polishing with a wire brush wheel and grinding away superfluous metal with a disc are just two examples of the many uses for abrasive wheels. Although discs come in a wide range of diameters, 4-1/2″ is the most frequent.

Angle grinders may be powered by either a wire or batteries. Grinders that use compressed air are also widely available.

Noise, sparks, and broken discs are all side effects of using a grinder. Because of this, it’s important to constantly wear protective gear, such as earplugs, gloves, safety goggles, and a face shield. Both a clamp and a vice should be used to keep the workpiece in place while it is being worked on.

Milwaukee 2780-20 Angle Grinder

Compared to the DeWalt, the Milwaukee 2780-20 is quite similar. It’s robust, with a movable handguard, dust-proof construction, and a hard-plated carrying box.

The tool’s cost is our primary concern. It costs more than the DeWalt but falls short in one crucial area of performance. Some of the parts aren’t as strong as others. The locking mechanism seems cheap, like it may break quickly.

Compared to the DeWalt, it has a little less power. You can purchase something with a little more flexibility for the same price.

BLACK+DECKER BDEG400 Angle Grinder – Best Value

You can always count on a decent bargain from BLACK+DECKER. Indeed, such is the case with our top option that also happens to be the greatest value. While the BLACK+DECKER Angle Grinder Tool may not be as potent as some of the other alternatives we’ve provided, it more than makes up for its lack of power with its reasonable price and long lifespan.

The handguard has three locking configurations for varying levels of security. The tool’s protective metal case will come in useful both during shipping and while stowing it away.

Inherent constraints prevent it from becoming perfect. Due to the little available power, the motor might fail if subjected to extreme conditions. Good for light work, but not for those who require something more robust.

Makita 9557PBX1 4-1/2″ Angle Grinder

The Makita 9557PBX1 is a grinder with a big wheel and a reasonable price, making it ideal for production settings. The design idea is one of our favourites because of the specific seal that keeps dust out of the electronics. Check out Austgens METAL SPINNING

Furthermore, it’s simple to operate. The controls are intuitive, and a lock-on switch ensures constant power without the need for constant finger-flicking.

The grinder’s bulkiness is its one major drawback. The heavy nature of the instrument makes it uncomfortable to use for long periods of time. Still, it’s a high-quality grinder at a low price, perfect for occasional usage.

Makita 9564CV Angle Grinder

It’s hard to find an angle grinder that can compete with the Makita 9564CV in terms of use, efficiency, and overall utility. The Makita 9564CV is one-of-a-kind because it has a variable speed range of 2800-10500 RPM, allowing you to adjust the disc speed to suit the application at hand. The tool-free adjustment option is absent, though, as is a paddle switch.

When it comes to grinders, nothing compares to the power and adaptability of this one. It’s great for metal businesses that do both delicate polishing and robust metalwork. Makita’s discs are protected from dust and small metal particles by a system of labyrinth seals. The Makita 9564CV Angle Grinder is an excellent choice for use in a metalworking shop because to its variable speed control.

Metabo WEV15-125 Angle Grinder

The Metabo WEV15-125 Angle Grinder is versatile because to its variable speed range of 2800-9600 RPM, which is useful in the metalworking industry. In addition to its relatively low weight (5.5 pounds), it also has a guard that can be adjusted without the need of tools.

The Metabo WEV15-125 Angle Grinder’s variable speed makes it useful in every metalworking environment, from the most mundane to the most demanding tasks. A trusted German manufacturer, Metabo is recognised for producing high-quality tools that last. The improved overload capacity that safeguards the Metabo WEV15-125 Angle Grinder from overheating is another noteworthy feature. Starting is simple because to the automatic soft start.

Avid Power 7.5 Amp Angle Grinder

Inexpensive and effective, the Avid Power 7.5 Amp Angle Grinder is an excellent option for anybody in need of a small-duty grinder. A small, lightweight design makes this tool easy to hold and operate, and a protective covering keeps users safe from flying sparks and splinters.

The speed of the tool is another plus. Using just 7.5 amps, 11,000 RPM may be produced.

However, it seems to have several serious design problems that make it uncomfortable to use for long periods of time. When the engine is overworked, the temperature rises rapidly, making it uncomfortable to handle. Because of the motor’s heat, the tool may potentially malfunction for a while.

This Avid Power grinder will perform just fine for little tasks. You’ll need a more powerful instrument for the demanding labour ahead.

SKIL 9295-01 Angle Grinders

The Skil 9295-01 is a low-priced light-duty grinder that will work well for inexperienced users.

It can produce 11,000 revolutions per minute, however its effectiveness is limited when working with harder materials. It’s also somewhat cumbersome, making prolonged usage uncomfortable. It’s quite long-lasting thanks to its metal chassis, but that strength comes at a cost.

It’s a decent alternative for those who don’t need a grinder very frequently, but you can get better ones at a same price.

VonHaus Cordless 4 1/2″ Angle Grinder Set

With its compact build and high maximum speed of 11,000 RPM, the VonHaus 20V MAX is a powerhouse in its class. However, it falls short in many other respects.

It’s one of the most expensive grinders we reviewed, but you won’t get much for the cost. It’s not very effective, it overheats easily, and several users have complained that it stopped working after just a few weeks.

Even though you could like using this tool, it doesn’t stack up to the others we’ve recommended.

What Should a Buyer Consider in Buying an Angle Grinder?

Below, you’ll discover some things to think about while shopping for an angle grinder that should help you choose the best one for your needs.

Disc Size

There is a wide variety of available sizes for the disc, also known as the head or wheel. Decide on the optimal dimensions for your requirements (ex: bigger discs may be more powerful but work poorly on more precise projects).

The disc, or wheel, of the grinder is representative of the device’s power and total capacity. A more powerful instrument is often represented by a larger disc.

Focus jobs, or those that need a high degree of accuracy, often benefit more from the use of smaller discs. The sort of task you’ll be utilising the grinder for down the road should factor heavily into your decision on the ideal grinder size.

Do you plan on dealing with a lot of odd angles and cramped quarters? If that’s the case, you’ll do much better with a smaller angle grinder. A big disc will help you get a nice, even finish on a lot of work very quickly.

It’s important to keep in mind that disc sizes might vary widely. Discs typically range in diameter from four to nine inches.

Power Source

As a rule, cordless angle grinders need batteries. Nonetheless, you might also purchase compressed air-powered or corded models. Before making a final decision, think about how the device will be powered.

Cordless appliances are more desirable than their wired counterparts since they can reach farther into corners. However, they are restricted by the power available from the battery. If you let a battery die, you may have to stop what you’re doing for a few hours while it charges.

Corded tools may be used indefinitely so long as they are plugged into an outlet. Obviously, they are restricted by the cord, which might limit your mobility, and by the accessibility of an electrical outlet.

Neither choice automatically outperforms the other. What matters most is how and where you plan to use your grinder.

Angle grinders may be driven by either air or electricity (both corded and cordless versions exist), so it’s important to think about how each option can impact the tool’s performance before making a purchase.

Speed

The effectiveness of a grinder depends not only on how powerful it is, but also on how fast it can grind. It’s possible that the RPM of the typical grinder is somewhere between 5,000 and 10,000. In the hands of a skilled artisan, higher speeds may quickly provide the appropriate results.

The catch is, however, that there is a catch. Those who aren’t familiar with using grinders might easily ruin a project by using the machine too quickly.

The solution to this issue is the use of angle grinders with adjustable speeds. With a variable-speed grinder, you can adjust the speed to suit the task at hand and your own degree of expertise.

In the absence of this capability, you should save up for something whose top speed is well within your capabilities.

The more quickly a tool can operate, the more useful it will be. The “no-load” speed given by manufacturers may range from around 5,000 to 11,000 RPM. The RPM of larger 7′′ to 9′′ angle grinders is lower than that of more conventional 4.5′′ to 5′′ grinders.

Wattage

The number of watts indicates the grinder’s efficiency. In most cases, more powerful instruments will also have greater speed, although this is not always the case. Check out Huntsman W20 490P Welding Helmet Review

Higher wattage indicates that the motor should be able to withstand the strain that comes from regular usage, including the increased friction that occurs while working with power tools.

In general, the more powerful a corded electric grinder is, the greater the amperage rating. Regrettably, you must also think about whether or not the load may cause your breaker to trip. The voltage of a cordless model’s battery is a rough estimate of its power, but the amp-hour (Ah) rating (also known as charge capacity) is what defines how long the tool will operate before the battery dies. However, as technology evolves, you can find an 18-volt angle grinder that outperforms a 20-volt one from a different manufacturer.

Slow Start

You generally don’t want a tool to start spinning at full speed straight immediately, even if it can reach 10,000 RPM. To gradually get used to the grinder’s power, a slow start option is a helpful safety feature.

Ergonomics

When a device is tailored to the human hand, we say that it is ergonomic. Odd, huh? One may assume that all tools would be created with the human hand in mind, but alas, this is not the case. They had to come up with their own term for it.

Tools that have been optimised for the user’s anatomy are called ergonomic. In addition to reducing the risk of short-term ailments including inflammation and carpal tunnel syndrome, they significantly improve tool performance.

In the realm of power tools, the ergonomic trend is robust. The majority of well-known producers boast that their products are ergonomic. Nonetheless, it is not something to take for granted. Whether convenience and ease of use are high on your list of priorities, then you should check to see if the item you’re thinking about purchasing is ergonomic.

Dust Sealed

The grinder, more than most other tools, is exposed to a great deal of dust. Not only do grinders generate a great deal of dust, but the very nature of their construction means that they often get caked in the stuff themselves. Dust might potentially enter the tool’s internals and damage the motor if you’re not careful.

Because of this, several types of grinders are equipped with features specifically meant to prevent the spread of dust. This might be accomplished with a dust-proof seal or with a specially-designed pattern that guides airflow away from the device’s delicate electronic components.

Hand Guard

Guards are available for certain grinders, preventing injury to your hands from flying debris and sparks. While not absolutely necessary, it is a nice to have. Even better, you may discover handguards that can be adjusted to fit your specific demands on every given project.

Price

The cost of angle grinders may vary widely. The plus is that it’s cheap, at least in comparison to other power tools. A good grinder may be had at a relatively low cost, making them accessible to shoppers of all financial means.

Accessories 

It’s as simple as this: the wider the range of attachments available for your grinder, the more uses you’ll find for it. Some grinders are offered in “kit” form, with a variety of wheels and discs included in the package, while others are supplied as “tool alone,” requiring the buyer to provide their own power source, charging equipment, and grinding accessories.

We hope that our list of the top angle grinders was helpful in narrowing down your options to the one that best suits your requirements.

Unfortunately, many worthy grinders were left off this list in favour of those that have stood the test of time in terms of quality and durability.

Conclusion

Angle grinders are indispensable pieces of welding gear that can be used for a wide variety of tasks, including cutting and sculpting metal, grinding grooves, polishing welds, and removing rust. They’re fantastic at things like durability, precision, flexibility, and sturdiness. With a maximum RPM of 10,500, the Metabo WP9-115 8.5 Amp Angle Grinder is a speedy and compact small grinder. It has a simple mechanism for swapping out discs, and the disc-switching button deactivates itself when the user’s hands are removed. The Metabo WP9-115 is a top-tier piece of equipment thanks to its Metabo Longlife motor and automatic safety clutch, which together boost output, guarantee trouble-free operation, and lengthen the tool’s service life.

If you’re a professional with multiple projects on the go, the Bosch 18V Angle-Grinder is a great choice, while the Hitachi G12SR4 is a great angle grinder for beginners. The Porter-Cable 20V MAX is a great option for those on a budget thanks to its lightweight design and comfortable grip, but its underpowered 20v motor prevents it from handling tougher woods and materials. The Black+DECKER BDEG400 Angle Grinder is a high-priced tool made to be portable and compact for use in confined spaces. Dust is ejected away from the motor to prevent damage, and a carrying case is included for convenience. Noise, sparks, and cracked discs are all unavoidable byproducts of the device’s dependence on either an electrical connection or batteries for power.

Use a vice and clamp to secure the workpiece in place and protect your ears, hands, and eyes from flying debris. The Black+DECKER Angle Grinder Tool is an affordable and durable grinder. The speed can be adjusted from 2800 to 10500 RPM, and a lock-on switch keeps the motor running without the user having to hold down a button. It’s perfect for those who don’t need anything too sturdy, but it won’t stand up to heavy labour. The Makita 9557PBX1 4-1/2″ Angle Grinder features a sizable wheel at a fair price, while the Makita 9564CV Angle Grinder, with its variable speed control, is a great option for use in a metalworking shop.

The Metabo WEV15-125 Angle Grinder can be used for a variety of purposes thanks to its tool-free guard adjustment and variable speed (from 2800 to 9600 RPM). Although it is cheap and does the job, it is not comfortable to use for extended periods of time due to several design flaws. Skil 9295-01 Light-duty grinders like angle grinders are inexpensive and convenient, but they have their limits when working with tougher materials. The VonHaus Cordless 4.5-Inch Angle Grinder Set dominates its competition.

Consider disc size, power source, speed, and location when searching for an angle grinder. Power and capacity are indicated by the size of the disc, while the type of use and the location of the grinder determine the available power and the grinder’s speed. Discs are typically between four and nine inches in diameter, and corded power tools can be used indefinitely so long as they are plugged into an outlet. Power alone is not enough to determine a grinder’s usefulness; the speed at which it can grind also matters. You can solve this problem by investing in a variable-speed angle grinder, but you should only use it at speeds that are well within your capabilities.

Higher wattage means the motor should be able to handle the strain of regular use, so it’s a good indicator of the grinder’s efficiency. The amp-hour (Ah) rating (also known as charge capacity) of a cordless model’s battery is what defines how long the tool will operate before the battery dies, while the voltage is just an estimate of its power. Ergonomic tools are designed with the user in mind, making them more comfortable to use and less likely to cause any temporary injuries. Even though ergonomics are all the rage in the world of power tools, you should still make sure that the tool you’re planning to buy fits the bill.

Grinder dust containment features are standard on dust sealed models. There is a wide range in how much an angle grinder will set you back, but in general, these power tools are very affordable. Some grinders come with adjustable handguards that shield the user’s hands from debris and sparks while grinding. Sometimes extras like grinding wheels and discs are thrown in with the purchase, but in other cases the customer must supply their own power supply, charging equipment, and grinding accessories. Regrettably, this list only includes grinders that have proven their quality and durability over time, leaving out many deserving competitors.

FAQs About Metal

Which Grinder Size Is Best?

A smaller 115mm angle grinder means a more versatile power tool. With a smaller cutting disc you get a greater level of precision, so if you’re wanting to be able to trim tiles to shape, sharpen blades, or cut and grind more intricate stone and metalwork projects, we’d suggest a 115mm grinder.

How Long Does an Angle Grinder Last?

It is not uncommon for very cheap angle grinders to only last for ten or even just five hours. Yes, people, you read that right, five hours of grinding. There is no straightforward answer here. However, if you buy a relatively high-quality model, you can expect it to last for anywhere from seven to 15 years.

Why Is It Called an Angle Grinder?

The motor drives a geared head at a right-angle on which is mounted an abrasive disc or a thinner cut-off disc, either of which can be replaced when worn.

How Thick Can an Angle Grinder Cut?

The most common grinder disc size is with a diameter of 12 cm. It can be used for small jobs as cutting wood or metal with a maximum thickness of 2-3 cm. It’s not recommended to use it for cutting stones and concrete.

Do Angle Grinders Cut Metal?

You can use angle grinder to cut metal and all types of it, including bolts, angle iron, rebar, and even sheet metal, when it’s equipped with an abrasive metal-cutting disc. However, as you use the discs, they wear down fast, cut slowly, and reduce in diameter.
