I've had one of these angle grinders for about three years and it will cut almost anything, with the right blade. I even managed a freehand circular hole for a fan in the middle of a porcelain wall tile! Cordless makes it very useable and the brake is excellent. This together with the many other XR tools I have make many jobs easier. It is easy to take their convenience for granted. However, if I die, please don't let my wife sell them for the price I told her I bought them for!
I have many categories of tools, hobby items and other things that I have smuggled in undercover. When I get question my usual response is "Yes love I'd had it for years!". I then ask about the latest shoebox size package that was delivered for her.
Just as a general and my 2cents worth of a comment: (having owned the same unit and “upgrading” to one model up "DCG406N-XJ” for both ease of use and general and better “Safety” due to that switch mechanism in particular, which is extremely dangerous in my opinion @9:29 being a prime example) -Prop up your work piece,as your back will thank you for it. not to mention have a far better view on what you are doing. -Get a 54v Flexvolt (I know they are expensive,but its worth the investment) battery as the grinder drains batteries extremely quickly -When cutting metal (and large,thick pieces in particular),make use of a “Pull push”/“ Constant Back and forward motion” method,as it reduces the amount of disc material being use (cost effective and time between changing discs over), reduce battery drainage and prolong work time,and puts less stress on the motor (does not get HOT as quickly) overall… Also get into the habit of “blowing out” the “vents” as material dust tend to clog it up and increase internal compenent heat…and is one of the prime culprits for grinder motor failure…
Looks like a nice bit of kit, and its nice to see more videos in the paddock. Uh, do you really need to give the battery a final slap every time you refit it? Once you go cordless, its best to settle on one brand, otherwise you have multiple batteries and chargers. What made you settle on DeWalt?
Prob controversial but I prefer the paddle to the switch. I prefer the safety of knowing if I do need to drop the tool quickly that it will turn off. I also find it more comfortable to turn on and off with gloves on while I work.
DeWalt are actually very good with spare parts if you do lose your locking nut. I got replacements for broken bits on my table saw within a few days. I did go through the retailer though, FFX, and their customer service is excellent. Your mileage may vary.
I find that you can get more battery life and cut off wheel life if you are gradually "scoring" away at the steel from the top surface downwards through the 'thickness' of the bar rather than cutting through the full width of it like you were. You have the cut off wheel both above and below the surface of that metal bar which requires a lot more power and wears the disc faster. Not sure if I explained that well
Just here to say that both your affiliate links you've labelled as 'UK links', whereas one is actually a US link... :) Otherwise, great vid, .I'm always wary about using cordless tools too infrequently and the battery becoming too discharged and failing through lack of use... :(
I have used de Walt cordless drills for years and they have never let me down . What has not been as reliable are the non branded 18 v Lilon batteries that even brand new just don’t hold a charge like the originals
I love my cordless dewalt kit and would never go back to wired kit.The T stack cases are superb for storing and stacking your tools in.Some people like makita but there cases are so inferior to dewalt.A grinder and a multitool are bits of kit i couldnt not do away with.I always pick up 1 new battery everytime its have a sale.
Save yourself some money by the 115 mm model as it fits the 125 discs, probably a slight engineering fault that would upset the marketing department as the two models have exactly the same specs. Also use 6ah batteries as you will get increase in power for heavier workloads. I have two DeWalt cordless grinders, the Flexivolt 125 and the 18 V 115. Use the 18 V because it is lighter more convenient most of the time but the Flexivolt has considerably more power. I use the same 125mm cut-off discs and grinding discs for both models.
Use mine when I'm working on roofs, taking off TV aerials etc useful but eats batteries for dinner so take spares up with you, saves climbing up and down all the time. Also attache a lanyard so you don't drop it.
I always chuckle at the amount of misinformed and lack of knowledge comments on tool review videos,esp from so called "tradesmen".Its actually quite disturbing.
Bought myself a cordless Bosch angle grinder a couple of years ago cos erm............reasons. Not used it much but the times i have used it have saved me a ton of time and effort. Better to have and not need than to need and not have.
Really like my cordless grinders (3 Makita ones, 18v 125mm, 40v 125mm and 2x18v 230mm), however I had a lot of grinding to do over a couple of days recently so bought a corded one as like you say, they chew the juice.
I bought one of these over a year ago, and it's priceless. I bought the Dewalt as I had the batteries. But, it doesn't have to be Dewalt, just any cordless grinder makes a huge difference. I still use a corded grinder for stone & concrete cutting, but for everything else, this is a must have DIY tool. The cordless type is so handy for metal and plastic pipe, rusted screws & bolts, and a ton of other jobs. Never used it on wood, as I have proper power saws for those jobs. They do tend to get through a 2Ah battery fairly quickly (10-15 mins), but it's a good reminder not to over-use it. As I mentioned, I have other angle grinders. One of the features I love about the Dewalt is the Allen key hole for replacing discs. My other grinders require a specific 2-prong tool for changing discs, which is annoying when you forgot where you put it.
I have purchased a number of the 18 v li lon Erbuer cordless tools and have been very impressed indeed. Although I use them in both a professional and DIY capacity they are not being operated every day , all day so totally appropriate for the price point. They are well built, comfortable to handle and the new fast chargers are fan cooled to dissipate the heat generated. I don’t think you can beat this range that after all has the clout of the Kingfisher Group behind it . Anyone with comments ?
Imagine if the switch goes bad on this grinder. You cannot just buy another switch and replace bad on, you have to buy complete guts of grinder. A major repair issue.
This is junk with 18 volt. The grinder only works for less than 5 minutes. Battery is too weak. This guy does work with these tools. I have all Dewalt tools. this is very poor.
Thanks Stuart, this video confirmed what I thought about the Dewalt cordless angle grinder. I’ve got the Dewalt battery platform as well, but hadn’t bought the angle grinder as my Hitachi corded one is working fine and I only use it occasionally. When it does die I will buy the Dewalt cordless, good to see that it has the power you need. I recently bought the Dewalt cordless planer and have been very impressed by the power and quality of the cuts it produces. Another good toy !
Disks should only ever be tightened up by hand as the spindle rotation will tighten the nut when you’re using it. The tool is there to remove disks if it ever grabs as it will tighten the nut harder than you can do with your hands.
When I saw the video pop up the part I was interested in your take on run time. To fulfil my grinder fixation I had looked at this unit but I have invested in a flex volt battery for my Dewalt tools. So I could go with the same unit as you with 18v or go for the 54v model. You would, certainly get more run time from a flex battery at an equivalent 12a/h on your unit Cheers Stuart 👍🏻
Love the shows very thorough and knowledgeable you are Sir. It'll be interesting to see how the new wizzy disc connection and guard stands up to a decent amount of stone and or slab cutting. I wonder if the new corded version has a similar setup. That said you cant whack dewalt tools a first class company!!
I nearly asked on the kitchen step stool video if you had been getting some new DeWalt tools - well now I know that you have at least one new tool. I've been looking at the cordless grinder for a while now. I have not quite justified it to myself as I very rarely need a grinder but as soon as I do your video has helped me make the decision on which one to get. Thanks.
I have the same one. I agree with your comments a good balance of not being tethered by a power cord and battery life. I run mine on 54v flex volt battery. These are heavier but give the extended run time.
I bought one for use with a flap disc. What a waste of time and money. I started off with 2 4ah and 2 5ah batteries and 2 chargers. The idea was as soon as a bettery goes flat to put it on charge and carry on with next battery. By the time I had discharged all the batteries none had fully recharged. To say it is power hungry is an understatement. I'll stick to my corded grinder in future. Ps does anyone want to buy a Dewalt 18v grinder?
OK, I'm convinced - I’m ordering one of these cordless DeWalt angle grinders. By the way, I see from LinkedIn you started your BEng in 1987. That is when I completed mine. And I thought you must be older than me...
Just got one - agree is excellent and it cut up come steel bar perfectly and quickly - any comment though on the DeWalt instructions that mention a different guard for sanding surfaces? ( it comes fitted with a 'type 1 cover') - I couldn't follow what the 'type 27 cover' is needed for
What happened to your nose Stuart? Was the missus not happy with your spending on more tools ? 😂🤣 I quite like Dewalt, I have many of their tools but it’s odd that they manufacture a tool with a locked on switch which is illegal in America as they are an American company. Another great video thanks Stuart 👍
Buy a 3amp 54volt Flexi battery, that'll give Yuh 9amp at 18volt. That'll last a bit more than your 4 you were using. Should have strimmed. round the greenhouse and made life a bit easier for yourself
For very little more, I purchased the DeWalt 405FN. Essentially the same, except has a less blunt front ‘flat head’ design, that will reach into tighter spots. Get 5 Ahr batts tho’ cos they devour power.
11:04 - Just a nerdy correction: there is still quite a bit of charge left in it. Lithium batteries can't be discharged below a certain voltage or they get damaged, so the tool (or the battery's own protection circuit) is preventing further discharge, but if there was "absolutely no charge left in it", you wouldn't be able to use it again.
My good friend, you are smart and knows how it works. You saw the tool drop directly under your leg but you looked 3-4ft above you and found it LOL. That was scary but thank goodness you found it. Love the music! Edited opps... I ended up getting the flex volt, I'm not really big on marketing fluff but the flex volt is actually flexing the volts. The batteries costs like heck but thank you amazon knock offs lol. It lasts way longer. The important thing when you first get batteries is you have to discharge them first before giving it a fully no bothered charge. My 5ah lasts forever! 30 cuts though, that's a kitchen tile job or a 1 day work day with bathroom time
At about £165 for the bare unit its just about justifiable cost wise for an occasional use tool and I have seen a deal for £184 including a battery which is a good buy, I will buy one when my old corded one drops dead...
Hi Stuart, I don't suppose you're in the market for a leaf blower, or have any intention of doing a video on one. I'm debating with the wife whether I really need one or not, and currently I'm losing. Seems like a handy tool for the DIY'er for more than just blowing leaves
Bought mine from ITS a while ago during a sale, I wonder who put me on to them! Only wished I'd bought one sooner, no more sitting there with the metal hacksaw for me, thanks very much.
I have one of these and they are really good. Do you have any 5ah dewalt batteries? They make any tools work better, not last longer, the tool spins faster, same as the 6ah 12v Bosch set the tools fun faster

Thanks Stuart, looks like a good piece of kit ! I bought a cheap own brand cordless grinder a couple of years ago ( it was on offer and I already had the batteries) and although it only cuts 2 or 3 slabs before getting hot and giving up, it does mean I can concentrate more on not cutting my toes off than where the blasted cable is ! Mine is also of the "rat-tail " design popular in the USA with a paddle trigger which is more natural to my thinking. Be careful on that roof, will you be using crawl boards ?
Hi Stuart, Great review. I, like you, have moved towards cordless power tools. They do represent freedom from tangled cords for the DIY’er. Many thanks. Cheers ✌️👍
Nice video Stuart - and nice tool! I bought my first angle-grinder last summer - a corded one, and a terrifying beast! Shattered a cutting disc the second time I used it and I've avoided using it ever since. I've wondered whether a cordless one might be a wee bit less aggressive and let me get used to them, or should I just grit my teeth and man-up to my corded one...? LOL
My honest opinion (And no offence given), is that you have used a cheap grinding disc from a cheap manufacturere ; the wrong Rpm disc (They are all rated to operate at a certain speed,and anything above that speed will result in shattering), or a damaged disc that has had a crack in already… (The amount of guys Ive seen on jobs, that pulls out a used grinding/cutting disc that has been thrown into the toolbox with tools ontop..blows my mind,as it is accidents waiting for happen) The battery version that Stuart is useing does run “slower” than most corded ones…
@@mariusenslin thanks, Marius, and no offence taken lol. Yes, that's more than possible - and coupled with my inexperience, a recipe for disaster. Should I practice with thicker discs, cleaning rust off steel etc, to give myself a better feel for how the grinder operates? Thanks!
@@MarkMichalowski definitely a good and overal practise and approach..👍🏻 The right PPE (Safety Glasses/goggles at least or even better a full face Visor as Stuart is using, Some “grinding” gloves and hearing protection in my opinion)…. also ensure no lose clothing (Myself have learned a valuable lesson when some dangling hoodie drawstrings got “grabbed” and tangled in the grinder…thankfully the quick stopping brake when the trigger gets released ,kicked in, and the visor took a hit in the process.. ever since then… more care and attention gets given when working with the grinder… Have had a couple of wake up incidents where a wire cup wheel has graced some skin of the hand (nothing serious and fatal though), by my cowboy moves and stubbornness, when not wearing gloves or it being tok much effort to put them on after taking them off…🙄
Just in the market for a grinder for cutting some roof tiles, so a very timely video for me Stuart. Any chance of some more info on types of blades for different materials, maybe as part of your future project which I’m sure you’ll be posting on YT?
I've had one of these for a while, It's got some proper power but it eats batteries like you say, more so than any other DeWalt tool I own. It chews through batteries so fast that they get hot to the touch, so I've taken to swapping batteries mid grind when they are about half empty, just to prolong their life and not overheat them. Great for using up a ladder though or in a field working on my tractor. Dewalt also need to come out with a variable speed cordless grinder as this this thing way to fast to use diamond core driller for drilling into natural stone/marble/granite. Not sure if they have plans for one.
