Milwaukee has come out with a new M18 Fuel brushless die grinder, model 2784-20/22.
Milwaukee says that the new M18 Fuel 1/4″ die grinder delivers corded performance, and can actually remove material faster than a corded grinder. Runtime is up to 20 minutes on a single M18 XC 5.0Ah battery charge.
They say that it can remove up to 2x more weld than any cordless die grinder on the market.
Features & Specs
- 20,000 RPM
- Lock-on slide switch
- Overload protection
- Electronic clutch
- Soft start motor
- 18″ length
- Weighs 4.7 lbs
- 5 year warranty
Die grinders are used for metal fabrication and in other related metalworking-involved industries, for material removal where other grinders won’t work as quickly, easily, or effectively.
I suppose this was a logical progression. Milwaukee already offers M18 Fuel brushless angle grinders, which are quite good by the way, and also a non-fast-braking design. Grinders, oscillating tools, sanders, and other continuous-use tools benefit from the boost in runtime and power, but at a cost.
Price: $399 for the kit (2784-22), $199 for the bare tool (2784-20)
The kit, 2784-22, comes with (2) 5.0Ah battery packs, an M12/M18 multi-voltage charger, 1/4″ collet, wrenches, an extra dust cover, and case.

$199 seems reasonable for the bare tool, but you’d probably really want to stick to using 5.0Ah battery packs, given the “up to” 20 minute runtime specs. That’s not too bad, actually. I remember once using a cordless cutoff tool for less than 5 minutes when the battery gave up.
If you use a die grinder frequently, or even on occasion, would this be a welcome addition to your toolbox?
Die grinders aren’t really a “grab and go” kind of tool. My own [infrequent] use has been more or less for workshop-based applications. I’d expect that someone using a die grinder regularly would prefer an AC electric or pneumatic-powered tool.
20 minutes is a lot if you’re just deburring a pipe or cleaning a small weld or two (right?), or doing any number of small minor tasks.
But what’s your use like? Long stretches of grinding, or shorter sprints?
Oh, and they say that the PowerState brushless motor improves the motor life by up to 10X, compared to the competition.
There’s one more quick fact that’s buried in the press release. The new brushless die grinder features the same metal housing and gearing system responsible for delivering the legendary performance and durability found in Milwaukee’s high performance corded die grinders.
What this means is that it’s built as solidly as their corded tool, and should deliver comparable performance.
It’s good to see Milwaukee continuing to push forward, and I like this trend of corded-adapted brushless tool development. I think they started doing this with their M18 Fuel brushless deep-cutting band saw.
Hmm, so this is how you sell cordless tools to shop-based corded tool users. But is it convincing enough?
20 minute run time . I’ll keep the corded makita
Maybe for you it is but if I have 2 battery’s with me on the job site I can run 40 mins non stop and thats all the time I need. and I’m sure those 9.0’s will last a lot longer…
I do commercial electrical work, and i could see this coming in handy if i was doing alot of 2-4″ conduit.. last time i was doing 4″ i wished the foreman had one of these.. filing the ID of that stuff sucks
Not much of a welder (future skill I’d like to learn) so I couldn’t see myself using something like this.
Any word on the mid-torque wrenches?
For as infrequently as I use one, my pneumatic one is much smaller.
Not a super common tool, but its nice to have a cordless option. Milwaukee has to be catching up to Makita in cordless 18v tools if you don’t count all the drill and impact models Makita has.
I don’t see this replacing shop work obviously – but I like that it exists. I could totally see using this on an airplane on the line or fixing hard pipes in the field. This is one of those items where something akin to the flexvolt either or situation would be equally useful. IE ability to plug it to a cord. or run it battery
OH and metal workers might like this for install work/rework. IE you’ve fabed that gate but when you install it 30 miles away it would be nice to knock down this weld or ______. It’s going to have it’s uses.
It does not look to have a way to adjust the speed. That would be the deal breaker for me. You need slower speeds for sanding rolls, burrs etc.
If it has a speed adjuster I’m all in.
I was mildly surprised to see a slide switch on it – maybe there is a dial?
I expected to see a variable speed paddle on it – with a lock out.
I have the 18v version Bosch makes and I don’t use it often but there’s been plenty of times during a project that this type of tool has absolutely saved me and allowed me to continue without loosing my temper. haha Actually I just used it a few weeks ago to cut back some metal rafter brackets that were too big. That saved me a trip back to Lowes.
I think Milwaukee needs to come out with an adapter like Dewalt has for the flexvolt miter saw. I think Milwaukee has enough tools available now to make it worth it.
And yeah, the freedom is cordless is always nice, but if you’re at the point in the construction stage where you have power to charge your batteries, it makes sense. However in order to make it worthwhile it would have make it for around $50 or less.
Just take my money , when I need a sraight grinder , I’m already in. tight spot , last thing I need is a cord ! I’ll hrab one for sure !
No variable speed kills it for me.
Yah, lack of speed control is a deal breaker.
Depends on your industry. For me, it’s perfect(marine services). I’ll be buying one the moment it hits the shelves. 9/10 die grinder usage for us is a quick tune up, deburring the inside of a hole, grinding out fiberglass around a cut out, modifying aluminium panels, adding notches, radius etc. All of these are <20 min jobs. I worried a lot buying my first cordless grinder. half the time now I throw a compact(1.5AH) battery on it, slip a second in my pocket if I think I'll be a while, and go to town. Love the light weight and ease of use. The telling factor for me is that in a shop with 5 guys, and a half dozen corded grinders, all pre-loaded with the right grinding/cutting disks, the first tool everyone reaches for is the cordless one. The no power cord is a life saver in tight awkward working conditions, and rarely do we need more than a single battery swap to do a job.
I’m a metalworker and I tend to use a die grinder as much or more for non-ferrous jobs; perhaps aluminum as mentioned above but also for cutting crude slots in plastics and other things I can’t remember.
Regardless, it’s really a sizeable mistake to think of this as a metalworker’s-only tool. That’s like saying wrenches are ONLY for mechanics or screwdrivers are ONLY for carpenters.
+1. After all, a Dremel is just the baby brother of the die grinder.
Why would I buy a cordless tool that can only run for 20 minutes on a 5 hr battery?Not much getting done in 20 minutes. For in the field deburring or filing purposes, get a die grinding bit & put in your drill chuck. Been doing it for years & it works. I do metal fab in my off time, & I would never fathom using a cordless die grinder. Especially if 20 minutes is the max run time. I’ve spoken before about this garbage Milwaukee keeps making. Its just like the one key garbage. Other than very minimal metal work or deburring other materials, i don’t see a use for it. If you have the power to charge the battery, why wouldn’t you use a corded or pneumatic? A die grinder is a 99.9% shop use tool. Thats why everyone uses pneumatic or corded & why hardly anyone’s r&d dept. has wasted the time & money trying to develop a cordless. No speed control either. Not all materials require wide open applications. You can damage something. What’s next from the line of useless Milwaukee tools? An 18v lathe? An 18v bench grinder? An 18v welder? Some thoughts and ideas should remain just that, because not all thoughts and ideas are good ones.
There’s been enough demand for several brands to offer cordless die grinders, so obviously there’s enough value in a brushless one that’s more powerful and longer lasting than brushed motor models.
I wouldn’t call this garbage.
Technically using your drill as a die grinder coids the warranty.
You seem a bit butt hurt.
Milwaukee is making leaps and bounds in the cordless race.
I could see a use for this as a mechanic.
Only takes that one time to save your ass and the tool paid for itself.
For reasons that make absolutely no sense, Milwaukee seems to think that corded tools & pneumatic tools ain’t good enough. And that a half-assed cordless version that costs twice as much would be better. And I ain’t talking about a matter of convenience. I’m talking functionality. They think everything should be made into a cordless, even if it can only run for 5 minutes. The worst part is that they double the price & think that they’re doing right by the consumer that may find a use for them by trying to convince them that they don’t have to drag a cord around, but the run time and power is significantly reduced, no matter what amphour battery you have. When its dead and you have no power to recharge it, what then? Milwaukee is really pushing the envelope as far as manufacturing useless shit. The heads of their r&d need to get their brains p and their ass wired together. I used to be a big fan of Milwaukee,but when they started all the cordless junk & jumped ship to China & gouged their prices more than anyone else, I ain’t looked back.
I understand that several manufacturers make them. But that certainly doesn’t mean that there is a high demand. How many tools are thrown into production just because the competition makes it? I wonder? I own an old B&D corded die grinder. Solid aluminum & all steel parts. Badass tool & it can take a beating. It fell 7 stories while renovating a hotel. The only thing that broke was the bakealite trigger and a small fracture to the solid metal housing. I still use it to this day. And you call milwaukee’s die grinder legendary. Man, please. Big deal they used less plastic, you’re still only getting 20 minutes run time for a premium price that doesn’t equal production output. How the f__k can anyone be convinced to piss away $200 more for the kit with 2 batteries & still not even get a full hour of production. But I can buy the “legendary” 11 amp corded which costs the same as the bare cordless? WTF is going through their heads when they think this stuff up. Damn!
Italics mean it’s their words. I do that when quotes don’t seem fitting, and a blockqoute is too much. They called it legendary. I had never used their corded grinder before.
I’ve been running ToolGuyd for more than 8 years now, and in that time I learned that there is reasoning behind everything a brand does.
Sometimes that reasoning is obvious. Other times it’s not.
You complain about every single new tool that hits the market. “This cordless tool sucks, that one is garbage, the new tech useless,” and so forth.
Sometimes you make interesting points. Other times, all I see is negativity. Frequently, I get complaints about your inclination towards colorful language.
Sometimes with new tools I can see direct benefits to my own use. Other times I can see benefits for other users. It’s rare for me to come across a tool that doesn’t make sense, and when I do I can rely on readers to share their insigets.
There is absolutely a market for this tool. I’m not a target user, you’re not a target user.
A few years ago, I didn’t think all jobsite radios should have had Bluetooth connectivity, and never saw appeal in iPhone docks. Today, with Bluetooth tech being a lot more affordable, is becoming more common that AM/FM tuners.
But I didn’t think Bluetooth tech was garbage. It had its place at the time, in higher featured radios.
My Dad had an older corded drill and corded jig saw. In theory, the metal construction should be better. In reality, modern tools are leaps and bounds better in every way, except perhaps durability, but that’s a compromise I’m willing to make.
There are tools that make me think “what the he’ll were they thinking when they came up with this?!.”
This is not one such tool.
Maybe they don’t plan to sell a lot, which is true for certain tools. In those cases, costs will be higher. And part of the deeper strategy might be to lure users to the M18 lineupromo.
If a user finds a tool they could really benefit from, and buy into the cordless platform, they might be more likely to add more tools and accessories to the lineup.
Let’s say you really like the curly fries at a restaurant. What are the chances you’ll go there for lunch and only get the fries?
I wish that the government at my work place would buy this tool for us, it would be such a saver. We have this Milwaukee corded and a Dewalt , 99% I take this one because of superiority of cutting. It also takes abuse a lot but still doing strong after about 5 years of daily use.
When you need to go in the cooler to cut the floor chain 200 track, having this cordless will be such a help, as you don’t need to carry an extension cord or two, which also want be tingling while you cutting things in a confined space on the floor or so. 20 minutes of run is more than enough for its purpose of cutting heavy metal on a distance from a workshop.
Dude, sorry about the colorful language. I’m just trying to make a strong point. The technology is at its best today, but not in the aspect of monetary value is it incorporated with a usefull purpose. But when I smell something that stinks, I gotta speak on it. That’s just how I am. Yeah the technology is great, but it absolutely has nothing to do with it being a well-built tool. Let’s be honest, there’s nothing well-built about plastic when it comes to tools. They could use carbon fiber & sell it for the same price but they choose not to because the profit margin wouldn’t be as great. They could use all metal components & parts to build the mechanisms that make it run. They used to, but plastic ruined that idea. I know there’s nothing any of us can do about the price they set. The problem is how is it that a tool that runs on a battery with a very short run time warrant more $ than an ac electric model that runs flawlessly until you unplug it, which is certainly not the case with battery power which depletes in power as the cells lose their charge. Other than not having to drag a cord around, what else about a cordless tool makes a battery & charger & tool worth 25 to 75% more than a corded tool? Its certainly not the wireless tech they are adding to them. I don’t see any valid point to any of it. If the tech gave it more power & battery life, I could possibly have a different opinion. They got the technology to do it, but again its not good for their profit margin. The days of a company caring more about how well-built their tools are than their profit margin are obviously gone. And for some reason Milwaukee seems to be at the forefront. But its not just them. And as far as complaints go,here it is. As long as product quality & durability continue to get worse with the exception of some technological advances and the fact that the price gouging is getting worse for an inferior product that is not built to last with the strongest and best materials instead of the cheapest GLOBAL MATERIALS and manufacturing a well-built product is more important than profit margins, we should all be complaining about it. We should expect the best for the money they ask, but that ain’t what they sell us, is it? Somebody has to speak up cuz it used to not be the way that it is nowadays. Its truly a damn disgrace & shame.
When is the last time a brand came out with a new corded drill? Reciprocating saw?
Tool brands are strongly guided by what users are buying and asking for.
Cordless is a huge industry, and that’s where a lot of users are spending their money. As a result, that’s where R&D funds are being funneled towards.
There has been progress in cordless tech, in pretty much every tool category.
No, this die grinder isn’t revolutionary, and yes it’ll only deliver 20 minutes of runtime on the largest M18 XC battery out there.
A few years after Milwaukee came out with their ForceLogic knockout punch tool, I was talking with the product manager at their media event. They had come out with a new smaller and more affordable lower powered unit, and said that they sold far more of the larger sized one than they expected. When talking about some of the different usability aspects of the two units, such as the quicker setup on the smaller one, it was clear that they cared about the product.
There are a lot of tools out there where the bottom line and profit is most important to the company.
Milwaukee likes to try things new. One-Key isn’t for everyone, but it’s an option. In the other post about the Mid-Torque impact wrenches, someone asked when a One-Key version will be out, because they want to customize the torque and speed settings.
I’m not as “tinker with my tools” kind of person as I thought I’d be, but One-Key controls and customizations still holds some advantages.
What makes a cordless tool cost more? There’s increasingly greater complexity, there are R&D costs to recoup, and there’s an initially high investment that goes into setting up new tool production (injection molding plates), and so forth.
Ultimately, yes, it’s about money, but that means chasing after what users are spending their money on, or will spend their money on.
Apple hasn’t updated their Mac Pro desktop computer in several years, but there are small revisions to their laptops every year and major revisions every few years. There’s a new iPhone every year, and a major redesign every 2 years. Samsung and other mobile device makers also have annual update cycles. It’s because that’s what more people are after.
I’ve spoken to a lot of product managers from a lot of brands, and most are after designing and producing good tools.
When I see this die grinder, I think “okay, it’s something for those users who have been asking for a brushless cordless die grinder.”
As for carbon fiber, there are problems with using that for things like cordless tool housings. For one, carbon fiber is going to be brittle and less impact resistant, due to its rigidity. Second, it could pose potential electric shock hazards. But most of all, getting it right and looking good would cost a fortune. There would need to be new and novel mounting methods, the overmolding process would have to be different.
They try new things because they can, and because there are users interested in the products. With One-Key, I’m sure they did their research to make sure they weren’t coming out with something that nobody would want or buy.
Will One-Key turn out to be useful? It remains to be seen.
A few years ago, LED worklights on drills and drivers? They were pretty lousy. Now, design tweaks have made them very usable. Some brands offer different brightness levels, independent operation (Dewalt), or the ability to turn them off, and others still have single LED designs that are *just there*.
Not everyone is into cordless tools, but cordless is a major driver in today’s market.
You talk like the only thing that can improve a power tool is todays technology. Lion & brushless have definitely improved performance. But thats it. A 6 amphour battery or some bs wireless connectivity isn’t leaps & bounds better than one without it. How many corded tools are brushless? How many corded tools have all this bs tech? And how the hell does a smartphone compare to a 18v power tool. Terrible analogy. Pineapples & oranges. And why the hell does a power tool have to be updated every year? Why can’t they just make it right the first time? As far as why a new corded recip saw or drill etc isn’t released every single year is because they have to build it right the first time when they come out with a new design. Therefore they ain’t gotta release one year in year out. Here’s the most important question of all, why are cordless tools and batteries manufactured for the sole purpose of being disposable? But costs significantly more than any corded version? When did a disposable battery with a definitive limited lifespan become more valuable than an entire tool that has a cord, which if you use it correctly can last for many more years than any battery or battery powered tool? How can you buy & try to talk some sh_t about complexity or r&d recoup, plates for cheap plastic injection molding (not die-casting), investments for inferior manufacturing processes & they intentionally charge the people buying these products more money? Are you fu__ng kidding me! I’m sure they appreciate you being one of the yes men. I’m sure they’ll keep hooking you up with freebies. Good job. I’m done with it.
Falling back to colorful language and personal attacks doesn’t help your arguments one bit.
Cordless vs. corded isn’t dictated by what you, I, tool brands, or retailers want to be true, it’s dictated by users’ purchasing decisions. Pro users and DIYers alike are spending far more money on cordless tools than corded ones.
Battery packs are not disposable, but yes they do need to be replaced after a certain number of years or certain number of recharge cycles. Most tools are wearable.
For tools that I use often, the cordless convenience, features, and performance justify the added cost. For tools I don’t use often, or where there are features or performance benefits, or those I plan to use in a fixed area, sometimes I go corded.
I’m not being a “yes man,” I’m telling you how I see things. Not that I’m always right, but I’ve made an effort to understand the tool industry.
The point is not everyone works in a shop. I’m a crusher mechanic and the extra time it takes me to get my welder running and get all the extension cords out time and time again through out the day eats up alot of time. I rarely use my compressor now days cause all my m18 tools are just as powerful as my pneumatic. My first batteries were the 4.0s and they still run just as strong as when I first got them 4 years ago, I also beat the crap out of them because I use them daily. Everything corded is bulky and heavy and just a pain in the ass. It just depends on the application and what you do for a living. But battery powered has come along way and most people in my indusrty use battery over corded and pneumatic. I still use them when I have a bigger job but prefer battery. I bought a 9.0 amp a couple months ago and still have yet to drain it. I used it with my fuel grinder to cut a 3 7/16 shaft for a tail pulley in half and still had a bar left. And also battery isn’t double the price unless you buy all your corded stuff at harbor freight. I own i.r Chicago pneumatic, Matco, mac and so on. Trust me I have 2 matco die grinders ones extended and ones not they cost alot more than 200 a piece. Like I Said I use it because it makes my job easier and faster. Plus it can be repaired just like anything else.
GoodnightJohnboy. Do you use tools in a commercial setting or a DIY one? I’m not trying to be rude, this really does make a huge difference in how you view the benefits/drawbacks of technology changes and tools. In my line of work we push the tools right to their limits in steel, cast iron, fiberglass, plywood etc, all day every day.
For example, the so called disposable battery packs? We use them all day, every day. I bought my first Milwaukee cordless tool in 2008 when I was working my first job in the industry. It’s still in use today, many corded tools having died along the way. One of the first two M12 batteries I bought finally quit working in December. That’s 9 YEARS of service. All our tools share the same battery platform, and any time I want I can throw a few new batteries in the mix, they’ll still run on the same chargers, still fit all the tools. I spent weeks charting out all the pros and cons of the different brands, and in the end Milwaukee covered everything I needed, and most of what I wanted and it was the best business decision I’ve ever made.
I see shops all the time with employees farting around arguing over outlets, running cords, unplugging cords, finding cords, cutting cords, driving over cords. No thank you! nevermind the electrocution hazards working around water.
In the other local shops that do run cordless, they buy what’s on sale. So there’s a mix of charger brands(usually ridgid, ryobi, new and old style Dewalts, all in the same shops), and never enough batteries, people tracking down who has the last of a given type. Wasting more time, and time is money.
The proof of this is that even though I ran plugs every 6′ around the shop and have easy access cords on all of them, time and time again employees and myself will grab a cordless tool, and a fresh pack off the charged battery rack before messing around with that.
I’ve replaced many power cord plugs, even had to tear down corded tools to sort out the wiring connections when they’ve failed.
In the 9 years so far I’ve been using Milwaukee tools they have never let me down.
On average I send 2 tools a year in for repairs, in a bad year I might send in 6. They’ve never asked me for anything more than the money for shipping.
We are incredibly hard on our tools, running a 4″ hole saw through 1″ thick fiberglass and aluminium and plywood on an m12 brushless drill is definitely at the limits of what anything that size should withstand, but they’re still going strong. In October I was seriously considering buying myself a new set, because I thought there wasn’t any way they weren’t nearly worn out. I bought an M18 compact kit instead, and quickly fobbed that off on an employee who was happy with the new tools smell and to give me back my well used FUEL set.
I wouldn’t want more metal on the housings, don’t want the weight, don’t want the horrible hand numbing in the cold. We work in rough conditions, the tools get dropped, both from heights and often into water(wouldn’t want to try that with a corded tool) access is always a pain, and when you’ve finally crawled deep into the belly of a boat the last thing you want is to have to turn around and plug in a cord that fell out. Plastic gets ugly but it absorbs a ton of abuse, never rusts and never corrodes. If the plastic they are using is good enough that a single pair of fuel tools has lasted virtually my entire working career, and I still have two of the original three batteries in rotation, more power to them for using it! It’s easier and cheaper to produce the raw materials(less environmental damage) and the price of the tools is low enough that a shop can afford to fully equip on it.
I have videos of the 3000lbs of cast iron radiators we had to saw up to get out of the shop when I bought it, all cut up with the plain old generation M18 hackzall, couldn’t get the corded Bosch at the right angles to work on it.
The m18 oscilliating tool? We’ve burned up 80 blades on it so far, including bosch carbides and mostly Imperials. Never misses a beat.
The m18 cordless vacuum? Still on it’s original washable dust filter.
I’ve worn out 3 sets of hole saws, dozens of sets of bits and the drills keep going.
I’ve had brushless tools outlast corded brushed ones. Brushless is a fantastic upgrade by the way, replacing brushes is a pain in the butt, maybe not one relevant to the average home user with a single drill and impact driver they use on weekends, but when you’ve got 6 guys and 40 tools in use, it becomes a chronic irritation. For example just this week my corded water pump bit the dust. This was a top of the line 300$ unit, and all it does is pump water, it’s well treated, the impeller lubed and stored out of the pump every winter, never let the motor get wet. The manufacturer ignored me for several days and finally told me it was obsolete and that I should buy a new one.
They got that right, and when I do it’ll be another Milwaukee. So I know that the next time it fails, I can send it, and it will come back working.
A manufacturer who stands behind their products like that is the only way to go in a business where you rely on your tools every day.
The next step for me, in around 5 years will be to sell off all my old tools which will be out of warranty and aging substantially and switch to Onekey(hoping it comes to the M12 platform as well by then). That will cut down on the issue of an employee disrupting everyone else looking for a specific tool, they can look it up on their phone and find it in one shot. Fiddling around and tweaking I couldn’t care less, but tool tracking and inventory is so valuable.
The only dud I’ve ever had is the m12 rotary tool. It’s got to be the sorriest piss-poor excuse for a dremel I’ve seen. Even the 20$ jobmates last longer. Milwaukee to date has got several earfuls from me over it, especially the time it lost speed control, wouldn’t shut down and wound out the rpm until the disk exploded in my face cutting my forehead badly. On average we get 6 hours of use before I send it back(I don’t bother to send it back anymore).
Any idea when these will be available ?
Any thoughts to any other Fuel tools coming out this year? Such as a multi-tool? Trying to hold off buying any tool that might get the Fuel treatment this year.
Can’t go wrong with the m18 multi tool even as it is. After 80 blades I can say it’s a tough tool. It runs full speed and heavy load most of the time we use it. We can cut an entire deck out of an 18′ boat in 2 batteries.
I already have had one (up til Christmas), but never mind have something better. I guess I’m more surprised they let Dewalt have one, without having a brush-less model themselves. I figure it must be coming soon…
Glad to see cordless tools reaching farther. But think I will just use my cordless router instead of buy another tool. While the reach would certainly be nice though, not a deal breaker on my stubby ryobi router.
How much free time do people have to get into a heated argument about a die grinder? Lol. Looks like a handy tool btw.
