Angle grinders are versatile power tools that can handle a variety of projects, such as cutting iron pipe to replace a faulty valve, carving wood to craft furniture, cutting tile for a backsplash, and removing grout from between tiles.

Interchangeable rotating discs—some made for cutting and others with an abrasive edge for grinding—can be swapped out based on the application. For safety, a guard sits between the disc and the handle to protect the operator.

What to Consider When Choosing the Best Angle Grinder

There are a few things to understand before clicking “add to cart” on just any old angle grinder. The best angle grinders may have unique features, different power sources, and some might simply be better suited to particulars. The following points are worth considering when shopping for a good quality grinder.

Disc Size

Angle grinders come in sizes, denoted by a number that refers to the maximum diameter of the grinding wheel or disc it will handle. For most DIY projects, a 4-, 4.5-, or 5-inch disc will suffice. In fact, these compact sizes and weights are ideal for DIYers, as larger discs can become unwieldy or tedious to work with.

Larger discs (up to 9 inches) are more commonly used in industrial situations by professionals cutting through thick pieces of material. As the disc gets larger, the grinder itself must be larger to handle the cutting strength. This translates to a heavier tool that’s likely to cause hand fatigue sooner than using a small angle grinder.

Power Source

Angle grinders are available as corded models (which plug into an electrical outlet) and cordless (which use a battery).

  • Corded grinders typically generate more power at a consistent level due to the direct connection to the outlet. But corded models restrict the user to a physical location, limiting range without an extension cord. The cords can also be a tripping hazard and, therefore, a nuisance while working on a project.
  • Typically, cordless grinders lack the sheer power of their corded counterparts. And functionality depends on battery capacity, so a dead battery could mean downtime in the middle of the project. On the plus side, cordless angle grinders offer hassle-free mobility and are better for use in tight spaces.

Speed

Angle grinder speed is measured in revolutions per minute (rpm). Speeds typically range between 5,000 and 10,000 rpm, though some very robust grinders reach up to 12,000 rpm. Keep in mind, however, that the rpm rating is under “no-load” conditions, meaning that the disc isn’t cutting or grinding anything, just spinning in the air. Once the disc is cutting or grinding, that speed will lower considerably.

Obviously, the higher the rpm, the easier and more quickly the tool can cut through the target material. But the disc also becomes hotter at higher speeds and could be vulnerable to rupture—an injury risk. Be sure to use the correct disc for the task, and note the maximum supported speed marked on the disc. For example, a disc rated at 7,500 rpm that is running faster can break under the force, sending shards of the grinder wheel flying.

Voltage/Amperage

Angle grinders measure power output potential in volts (V) and amperes (amps). Cordless angle grinders use volts to measure the power available from their battery, with most cordless models using 18-volt or 20-volt batteries and outliers ranging from 7.5 volts to 24 volts. The “magic number” in most cordless power tools is 18 volts to 20 volts, offering the best mix of affordability and functionality.

Voltage readings on corded angle grinders only indicate whether they can be used with 120-volt or 220-volt power outlets. Shoppers can assess the power output potential of corded models by checking amperage, which ranges from 5 amps to 15 amps. Larger discs will require a larger output, so for a 7- or 9-inch grinder, expect it to have a higher power output potential.

Hand Guard

The guard on an angle grinder is a crucial safety measure that covers half the disc. Its purpose is to protect the user’s hands, by preventing sparks and debris from flying toward the user, and to protect surfaces from damage when using the grinder in tight spaces.

Some angle grinders have a movable guard, and others have a fixed guard. The movable option is more popular as it allows for left-handed or right-handed use and can adjust to better protect the user from flying debris. If left untightened, however, a movable guard can fall off the unit. Fixed guards are more robust, and there’s no risk of them coming off a grinder.

Soft Start

Because angle grinders are fast, powerful tools, they can recoil a bit upon power-up. This is particularly true if the grinding wheel is large and heavy. The recoil from the motor can result in the angle grinder jumping in the user’s hands, potentially causing serious injury.

To combat recoil, soft-start technology reduces the power output to the motor at first, slowly increasing until the angle grinder is fully up to speed. This throttled control over the power output prevents an angle grinder from recoiling during start-up, increasing safety while also reducing the jolt to the user’s arms and wrists.

Tips for Buying and Using an Angle Grinder

Keep these tips in mind when choosing and using an angle grinder.

  • The most common DIY projects where an angle grinder will be of use—such as cutting tile or pipe, metalworking, or removing grout and mortar—rarely require more than a 4.5-inch grinder.
  • The ongoing vibration of an angle grinder can cause what is known as Hand-Arm Vibration Syndrome (HAVS), with symptoms including pain and cold sensations in the user’s fingers, loss of grip strength, and a loss of sensation in the fingers and hands. An angle grinder with cushioned or vibration absorbent material on the grip can protect hands from ongoing vibration.
  • Always wear personal protective equipment (PPE) including safety glasses/goggles, hearing protection, and respiratory protection when grinding.
  • Check the grinder before use to ensure the disc and guard are properly attached and tightened. Discs and guards can become loose between uses. Tighten them before connecting the power to the angle grinder.

Our Top Picks

While all that information on the best angle grinders ought to be helpful when shopping, there’s really no substitute for hands-on testing. Tom had the pleasure of personally putting all the following angle grinders through their paces during a recent metalworking project.

Each of the models reviewed passed our tests and met our standards (see “How We Tested,” below), though Tom found some models better for specific tasks than others. Note that all of the following models feature movable guards and screw-in handles.

The Makita XAG04Z is worth checking out by anyone looking for the best cordless angle grinder performance. This top-rated angle grinder features an 8,500 rpm top speed thanks to its brushless motor and the 18-volt lithium-ion battery. It can handle 4.5- and 5-inch discs.

We found the XAG04Z excellent to work with. While it doesn’t boast the highest top speed, the automatic speed adjustment enabled it to maintain speed during tough cuts and grinds. We noticed very little vibration thanks to the rubber over-molded grip and handle, and the lock-on switch proved to be a huge plus.

The only downsides I see: Assembling the two-piece handguard was a little awkward, and it would be nice if the tool came with a battery and a charger.

Product Specs

  • Model:XAG04Z
  • Disc Size: 5-inch
  • RPMs: 8,500
  • Power Source: 18-volt lithium-ion battery

Pros

  • Automatically adjusts speed and torque settings
  • Slow start keeps the tool from jumping
  • Lock-on switch
  • Very little noticeable vibration

Cons

  • No battery or charger included
  • Guard is a bit finicky

When it comes to DIY projects and budgets, not everyone can afford top-of-the-line tools every time. So those hoping to save cash and still get a quality grinder may want to give this corded model from Metabo HPT a look. It uses 4.5-inch discs, has a 6.2-amp motor, and spins at up to 10,000 rpm.

This is one of the best 4.5 inch angle grinder options for the money, and the Metabo HPT’s usefulness was somewhat of a surprise. I enjoyed how compact and lightweight it was in my hand. The location of the power switch is very convenient, especially during cutting.

The lock-on feature allowed me to kick it on and leave it on—very helpful in my project. My only complaint is that the Metabo HPT lacks the power of other corded models, and the 6.2-amp motor seemed like it could overheat during all-day use.

Product Specs

  • Model: G12SR4
  • Disc Size: 4.5-inch
  • RPMs: 10,000
  • Power Source: Corded

Pros

  • Lightweight angle grinder (only 4 pounds)
  • The most compact of all the grinders tested

Cons

  • A little lacking in power compared to other corded models
  • The 6.2-amp motor isn’t ideal for all-day use

DeWalt’s 20V Max XR Brushless Cut-Off/Grinder cordless angle grinder could be the ultimate upgrade for pros and DIYers who take their tools seriously. This cordless model utilizes the brand’s 20-volt Max XR lineup, and its brushless motor spins 4.5-inch discs up to 9,000 rpm.

My experience with this DeWalt model was just as I expected: great portability and truly outstanding power. It made short work of cutting and grinding, without a cord to get in the way. The grip and handle both feature thick rubber, keeping vibration and fatigue to a minimum.

The safety features are certainly a plus: The electronic brake stopped the disc within 2 seconds (other models can take up to 10 seconds), and simply knowing that there is a kickback brake instilled confidence.

Product Specs

  • Model:DCG413B & DCB230C
  • Disc Size: 4.5-inch
  • RPMs: 9,000
  • Power Source: 20-volt lithium-ion battery

This Porter-Cable product is one of the top corded angle grinder options for dependable power. This model features a heavy-duty 7.5-amp motor that spins a 4.5-inch disc at speeds up to 10,000 rpm, providing plenty of speed and power for workshop use.

The Porter-Cable grinder felt truly in its element on my metalworking project, handling cuts and grinds nicely. While it doesn’t have the most power compared to others on our list, it’s pretty close. It’s also one of the only grinders to feature a traditional trigger switch, which I felt was easy to use and more intuitive than most. I also really liked the top-mount position for the handle attachment, as it can make cutting much more manageable.

Product Specs

  • Model:PC750AG
  • Disc Size: 4.5-inch
  • RPMs: 10,000
  • Power Source: Corded

Pros

  • Top-mounted handle position

If you’re searching for the best angle grinder for wood carving, sanding, grout removal, and other light-duty projects, Black & Decker’s Angle Grinder Tool might be a wise choice. This affordable model features a 6-amp motor that produces up to 10,000 rpm of speed, and it’s compatible with 4.5-inch grinding and cutting wheels.

Black & Decker markets this model at light-duty, DIY-type users, and that’s where it excels. This very affordable model is easy to use, thanks in part to its lock-on trigger. The three-position handle mounting system works for plenty of scenarios, such as cutting and grinding at unusual angles. Just don’t expect the Black & Decker to handle heavy-duty jobs like large metalworking projects for any length of time, as it only has a 6-amp motor.

Product Specs

  • Model:BDEG400
  • Disc Size: 4.5-inch
  • RPMs: 10,000
  • Power Source: Corded

Pros

  • Plenty of capability for the price
  • Three-position handle, including top-mount
  • Trigger locks into position

Cons

  • 6-amp motor is only suitable for light-duty work

Heavy-duty projects like production welding and cutting require a grinder that can keep up, and DeWalt’s DWE402 can handle the job. This burly machine features an 11-amp motor and spins 4.5-inch grinding and cutting wheels at speeds up to 11,000 rpm.

I found the DWE402 to be the ideal grinder for my work, though not everyone will need its power and high-speed capabilities. It cut through angle iron faster than any other grinder, and it made short work of my large, lumpy, amateur-grade welds (though it’s definitely a pro-grade tool, and the speed-boosting button on the handle base helped a lot).

While this is one of the best variable speed angle grinders, neither the DWE402’s vibration control nor its grip got much attention on the drawing board.

Product Specs

  • Model:DWE402

  • Very fast and powerful
  • High amperage motor for heavy-duty work

Cons

  • Not much vibration control

Our Verdict

With portability and power in mind, the Makita XAG04Z is a great choice for almost any home workshop, though pros may also appreciate this model. And for those who need the best angle grinder for cutting metal and other heavy-duty weld materials, the DeWalt DWE402 has the power and speed to match.

How We Tested the Best Angle Grinders

Sometimes, I have the best job in the world. I’ve had a project on my plate for months now (building a welding cart), and it just so happened to be the ideal project to test these top angle grinders. I used the same set of cutting and grinding wheels for each model to make apples-to-apples comparisons.

I used each grinder to cut through angle iron, switching grinders between each cut until I felt comfortable with the strengths and weaknesses of each model. I recorded myself cutting all the pieces for the welding cart in order to determine how long each cut took and how easy it was to use. After cutting all the pieces, I welded the cart together (rather heavy-handedly, I admit, as it’s been a few years since I last welded).

With those big, burly welds to address, I used each grinder to knock them down to flush. Again, I noted ease of use and handling. In the end, I had all I needed for these honest angle grinder reviews—as well as a cart for my new welder.

Historically, most people would baulk at the idea of spending good money on a used or second hand tool, but today’s refurbished models are not the dubious equipment found at a neighborhood yard sale. For some time, reputable manufacturers and retailers have been offering refurbished or renewed products like angle grinders alongside new models.

The idea is that when a commercially viable fix is possible, it cuts down on waste—which is always a good thing. It may also offer buyers the opportunity to acquire products that might otherwise be outside their budget.

These should not be tools that have been beaten to death for 364 days and returned on the day the warranty expires. It’s true that often they have been tried by another buyer but will have been returned within a relatively short return window. Other times, they might be tools damaged in transit or in the warehouse.

So are refurbished angle grinders any good? In our opinion, yes. There’s every chance they could represent a real bargain. There are some interesting offers on refurbished or renewed angle grinders at Amazon and Walmart among others. However, care and common sense is needed.

  • Specify the type of angle grinder you want first. Look at new models. Then see what you can get on the refurbished market that comes close to those specifications.
  • Keep a tight rein on your budget. It’s easy to get carried away. The idea here is to save money, or get better value.
  • You should be looking for a substantial cost reduction. If the saving is only saving 10 percent or 15 percent, it might be better to buy new.
    Make sure you know exactly what is included. Cordless tools often won’t include battery or charger, for example.
  • Be sure to check warranty and return periods before you order. Don’t make assumptions, even if you bought from the retailer before.

While refurbished, reconditioned, or renewed tools are often excellent, there’s always a chance it could be a dud. Buy from a reputable source. Check the angle grinder as soon as it arrives so you can get your money back if there’s a problem.

FAQs

Even with ample background on the best angle grinders, you might have some additional questions. Here, we answer some of the most common queries about angle grinders, so check for the info you need below.

Q: What kind of tasks can I use an angle grinder for?

The most common uses for angle grinders are metal grinding and cutting, such as steel for welding or metal piping. However, they’re also useful for wood carving, refinishing, and other projects. Some farriers even use them to trim hooves.

Q: How does an angle grinder operate?

After attaching the correct disc for the job, hold the angle grinder in two hands for safety and security (the tool’s initial torque will cause it to jump). Push the trigger down or hit the power switch, and the disc will start rotating. Move the grinder until the rotating disc contacts the material you want to cut or grind.

When finished, release the trigger or switch off the power button and wait for the disc to stop rotating completely before placing it in a safe location, keeping in mind that the disc is still hot due to the friction caused during operation. Unplug the power cord or detach the battery and allow the tool to cool down.

Q: How much does an angle grinder cost?

An angle grinder can range in price from just $30 to over $200, though it’s more common for these tools to cost about $80 to $100.

Q: How do you cut metal with an angle grinder?

Use a metal cutting disc on an angle grinder to cut through lead, iron, copper, and other metals without a problem. The rotating blade slices easily through metal, but it’s important to wear safety glasses and gloves because a significant amount of sparks are produced during the grinding process.

Q: How do you cut pavers with an angle grinder?

Angle grinder equipped with masonry discs can be used to cut through paving stones without much difficulty. Measure and mark where you want to cut the paver, then position it on a workbench. Turn the grinder on and start to slowly cut into the paving stone. Once you have started the cut it will be easier to accurately finish cutting through the paver.

Q: How are the discs on an angle grinder changed?

First, unplug the grinder or remove the battery. Then remove the nut that holds the disc in place, using the factory spanner included with the angle grinder. Replace the disc and tighten the nut bolt using the factory spanner.

Q: How can I remove the disc with vise grips?

Grinder discs are secured with a specialized nut that is usually tightened or removed with an included spanner. However, if you lose the spanner the nut can still be removed with a set of vise grips. Simply tighten the vice on the grinder blade, locking it in position, then use your hand or a screwdriver to turn and remove the locking nut.

Q: How do you properly recycle an old angle grinder?

Instead of tossing your old angle grinder in the trash, take it to a local electronics recycling location. Typically, the municipality or town will have a program for recycling electronic tools and other devices, though some home improvement stores, like Home Depot, also offer tool recycling programs.

Snap-off blades include standard wedge-type blades for smaller hobby knives and heavier-duty segmented blades.. Sure, you can get a straight-up blade with no frills, but some of these nifty features make using a utility knife something much more useful.. While some people prefer “old school” utility knives that require a flat head screwdriver to separate the body into halves to change the blade, our personal favorite are the models that use a simple button to swap blades.. Most utility knives offer internal blade storage, but increasingly, knives are coming up with more convenient ways to access those blades.

While angle grinders aren’t exactly the most dangerous tool out there, you still need to exercise a lot of caution when using them.. Angle grinders are powerful tools meant to grind away materials like metal.. In this article, I want to talk about the possible dangers of using an angle grinder , as well as some safety tips that you should keep in mind that will help you avoid accidents while using the tool.. The main reasons for angle grinder accidents are abrasive disc shattering and improper use of the equipment..

So for the last few years, we’ve been in a situation where increasing numbers of (essentially armed), thieves are using compact and powerful portable angle grinders to steal whichever bike they choose, irrespective of how its been secured.. Why would most thieves need angle grinders when huge numbers of cyclists are still “securing” their bikes with cable locks that can be snipped through with a tiny pair of cable cutters?. First came the SkunkLock , a bicycle lock that doesn’t aim to prevent an angle grinder cutting through its shackle, but instead to severely punish the thief wielding the angle grinder by releasing a cloud of noxious, vomit inducing gas into their face, preventing them from actually stealing the bike.. While the SkunkLock and Altor SAF are undoubtedly fantastic innovations and will certainly protect against angle grinder theft, due to their bulk, they’re unlikely to become mainstream portable bike locks.. What we really need is a regular looking bike lock that an angle grinder is unable to cut.. Hiplok D1000: the world first portable angle grinder proof bike lock. Because Hiplok (a company that's made it’s name with bicycle locks that are easier to carry around), are about to release the world’s first truly portable, anti angle grinder bike lock, and the secret sauce is a new material called “Ferosafe”.. Cycling Weekly used a mains powered angle grinder against the lock while it was held in a vice and it took them over 20 minutes and they destroyed 5 cutting discs before they got through the lock...

The components of an angle grinder are classified into two groups: mechanical parts and electrical parts.. Disc An abrasive disc (or abrasive wheel) is a vital part of an angle grinder.. When picking a disc for your tool, you should ensure that its maximum speed (often printed on the product label) is equal to or more than the maximum rotating speed of your angle grinder.. If the disc’s safest operating speed is lower than that of the grinder, don’t use that disc as there will be shatter once the grinder works at its maximum speed.. Geared head A geared head is placed at the front of an angle grinder and consists of bevel gears that deliver the energy from the electric motor to the spindle.. When the angle grinder is working, this part will turn at a high speed to drive the grinder’s disc or attachment.. Guard Almost every angle grinder goes with a protective guard to protect you from flying metal debris or hot sparks while the tool is working.. No-Volt release switch On some latest angle grinder models, there is a No-Volt release switch to prevent the tool from accidental starts.. Brush cover On angle grinders that run on a carbon brushed motor, there is a brush cover to protect the engine from damages, dust, and debris.. Power cord The power cord is often seen on corded angle grinders and other power tools like jigsaws, electric drills, routers, etc.. Brush A brushed motor (on the angle grinder models that run on a carbon brushed motor) consists of many carbon brushes (or motor brushes).. Using a worn brush on a high-powered tool like an angle grinder can lead to reduced motor power or reduced electrical braking.. After learning the angle grinder parts name , you understand that while an angle grinder might seem a simple tool, it consists of many small mechanical and electrical components and additional features that you need to learn how to use.. Now you can quickly identify the faults of your angle grinder, repair your tool with less time and effort, or purchase replacement of the broken part with more confidence.
