- oztooltalk take a look at the latest brushless angle grinders from Dewalt, the DCG405 and DCG406.
Super compact and powerful, we put it through it's paces to see what it's made of.
I had a lot of old pipes and rebar to cut up and from what I read czcams.com/users/postUgkxPDBfLu68o58Aw85O_J-zIFfjJARBhp-3 this would be the tool for the job. Since I had never used one, I watched a couple of youtube videos and I'm so glad I did. Some really good safety tips, which I followed, and this tool did a splendid job. One good thing to know is the weight of the tool puts just about the right amount of pressure on the metal I was cutting, so I didn't have to use a lot of pressure, which is more likely to jam the tool. It made fast work of my job.
I agree with the additional spot for the handle. If you are cutting something vertically, EG a cutting off a pole at ground level or something then the normal position is fine. But say cutting horizontal you really need that one on the back inline with the center of the disk
And for me, switch all the way. Im often having to cut stuff off at odd angles and in less than optimal work conditions so having to hold the paddle for me would be a pain. My main grinder is still the original Makita DGA504 (i think) anyway
What an awesome and detailed review, thanks for taking the time to put this together. I just ordered the 20 V version, # DCG405B and I think I'll rather happy with its capabilities after watching this review.
Almost all of my power & battery tools spanning some 35 years are Makita. Back when I first purchased Makita corded tools, they were rightly rated industrial tools, whereas given the pricing wars these days, I’d only rate them as trade tools if that makes sense. Because I’m so invested in Makita 18v tools & batteries, I don’t really consider anything else. However I had the chance to use an older Dewalt 18v brushed paddle grinder running at 7000rpm. I wasn’t expecting much tbh, especially as I already own a Makita 18v 125mm grinder, but jeeze, I was astonished the power of that thing. I deliberately put weight on the grinder while cutting angle iron, just to see how much it would take to stall it. I have to say, it took a fair bit of force to stall it. It made my Makita grinder look pants. My old brushed Makita grinder has half the power and worse still, if you push the grinder, a red light flashes and shuts the grinder off. I’ve not tried Makita’s latest brushless grinder, but I’m confident it wouldn’t compare with Dewalt’s DCG 405N. I’m so impressed with the Dewalt 18v grinder that I’m seriously considering buying one. I never thought I’d buy anything other than Makita. I’m really happy with my other Makita tools, with the exception of their poxey underpowered grinder.
Bit the bullet and went over the dark side and bought the latest Dewalt grinder, which runs at 9000 rpm’s. Totally impressed. Unfortunately I’d not seen your Makita- Dewalt comparison of their latest machines. I don’t want to watch it either because if they’re just about equal, then I’d have bought the Makita, having so many 18v batteries. Still, either way, I’m so impressed with my Dewalt, I don’t regret buying it, plus I managed to get a couple of almost new 4 ah batteries for just a few favours as my pal has gone Bosch, so a small (ish) investment.
we did a cordless grinder comparison not that long ago. The Dewalt and Makita were equal winners. Both are exceptional units, with the Dewalt being a little more powerful. Go check it out :D
You could say I’m a Dewalt fanboy, I have 3 tools now and love them all.
I have 2 :D a Drill and a 1/2" impact driver DCF899NT
Nice to see you appreciate Dewalt tools finally
Joe Framer Lol you speak as if we havnt before !??
You need to watch a few more of our vids mate.
@@OZToolTalk you tied them for #1 with Makita.
This guy just needs an excuse to flex his victim complex. Brand deification like this tends to bring out the worst in people.
I purchased the 406 paddle, reason being you can turn the grinder of with both hands holding. Recently cutting in a confined area after removing the grinder and letting go to turn it off the the whole thing moved enough to catch the outer coating of an electric cable! Momentary eye deviation but enough to scare me just a bit
I own this grinder one of the best ive used.
Would like to have seen more on the paddle as I’ve never seen it before but otherwise thanks great vid 😊
Noted!
been looking into getting a Cordless Grinder for Cutting tile as that is my main use for it, I have an older Dewalt one that switch is broken so i have to keep the switch pushed on and its too costly to fix so Cordles is getting serious consideration
I recently purchased a DCG413 with a paddle . Do you know what other differences there are ? J K
Scored one of these in a kit with a 5ah batt and charger for $199 aud
Can you use flat discs on these or do you need depressed center?
Good review thankyou gents
Our pleasure!
also do flathead version DCG405FN
Just got the dcg405n...two 5 amp bats..charger..stacking box...bit dissapointed it didnt come with any discs at all !!....good quality though !
nice one. I think you'll manage to pickup a couple of $1.5 discs ;)
What type of guard did you used in the cordless?
Some sites in NZ wont allow use of the switch tool for safety reasons. Paddle only.
pretty annoying ;)
Is this an up dated brushless then?
What is the power compared to Bosch and Makita 18v grinders?
Joachim Osmundsen Jump into our latest massive grinder comparison here on CZcams and watch it 👍🏼👍🏼.
It will have ALL the answers you want.
yeaaaah, yep.
Where are they made?
hi guys, just wanna ask about the runtime per 1 single charge of battery, eg 5Ah using with our dewwalt brushless ??? so how long does it takes till the battery run out ????
It's hard to say, it varies so much depending on what you try to do with it. To give you an idea though, watch our grinder comparison, which includes a runtime test. [Dwain]
im a little surprised you didnt mention the 54v grinder, do you prefer the 18v one over the 54v? thanks,
I'm surprised too. I prefer the 18V one for light-gauge stuff, and the FV for bigger stuff ;) They're both awesome.
Roguey We did review the 54V previously though, you will find it in our Dewalt playlist.
I just scored a dcd996 drill, dcf887 impact driver, the 406 grinder, a 6AH fvolt bat, and charger for 549 NZD(like 450 aud)
Nice!!
Same. I'm in NZ too. Everyone is buying that kit, it's a great deal. I already had an 887, but I decided to keep the other one because sometimes 2 impacts speeds things up, not having to change bits constantly. I'm really impressed with this grinder though. And the drill is a beast too.
awsome, im from nz also. What shop ?
@@eliazografos2561 it was all the shops, a Dewalt promotion. Varied a little. It's over now though I think.
Does it reverse?
Feel opposed to having the paddle trigger on a grinder. Works beautifully on the multi tool but grinders are really dangerous and having a trigger like that I feel would result in accidental engagement. Let me know if my concerns are valid.
the paddle is supposed to be a safety feature. if it leaves your hands for any reason, or you let it go because of an accident, the power turns off immediately.
Hi guys, need a fast response on this if possible,
Can this run with a DCB181?
I don't know how the battery compatiability works on the xr series...
yes, every 18V tool and battery are compatible (excluding the older style of stem pack 18v batteries)
Thank you.
Would you recommend the 18V or the 54V?
[Dwain] depends what you are cutting! I find the 18V enough for most things.
I'm about to start buying good tools and I want to stick to the same brand!I am pushing towards makita but would you if going to spend a few grand on tools go down that road?Thanks great channel
I’d get makita to start with. If you like a particular tool from another brand, you can just a an adapter to use the makita batteries.
Ive been an Electrician (incl apprenticeship) for 5 years. Ive been asking a lot of questions of co-workers about all the different varieties of brushless Batt operated power tools. Im finally about to invest in some quality (Have been using AEG which has been ok) - and Im going with De Walt, for what its worth. Almost took the Milwaukee brand, but they dont do a good quality power cable stapler like De Walt do so that ended up being the tipping point. Otherwise, either of those brands seem to be the preferred overall. When I first started, everyone said Makita was the bomb, but over the years - most people opt for the former in my experience.
All my tools are dewalt and i work with 5 people who have all makita sets they're constantly complaining about they're tools dewalt are absolutely spot on 👌🏽
Hi mate, new to this channel, was wondering if you could say what your thoughts would be to the best battery operated angle grinder on the market today is?
Hi Ben, in terms of high power units, it's hard to go past the XGT and Flexvolt units. If you don't need the most powerful units on the market, there are many excellent. units around, including 18v units from Bosch, DeWalt, Makita, Metabo, Hilti and AEG. have you watched our grinder comparison?
Love the review guys, but didn't really feel like a head to head comparison. I'm not sure if that's what you were going for, but I've not really come away knowing the key differences, maybe I missed something, but other then that, cracking video.
It definitely wasn't a head to head, because they are just two variations of the same tool.
And thanks!
@@OZToolTalk maybe head to head wasnt the right choice of words, but key differences and what stands out between the two, why you'd wanna buy one over the other sort of thing, and youre welcome!
Well the only difference is the switch, which I think we covered in quite a lot of detail 👍
Do these have overheating issues like their impact drivers? Asking anyone in the comments if they experience with these
in my experience, most impact drivers (not just dewalt) can suffer from overheating when used hard for a long time (e.g. battening down roofing timber). I've not had a similar issue with the grinder, no.
@@OZToolTalk that’s good to hear as I just bought one . Thanks
Hi Guys
Just watch your video on the DeWalt DCG405 20v brushless grinder. I'm across the pond but we don't have the grinder with the switch on the side. I just don't understand that one. I like that style then the paddle. I just wanted to know if there is any difference in the batteries set up or charger. I would like to get the one with the switch but can't find one here. Maybe i just have to buy one from you..Lol
Michael Carrion That’s weird you don’t get it. I don’t understand how some countries miss out on options.
batteries the same. just have to check voltage and plug type for chargers
@@OZToolTalk thank you for that info.
It's likely the switch type will disappear soon. It's considered a hazard. They are convenient, sure, but we have all had a switched grinder fcuk off on us. Triggers and paddle switches are where it's going. Same as the triggers on circ saws. You won't find any new ones on the market that don't have that thing on the side you have to push with your thumb to unlock the trigger.
@@Patrick-857
That's weird because in the U.S. Makita and now Milwaukee has the switch model on their grinder but it's on the top and not on the side.
Hey mate what is the power output of the 405 incomparable to a corded grinder
I would say that it isn't quite as powerful as an entry level (~700W) grinder. But it does a great job of almost all cutting tasks.
@@OZToolTalk thank you for that much appreciated 👍
how does it compare to the Cheaper unit DCG412 Brushed
substantial improvement.
@@OZToolTalk Kool Mate - i ended up Getting the DCG412 on Sale $99.99 CAD : Prefered the Smaller Grip Size and Lower RPM : DeWalt Upgraded the DCG412 Guard to Ratchet Style like the DCG413 :small Detents Counterclockwise Adjust .
Would 3ah battery be enough to power one of these??
It won't be AS powerful as a 5Ah, but yes a 3Ah has enough power. A 'compact' 3Ah might struggle...
@@OZToolTalk ok it's just that I have 2 battery's with my drill so was thinking of buying a bare grinder unit
Milwaukee fsagv125 or this dewalt??
Thanks
Both are great 👍
@@OZToolTalk thank you:) which is stronger, which is more ergonomic?
Try getting one in the UK at the moment.....impossible!
really? they're so easy to get in Australia, especially the paddle version.
@@OZToolTalk yea there like rocking horse shit over here at the moment. I’ve finally managed to get one though 👍
what about this model with a 24 v battery? Cant tell if it is genuine Dewalt or chinesium. the kit came with 2 24 v batteries and a case ? was i scammed? should i throw it away ? , can someone fill me in?? thanks
yep 24V is not right, definitely not genuine.
Ozzie, Ozzie, Ozzie..
oi, oi, oi
could be batter and clear on point may make the bullet point
The switch must be put in the midle, not in the left side. Is ergonomically stupid, because for cutting the sparks and dust go to the worker, like in clip images. If somebody want to change the guard, the switch will be on the ground side, almost imposible to use.
You can rotate the head to any side i believe
@@rynomadman1 yes you can, and doesnt require a screw driver to adjust, it simply rotates and locks into place
Do i have to pit only 125 mm??? Can i use 115 mm in it?
umm it depends whether the arbor size is the same. if so, then it would be no problem, but I suspect not.
Flexvolt do give more power, in every tool, another review channel did lots of tests, every tool performed better and better froma 2.0ah 4.0ah 5.0ah and flexvolt did the best, higher blade speeds, and more torque
The voltage sag will be lower with flexvolt batteries. There are 3 cells in parallel in a 6-12Ah flexvolt battery. Compare that to a 2Ah with just 1...
On a high current device, you should see noticeable improvements in performance with larger Ah packs.
@@chris746568462 It's not just the higher cell count. They are 21700 cells not 18650s. Much bigger cells, with much higher current capacity. The performance difference with a flexvolt battery vs a normal 18v battery on my 18v circ saw in particular is very noticeable.
@@Patrick-857
Yea, that will certainly help too. Though i think dewalt use Sanyo NCR20700A.
@@chris746568462 Maybe for the 6AH ones. Pretty sure the 9 and 12 have 21700s.
@@Patrick-857 Larger cells may be capable of putting out more current, but I doubt they will unless the tool intelligently demands it somehow. A tool won't spin any faster at no load just because of 21700's. Possibly a little because of less voltage sag, yes, but not because the cells have higher current capacity (the 18650's are not worked to maximum current draw anyway). The tool has a certain resistance (at each setting) and it's voltage that overcomes that resistance. If you want more current flow, you need more voltage or less resistance. Simply using more or bigger cells at the same voltage has only a small effect and that's due to voltage sag. I agree with chris, the difference you notice is due to a greater number of cells in the flexvolt leading to less voltage sag under load (the load is shared amongst more cells).
Why is it 18v?
Here is the U.S. it's 20v
ToolmanHenderson No they didn’t mate, America calls it 20v and Australia and many other countries are 18v
@@OZToolTalk So same tool just different sticker?
ToolmanHenderson Yes, 20v is the max output I believe but it’s a little cheeky calling it 20v
Dwain has more of an idea of the specifics.
We are also planning on a FULL battery overview for CZcams soon and I dare say this topic will be covered. (Mike)
Marketing thats why
I bought the 20v job site fan from the US, shipped it to Oz, and it runs perfectly on my 18v batteries👍
I am confused with models as u are not mentioning it in video and god knows on which model you are talking on
sorry, look in the description
Take the battrey off please !
It doesn't work like that :P
I would not waste my money on over priced tools when the bauer which I've had for everything I'm not talking about the first gen but the second gen grinder is fantastic my boss has a ridged and I out last and cut faster then his and I never had a big down or cut off unless the battery was running low and I put some good pressure on it

Very good tool but this well shot video is sooo unprofessional. Why? Because lack of gloves, proper working clothes etc? Safety first!
