Angle grinder attachments for woodworking and cutting. Wood grinder tool
Can you cut wood with an angle grinder?
If you are doing some DIY around your home but you’re lacking the tools you need, you might be wondering, can you cut wood with an angle grinder? After all, it has a tough blade that can cut through all kinds of other materials.
It is possible to use an angle grinder to cut wood, so if you don’t have a saw, this might be the next best option. It’s also a quick and easy one, but it is not considered particularly safe. You should also note that you will need the right kind of blade for this task.
Can You Cut Wood With An Angle Grinder?
You can cut wood with an angle grinder. Angle grinders utilize a sharp, spinning blade that will slice through most materials, and will certainly cut wood. However, there are a few things that you should be aware of:
- Angle grinders won’t cut through a large piece of wood, as they can only cut through fairly small areas before their blade guards will get in the way.
- Wood is flammable, and angle grinders produce a lot of heat.
- You will have limited control because it is so easy to cut through the wood. This makes it very easy to slip and hurt yourself or damage another object.
- Grinders don’t stop spinning as soon as you stop engaging them, which can lead to damage if you aren’t very careful while using them.
Is It Safe To Cut Wood With An Angle Grinder?
Cutting wood with an angle grinder isn’t very safe for a number of reasons. One is the fire risk – grinders get hot and wood is flammable. Be careful about this.
The second reason is the lack of control. Because the grinder will slice through the wood very quickly and easily, even a slight shift in your angle can lead to you veering off course and potentially cutting yourself. Using the right blade will reduce the risk of injury, but you still need to be very careful!
Pros and cons
- This wood cutting disk is specifically made for angle grinders and therefore relatively safe to use.
- It only has 3 teeth, effectively reducing the speed of the blade. This is good while angle grinders have a much higher RPM then a saw.
- If one of the three teeth breaks the grinding disc will be useless and needs to be replaced.
Tips To Avoid Mistakes
There are a few things you should make sure you aren’t doing when you cut wood with an angle grinder.
Mistake 1: Working too fast. Because angle grinders are such aggressive tools, they don’t give you much control. That means you need to implement the control on your end by working very slowly and carefully.
Mistake 2: Using the wrong blade. Having a blade that hasn’t been designed for wood is not safe. It may cause sparks that could result in a fire if the wood is very dry, and it may slip more easily. Use a blade that is designed for angle grinders and therefore safer to use.
Mistake 3: Not checking that the blades have stopped spinning. Remember, angle grinders don’t come with an automatic brake, and that means they’ll keep spinning for a few seconds even after you have stopped applying the tool. You need to make sure that you use it in a way that doesn’t create a risk. Have somewhere safe to put it down, and allow it to fully stop first.
Angle grinders can be used to cut wood, but you need to be cautious and sensible. If used badly, they could be unsafe. Make sure you have the right blades and that you know what you are doing before you try to cut wood with this tool.

The diamond content is consistent across all segments, so you won’t have to worry about consistency. You can use this blade for cutting brick, concrete, and stone.
Turbo diamond blade
If you want a blade that you can use for a wider variety of materials, the turbo diamond blade is a great choice. It’s also suitable for masonry, including marble, granite, concrete, stone, stucco, brick, and more. You can also use it for accurate cuts, and it’s built to last for a long time. Thus, you’ll be able to cut through a lot of material without worrying much about damaging the blade.
There are several different attachments that can be used with an angle grinder to perform different woodworking tasks. These attachments can be used to sand, polish, carve, or even cut wood. With the right attachment, an angle grinder can be a versatile tool for any woodworker.
If you’re looking for an efficient way to cut wood, you need a good quality wood cutting disc for your angle grinder. There are a few things to consider when choosing the right angle grinder wood blade for the job. The type of wood you’re cutting, the thickness of the wood, and the speed of the grinder are all important factors. With the right disc, you can make quick, clean cuts through even the thick pieces of hardwood.
There are a lot of different wood cutting discs that you can purchase for your angle grinder. However, it is important to make sure that you purchase the best angle grinder wood blade for the job. The type of wood you’re cutting and the speed of the grinder are also important factors to consider when choosing a woodcutting disc.
Wood carving disc
A wood carving disc for an angle grinder can make quick work of shaping and carving wood. When choosing a disc, it is important to select one that is designed for use with an angle grinder and that is the right size for your particular model. A wood carving disc for your angle grinder is a great way to add detail and fine lines to your woodworking projects. These discs are easy to use and can help you achieve the professional look you desire.
Each type of angle grinder wood blade has its own advantages and disadvantages, so it is important to choose the right disc for your project. There are discs made of tungsten carbide, designed to prevent kickback, and more. With the angle grinder wood blade you need, you can shape and carve wood to your exact specifications.
This isn’t something that a lot of people know, but you can actually turn your angle grinder into a chainsaw with a chainsaw converter. Chainsaws are powerful tools that can make quick work of large cutting jobs. However, it can be difficult to control and maneuver chainsaws, especially for smaller projects.
Meanwhile, an angle grinder is a smaller, more nimble tool that is better suited for smaller cutting jobs. An angle grinder chainsaw attachment will allow you to use a chainsaw blade on an angle grinder. This gives you the best of both worlds: the power of a chainsaw with the nimbleness of an angle grinder.

The Best Angle Grinders for Wood Carving (Updated 2023)
Searching for the best angle grinder for wood carving? Carve out a moment to read this article first before you hit that purchase button.
Before we get into the reviews, it’s important to know that most large, heavy-duty angle grinders are meant to cut and grind metal, not wood.
However, small and lightweight angle grinders are ideal for wood carving, shaping, and sanding.
When used with the right blades and accessories, these versatile power tools excel at a variety of woodworking tasks, including shaping furniture, carving sculptures, shaping large curves, etc.
To help you find the right tool for your needs and budget, we’ve rounded up some of the best angle grinders and discs currently on the market. Each of our top picks below has been assessed based on its durability, power, maneuverability, and safety.
The Best Angle Grinders for Wood Carving
Our Top Pick: DeWALT ( DCG413B ) 20V MAX XR 4.5-Inch Brushless Angle Grinder
Lightweight yet powerful and packed with excellent safety features, this cordless angle grinder is highly versatile and ideal for carving, shaping, and polishing.
It’s a godsend when working in tight places, at awkward angles, and when you don’t want to string an extension cord all over the place.
What we like the most about this DeWALT grinder is its brushless motor that spins discs up to 9,000 RPM. It offers longer runtime and doesn’t require brush changes – ever.
You may think that 9,000 RPM is not particularly powerful, but that is plenty of torque for most projects. Still, we recommend a corded angle grinder if you want more power for heavy-duty tasks.
We greatly appreciate the Kickback Brake feature that automatically reduces the movement of the grinder and shuts it down when it detects wheel pinching or stalling. All it takes to stop the wheel is two seconds.
The main complaint among users is poor battery life, as this angle grinder drains batteries fairly quickly.
The remedy for this is having several 20V batteries, and the good news is that the angle grinder works with any DeWALT 20V MAX or FlexVolt batteries. The bad news? Batteries and chargers are sold separately.
- Brushless motor, 9,000 RPM
- Powered by 20V battery
- Weighs 3.8 pounds
- E-Switch protection
- Kickback Brake protection
- Compact, lightweight, and cordless
- Lots of safety features
- Plenty of power, suitable for most projects
Our Top Corded Pick: Makita (9557PBX1) 4.5-inch Angle Grinder Kit
The Makita 4.5-inch angle grinder weighs less than 5 pounds yet has a powerful 7.5 Amp motor, making it a highly versatile tool that can handle any type of wood carving project, small or big.
It may not be the lightest angle grinder out there, but it’s certainly lightweight enough to maneuver easily.
Thanks to its slim handle, large paddle switch, and lock-on/off feature, it’s easy to use and comfortable to hold for longer periods. And because this is a powerful angle grinder, it comes with soft-start technology, which helps prevent recoil and keep you safe.
BANNED: Woodworking‘s most dangerous tool?
Another thing we really like about this grinder is its durable design. The housing might be made of plastic (and this is why it’s so lightweight), but it’s sturdy. Plus, it has a protective varnish that seals the armature from wood dust, helping prolong the unit’s life.
The kit includes the angle grinder, a diamond blade, a grinding disc for steel, and blade guards.
Overall, it’s a versatile, easy-to-maneuver tool with plenty of power that’s perfect for wood sculpting, carving, and sanding. Many users also report that it’s great for polishing.
The minor downside for some users is that it heats up relatively quickly with continued use, but that is to be expected – no grinder is made for all-day use.
Also, while the kit is a great deal, you cannot store the grinder with the handle attached in the case as it doesn’t fit. This means you have to remove the handle, stow it separately, and re-assemble it whenever you need it. Not a huge con, but something to keep in mind.
- 7.5 Amp motor, 11,000 RPM
- Weighs 4.5 pounds
- Soft-start technology
- Extra-large paddle switch
- Lock on/off feature
- AC/DC switch
- Powerful yet lightweight enough to be comfortable to hold

Best Angle Grinder Disc for Wood Carving: Kutzall Extreme Shaping Dish – Medium 4.5-inch
Specifically designed for carving, shaping, and sculpting soft and hard woods, the Kutzall Shaping Dish is one of the best angle grinder discs on the market. Yes, the grinder disc is a little pricy, but there’s a reason for that. Well, several reasons, actually.
For one, the disc is made from ultra-durable tungsten carbide material, which stays sharper for longer compared to standard abrasive discs.
This means that you may actually save money in the long run by avoiding frequent replacements.
It’s also easier to clean as you can use a wire brush or a torch – neither should harm the teeth.
Another great thing about Kutzall is that it’s incredibly easy to control, as it has excellent resistance to loading.
There’s practically no kickback, making it safer than traditional abrasive discs. Choose the Original Coating when working with hardwood, or Extreme Coating when working with wet or gummy wood.
Many users praise this Kutzall disc’s ability to smoothly shape and cut with or against the grain on all types of wood, including denser wood. Its design also allows for quick and easy removal of wood without clogging.
However, we should mention that some users find the product clogging up too quickly and creating dust. Needless to say, a good soft-wire brush and eye and face protection are must-haves.
- Made from tungsten-carbide material
- Highly resistant to loading
- Can be cleaned with a torch or wire brush
- Available in a variety of coatings
Budget Pick: Bosch 1375A 4-1/2-inch Angle Grinder
Don’t let the cheap price fool you, the Bosch 1375A 4-1/2-inch angle grinder is a versatile little beast that can cut through almost any material, but most importantly for us, any wood, too.
Slim, compact, and weighing less than 4 pounds, it’s easy to maneuver and use for extended periods. It is ideal for folks who often suffer arm fatigue when working with heavier angle grinders.
The lock-on slide switch allows continuous operation and keeps you focused on your task. The auxiliary handle enables you to move it to either side – great for lefties and when working from awkward positions.
We also appreciate the epoxy-coated field windings, which help protect the tool from dust and abrasive debris.
With a 6.0 Amp motor that produces no-load 11,000 RPM, this Bosch grinder has plenty of power for light to medium projects.
No, it’s not the most powerful angle grinder out there, but it’s great for lighter tasks like hallowing out wood bowls, carving boards, sanding wood, etc. This said, plenty of customers successfully use it for shaping wood in furniture construction, too.
On the downside, this is a single-speed tool, and while 11,000 RPM is plenty of power for most small and medium jobs. If you want to shape large, dense wood easily, you’ll probably want something more powerful.
- 6.0 Amp motor, 11,000 RPM
- Weighs 3.75 pounds
- 2-position side auxiliary handle
- Lock-on slide switch
- Compact and lightweight, easy to maneuver
- Well-made yet budget-friendly
- Plenty of power for most wood carving tasks
Best for Big Jobs: DeWALT DWE402 4.5 Inch Angle Grinder
Looking for a powerful angle grinder for larger projects? You’ve found it.
The DeWALT 4.5-inch angle grinder boasts an 11 Amp AC/DC motor that spins at 11,000 RMP, making it perfect for heavy-duty jobs like crafting furniture. It may not be ideal for ultra-delicate tasks, but it’s plenty versatile when paired with the right wood disc.
The grinder has a paddle switch with a safety lock-off, preventing accidental start-ups. The handle, while slightly bigger than most, provides good ergonomics thanks to its oversized threading. This makes working with the tool safe and comfortable.

How We Decided on Our Picks
Power and Performance
A good angle grinder should help you safely and comfortably shape a piece of wood into something useful or decorative.
To do that, it needs to have enough power (as well as certain safety features, but we’ll get to that).
This is why we prioritized motor power and performance when searching for the best angle grinders.
We looked for tools with at least 6 Amps of motor power, which is enough for most light and medium-duty wood carving and shaping jobs.
But if you’re working on larger projects or want to be able to easily and quickly shape larger and denser pieces of wood, you can definitely go above that. Just bear in mind that the more powerful the motor, the heavier the grinder.
Size and Weight
You’ll probably use your grinder for extended periods from time to time, so you want a compact and lightweight unit.
We focused on angle grinders that are around 5 pounds, as they’re comfortable to hold for longer periods and are typically easier to maneuver.
We did pick one heavier grinder (the DeWALT is a little over 6 pounds), but that one is best suited to folks looking for a more powerful unit for heavy-duty tasks.
An angle grinder is, after all, a handheld power tool and, as such, can be dangerous and cause kickback. Even a small change in your posture might cause a grinder to get out of control, especially if you’re using a wrong disc.
For this reason, we paid particular attention to the safety features such as emergency shut-off, safety hand guard, and soft start.
Durability and Construction
Finally, a good-quality angle grinder should be well-made and durable.
We chose units with sturdy housings from reputable brands. Metal casings are, of course, the best when it comes to durability, but metal does slightly increase the weight of the tool.
Still, it’s possible to find lightweight grinders with metal casings (look at BlackDecker). Sturdy plastic is most common, however, as it’s light.
A big plus is also a protective sealing that prevents wood dust from entering the motor and damaging it.
Rely on a quality angle grinder for cutting, grinding, carving, and a host of other tasks.

Angle grinder as a wood cutter
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.
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.
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.
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.
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.
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.
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.
Makita XAG04Z 18V LXT Cordless Cut-Off/Angle Grinder
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.
- Automatically adjusts speed and torque settings
- Slow start keeps the tool from jumping
- Lock-on switch
- Very little noticeable vibration

Metabo HPT 4.5-in 6.2-Amp Angle Grinder
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.
- Lock-on switch for long use
- Lightweight angle grinder (only 4 pounds)
- The most compact of all the grinders tested
- A little lacking in power compared to other corded models
- The 6.2-amp motor isn’t ideal for all-day use

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.
- Safety includes two-stage trigger, electronic brake, and kickback brake
- Excellent ergonomics and anti-vibration
- Plenty of power

Porter-Cable Angle Grinder Tool, 4-1/2-Inch (PC750AG)
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.
The one negative worth mentioning is that vibration control isn’t top-tier, so although it can take all-day use, the user’s hands and wrists might tire.
- Top-mounted handle position
- Comfortable trigger switch
- The 7.5-amp motor has plenty of power

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

DeWALT Angle Grinder Tool, 4-1/2-Inch (DWE402)
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.
- Pro-grade capability
- Very fast and powerful
- High amperage motor for heavy-duty work

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.
Shopping for a Used or Refurbished Angle Grinder
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.
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.
