Work With Ease and Comfort With the Best Cordless Angle Grinder
When most workshop guys think about grinders, they picture the hand-held angle grinder. This multifunctional power tool can be used for many tasks, including cutting iron tubing to repair a damaged valve, carving wood to make furniture, tile cutting for a backsplash, and cleaning grout between tiles.
With technological advancement, professional power tool usage is rapidly shifting to cordless power, and as a result, cordless angle grinders are becoming more popular. The ability to work autonomously from a steady power source is highly desirable. It means you aren’t bound to wires or power cords and can readily access difficult-to-reach workplaces. Whether working with wood, metal, or stone, an angle grinder wheel will make your life significantly easier.
If you are ready to add this versatile tool to your toolbox, we have reviewed and compiled a list of quality cordless angle grinders for 2023 to help you get the desired results.
Finding Your Next Cordless Angle Grinder: A Buyer’s Guide
When it comes to purchasing a cordless angle grinder, everyone has different requirements. Some people prefer their grinders to be as strong as possible for heavy-duty work, while others prefer them to be ergonomic and comfortable to work for extended periods. You will need to consider these things to determine which grinder is ideal for you. So, here are some features of a cordless angle grinder and how they affect performance.
Angle grinders are available in various sizes, each identified by a number representing the largest diameter of grinding disc or wheel that it can manage. A 4, 4.5, or 5-inch disc will work for the majority. Since bigger discs might be cumbersome or time-consuming, smaller sizes and weights are preferable for DIY projects.
In industrial settings, professionals typically utilize larger discs (up to nine inches) when cutting through thick chunks of material. Discs larger in diameter require grinders that can withstand greater cutting forces. This means you’ll use a heavier tool that’ll wear on your hands faster than a compact angle grinder.
The rpm of an angle grinder is the standard for describing its speed (rpm). Some powerful grinders can reach speeds of 12,000 rpm, while most operate at a lower range of 5,000 to 10,000 rpm. But, the rpm number is under “no-load” conditions, which means the disc is not grinding or cutting anything but is simply spinning in the air. When the disc starts cutting or grinding, the speed drops dramatically.
A higher rpm indicates that the tool is capable can cute material with greater ease and speed, but there is an increased risk of injury due to the disc’s potential to rupture as it heats up at faster speeds. Pay attention to the disc’s maximum supported speed and use the appropriate disc for the job. For instance, if you run a disc that is only supposed to withstand 7,500 rpm at a quicker speed, it may shatter and send pieces of the grinder wheel flying.
The power output potential of angle grinders is measured in volts (V) and amperes (A) (amps). The power of a cordless angle grinder’s battery is measured in volts. Most cordless models have 18-volt or 20-volt batteries, but some have 7.5-volt or even 24-volt batteries. Most cordless power tools have a “magic number” of 18 to 20 volts, which is the best mix of price and usefulness.
The angle grinder’s guard is a very important safety feature covering half of the disc. Its job is to protect the user’s hands by stopping sparks and other debris from flying at them. It also keeps surfaces from getting damaged when working in tight spaces.
The guards on some angle grinders are movable, whereas, on others, it is permanently attached. The adjustable model is preferable because it can shield the user from projectiles in either direction and is useable with either hand. But, if the bolts aren’t secured, a removable guard could come loose. In contrast to removable guards, fixed guards are more secure and won’t fall off using a grinder.
Angle grinders might recoil slightly on starting up because they are quick, strong tools. This is especially true if the wheel is big and heavy. The motor’s recoil can cause the angle grinder to jump in the user’s hands, leading to possible serious injury. Soft-start technology decreases the output power to the motor initially, gradually rising until the grinder is fully operational. This power regulation reduces the jolt to the user’s arms and wrists and keeps the grinder from recoiling during start-up, improving safety.

New DeWALT Power Detect Cordless Angle Grinder
In addition to the new higher-powered POWER DETECT cordless power tools we discussed recently – a circular saw, reciprocating saw, and hammer drill – DeWALT is also launching a new 20V Max angle grinder, DCG415, which they say is up to 40% more powerful than its predecessor, model DCG413.
The new grinder is equipped with a 5″ wheel guard by default, and can also be used with 4-1/2″ accessories, presumably provided that you acquire and secure the appropriately-sized guard.
- 4-1/2″ and 5″ wheel compatibility
- Kickback brake (stops wheel and shuts off the grinder in bind-up situations)
- Up to 40% more power than DCG413 paired with 5Ah battery
- 9000 RPM no-load speed
- 12.2″ length
- Weighs 3.87 lbs (presumably without battery)
- 1350 Max Watts Out
DCG415W1 kit comes with a 8Ah battery, charger, and carrying bag.
Note: the grinder comes with a 5″ Type 27 guard. If you want to use 4-1/2″ wheels or cut-off discs, you’ll probably need to be purchase the appropriate guard(s) separately.
Kit Price: 279
We’re told that a bare tool option will likely be available by early 2021, perhaps sooner (late 2020).
The new DeWALT Power Detect angle grinder seems to fill in the performance gap between their 20V Max brushless 4-1/2″ angle grinder, and their FlexVolt 60V Max 4-1/2″ to 6″ angle grinder.
Here’s a list of our DeWALT Power Detect tool coverage so far:
20 Комментарии и мнения владельцев
“The new DeWALT Power Detect angle grinder seems to fill in the performance gap between their 20V Max brushless 4-1/2″ angle grinder, and their FlexVolt 60V Max 4-1/2″ to 6″ angle grinder.” But what happens when a consumer complains that they now want something to fill the performance between the Power Detect and the FV grinder. Just makes me ?♂️
Another one? Or a brand new completely different line with 13% performance boost? If a consumer has to buy a new tool and a specific 8ah battery to realize the boost, then why? You already sell FlexVolt
Like we’ve discussed with the other power detect tools I suspect what will happen over time is the older models will cease production soon, say in a year or 2. OR they will only be made in red color – another easy pitch is to make them all craftsman models recycling the old drawings and specs etc. I mean they are good tools and they would be excellent in red color. While the new DeWALT standard will be these power detect models.
60v vs 20v, both with a fast charger, and 1 battery (6ah vs 8ah) is 329 (at HD) vs 279 (At Lowes) right now. So it’s about 50 or 18% cost difference for flexvolt vs this new power detect model. The watts out is 1350 vs 1700 (from DeWALT’s site) That’s a 26% increase in power on the 60v compared to 20v. Both have the same 3/1/90 warranty. The current 20v brushless is the DCG413, but I can’t find any kits with a fast charger, just a regular one. The price is also plus or minus 20 from the new DCG415, but DCG413 seems to be kitted with the newer 3ah battery while the DCG415 has the 8ah one. DCG413 20v – 850w – 288 DCG415 20v – 1350w – 279 DCG414 60v – 1700w – 329 I have several of the brushed DCG412 and one DCG413. The brushless has more speed, which is one reason I got it: for polishing aluminum. For brushless models, I don’t see a reason to get the DCG413 with current pricing, unless it is for the tool only and without battery (about 100 less) where the power detect isn’t available tool-only unless though a reseller. I checked ebay and found zero. I probably use the 20v more than I do the 60v, but purely so that I don’t have to keep swapping the cutting disk, grinding wheel and wire wheels on and off. The 60v removes material like nobodies business. The head can also rotate 90 degrees to put the wheel on either side of the grinder, though it takes removing 4 screws. However, this points out a flaw in the 60v: there is not a screw boss for the aux handle in the top of the head, which would be the side when rotated. The 60v is physically larger, so if size is of major concern, may need to drop to the 20v options The 60v battery only works one way though. Can’t put a 20v battery on the 60v grinder, while the 20v power detect could use any DeWALT 20v battery, even the 1.3 and 1.5ah ones. for reference, they only last perhaps 5 minutes on the brushed version, and maybe 3 minutes on the brushless in my use cases. However, if you already have several 20v batteries, you can go for the bare tool DCG413 and save 200 over the cost of the 60v kit. For the 50 difference all-in, I’d probably get the 60v version if I had to limit the choice to only one grinder or was interested in possibly getting more 60v tools in the future. Otherwise, the tool only DCG413 would probably be the better overall choice until the tool only DCG415 power detect is available. From a pure price point, this sure seems to kill the current DCG413 brushless grinder. power and more battery for the same price? On the plus side, the DCG413 will probably be cheaper and/or clearanced out which means possible deals in the future.
Wow stuart, DeWALT must really be pumping money your way to promote this new line. Can’t go a few days without another post about it.
Wow John, I wish!! From your mouth to their ears! I posted about the first 3/4 tools separately, and so it didn’t feel right to bury this within the other post. I guess you’d prefer I don’t bother with new information or details of potential interest? Should I not continue with updates on tools that readers seem interested in hearing about?
I think the correct response is “If I got 5 for every time someone called me a paid shill…I’d have enough money to buy the new DeWALT DCG415W1 kit, which comes with a 8Ah battery, charger, and carrying bag.”
All these tool companies need to start focusing on better battery placement. I know it’s easier to say and harder to do, but 90 deg to the body would definitely be annoying to me and my forearm. A good example is the Bosch 18v multi tool with battery under and parallel to body. And the Milwaukee barrel Jig. If anyone says this can’t be done on a grinder, polisher or a larger disc sander, I’m not buying it.
Glad to hear they are upping the specs. I have this 20v and the larger flexvolt grinder as well. The 20v could use a bit more a. Ergo’s were good once you removed the stupid trigger saftey. Battery life was decent with a 5ah. I wonder how the 8ah battery effects the balance of this 20v tool? Ive pretty much standardized on the 5ah 20v battery. I see the 6ah 20V as useless as its the same price and size as the 6ah flexvolt but won’t work on 60V. Ive not seen an 8ah in person but have several of the 9ah flexvolts. If they are reasonably close in size/weight I will just stick with 9ah. Im assuming the power detect feature works with flexvolt operating in 20v mode?
“Ive not seen an 8ah in person but have several of the 9ah flexvolts. If they are reasonably close in size/weight I will just stick with 9ah. Im assuming the power detect feature works with flexvolt operating in 20v mode?” Good news: The 8ah is a fair bit lighter and a bit smaller (about 2/3s) than a flexvolt 9ah. I hope these become the “norm” with DeWALT kit as they are a good balance. Bad news: The 9ah Flexvolt in 20v mode doesn’t work any better than a 5ah 20v. Well neither of my 9ah Flexvolt batteries. One is about two and a half years old and the other about one and a half. I’ve made a video showing the difference in speed on the new DCD998 “Power detect” drill https://www.YouTube.com/watch?v=WI3u-y_Gbhs Newer Flexvolt 9ah batteries and the 12ah (although these are prohibitively expensive) may well work, but older ones don’t.
The original (pre 2019) 9Ah FlexVolt batteries and 6Ah XR 20v batteries used 20700 Sanyo cells, not the 21700 Samusungs that are used currently. That was my biggest question as to whether or not they would also give the boost, and you are saying they do not. Not to doubt you, but I am still waiting on confirmation from a DeWALT rep. Either way, thanks.
The date code on the 9ah Flexvolt battery I tried in the video is 2018 date stamp and that’s my newer battery, so it will have the older cells. My older 9ah Flexvolt battery is a 2017 date stamp. I’ve always found that 2017 battery gives about 3/4 of the runtime of the 2018. I have the flexvolt 9″ concrete cutter and it also overheats quicker. The 2018 battery has 6 additional metal tags on the top, I’m not sure what these are for, but it’s how I know which one is the “good” one.
If you’re curious and would like to know what cells you have, check for silver tabs on the top of the battery. They extra heat sinks. The 21700 based batteries have them, the 20700 based do not. Pics: http://forum.toolsinaction.com/topic/14357-new-9ah-batteries/
“I see the 6ah 20V as useless as its the same price and size as the 6ah flexvolt but won’t work on 60V.” The 20v XR 6Ah is NOT the same size as the FlexVolt 6Ah. 20v XR is a 10 cell 21700 based battery (same as the new 8Ah XR), FlexVolt is a 15 cell 18650 based battery. So there dimensions are a bit different. And the cells inside are what make it superior to the FlexVolt, imo. I don’t use anything but the 9Ah or 12Ah batteries in my FleXvolt tools, so if anything I would say the 6Ah FlexVolt is the more useless of the two.
What is this…the 7th DeWALT battery angle grinder? Still without variable speed. It’s like they don’t realize you can use an angle grinder for other things besides cutting metal. And speed is directly related to the safety of your situation. Try fraying carpet with a wire wheel on this or the Flexvolt… Then call me from the hospital. As far as I know, Makita is the only ones with variable speed battery grinders, and they’re awesome!
Top 3 Cordless Angle Grinders ǀ DeWALT vs Milwaukee vs Makita
No metalwork or mechanic’s shop can function without an angle grinder. If you work with rock and concrete, an angle grinder is also going to be an important part of your power tool repertoire. I’d say we all need one, DIYers and professionals alike. There are plenty of best cordless angle grinder reviews. We’ve cut to the chase, choosing only the top three models in 2021.
This is not a review of the cheapest cordless angle grinders. Far from it. This is about buying the best. It should come as little surprise that models chosen for this review hail from the top power tool bands, especially in the cordless tool arena.
The DeWALT DCG412B 20V MAX 4½” cordless angle grinder is probably the most popular and is a no.1 best-seller on Amazon. As a long-time devotee of DeWALT 20V MAX tools, I’m leaning toward the DCG412B as my top choice. If the DeWALT 20V MAX battery platform is your preferred choice, this grinder will obviously appeal to you.
That’s not to say that the other contenders for the top 3 cordless angle grinders are any less magnificent. Makita 18V LXT tools are synonymous with high-quality, superb durability, and incredible technology. The Makita XAG04Z 18V LXT 4½” cordless angle grinder is a worthy competitor to the DeWALT DCG412B.
The Milwaukee (2783-20) 18V FUEL is, as many would have anticipated, is the most expensive of the three cordless angle grinders chosen for this review. Milwaukee fans are less concerned about price and more inclined to look at the quality and superior performance. I’m sure this little beast will not disappoint on this front.
DeWALT DCG412B 20V MAX 4½” Cordless Angle Grinder
- 8,000 rpm motor provides high power for cutting and grinding applications
- Quick-Change Wheel Release allows tool-free wheel removal without the need for a wrench
- Tool-free guard allows for quick and easy guard adjustments/positioning
- 2-finger trigger switch with lock-off button for convenient activation and easier gripping
- 2-position side handle offers greater control, comfort, and versatility
Even though this is not a DeWALT XR tool, the DCG412B has amazing power, especially when you consider that it uses the old, brushed motor. Without the XR branding (and upgraded XR brushless motor), the DeWALT DCG412B is delightfully cheap for a high-quality tool from one of the top brands. It is excellent value for money.
I really like the large comfortable handle and two-finger trigger. The side handle can be mounted to either side which is great for varying working positions. This is easily one of the most comfortable grinders to use and it weighs only 4-pounds.
Being a DeWALT tool, I’m always going to love the DCG412B. DeWALT 20V MAX tools have certainly grown on me over the years. I also greatly admire their customer service and fantastic 3-year warranty, 90-day moneyback guarantee, and 1-year free service plan.
Makita XAG04Z 18V LXT 4½” Cordless Angle Grinder
- Automatic Speed Change technology adjusts speed and torque during operation for optimum performance
- Active Feedback-sensing Technology (AFT turns the motor off if rotation of the wheel is suddenly forced to stop

I’ve always been amazed by Makita technology, especially when it comes to safety and durability. Like all the Makita tools I’ve owned, I’d expect the XAG04Z cordless angle grinder to endure any type of punishment and probably outlast most others.
The list of cool engineering, intended to make this one of the toughest grinders is expansive. Extreme Protection Technology (XPT) is a Makita hallmark and really helps extend tool life. By super-insulating the tool against dust and moisture, the machine can tolerate extremely tough conditions without damage or excessive wear.
The Makita XAG04Z utilizes a brushless motor with electronic controls. This makes it incredibly powerful and super-efficient, providing fantastic battery times. It also adjusts the speed automatically to optimize performance. A great safety feature is the active feedback-sensing technology (AFT). If the wheel suddenly stops, the motor will automatically switch off, preventing a dangerous kickback.
Makita Rapid chargers have always been amongst the best. Electronic monitoring prevents any damage to the battery, whilst providing about the best charging times. Extra cooling for the battery and the motor also ensures the best battery time and longevity.
The Makita XAG04Z is undoubtedly an incredible cordless angle grinder. Makita is possibly the best brand for indestructible tools. They really are as tough as nails. This machine is also packed with great technology, improving performance, safety, and efficiency. A testament to Makita durability has to be their fantastic 3-year warranty.
Milwaukee (2783-20) 18V FUEL 14½” Cordless Angle Grinder
- Rapid Stop braking feature stops cutting disks in 0.9 seconds, flap disks in 1.3 seconds and grinding discs in 1.5 seconds
- POWERSTATE Brushless Motor: Delivers maximum power and up to 10X longer motor life
- REDLINK PLUS Intelligence provides optimized performance, electronic clutch, and overload protection using total system communication between tool, battery, and charger

- POWER TO GRIND: World’s first cordless braking grinder with corded performance.
- DURABILITY: Same metal housing gearing system as legendary high performance corded grinders
- 100% tool-free: Make all accessory changes and guard adjustments without a wrench for increased productivity
The majority of power tool buyers may consider Milwaukee to be an elite brand, too expensive. There are those who don’t mind the price. Milwaukee tools are exceptional and are often the first choice for professionals, wanting extreme durability and the best tool performance. The Milwaukee 2783-20 M18 FUEL may be the best 14½” cordless grinder on the market.
The M18 FUEL battery platform, combined with REDLINK electronic technology is the pinnacle of advanced battery engineering. The electronic clutch is truly sublime, as is the battery monitoring system which ensures prolonged battery and tool life.
Milwaukee cordless tools are always at the top of the power rankings and this grinder is no exception. The POWERSTATE brushless motor gives you the grunt for the toughest jobs. It is also extremely efficient, getting the most out of the 18V FUEL battery.
Rapid stop braking is one of the big selling points that Milwaukee use to promote this grinder. It’s something I really like. A disc brake saves a lot of time. It can become really frustrating waiting for the disc to stop before you can safely put the tool down.
Generally, Milwaukee tools are heavier than others. I wasn’t really that surprised to see that the 2783-20 cordless angle grinder weighs 6.1 pounds – noticeably heavier than other two grinders in this review. I guess, the heavy duty motor, gearbox, and clutch will add some weight.
You can’t beat the Milwaukee 5-year warranty for the tool. Even the 3-year battery warranty is possibly the best in the industry. In the end, paying extra for the Milwaukee 14½” cordless angle grinder buys you great peace of mind. You know that you’re getting a top-quality machine, with fantastic technology, and the best warranty.
