ฝัง
- เผยแพร่เมื่อ 28 มิ.ย. 2022
- The week we are comparing different size grinders to see how much of a difference size and power make, to see what is the best angle grinder.
The test includes the following DeWalt grinders:
D28402 - 4.5" 120v Corded Angle Grinder
DCG413 - 20v 4.5" Brushless Cordless Angle Grinder - amzn.to/3XVRR1C
DCG416 - 20v or 60v Flexvolt Advantage 4.5" to 5" Brushless Cordless Angle Grinder - amzn.to/3XMnlrb
DCG414 - 60v Flexvolt Brushless 4.5" to 6" Cordless Angle Grinder
DWE4597 - 7" 120v Corded Angle Grinder - amzn.to/3H7je38

What about the DCG 418 why wasn’t that included? DeWalt claims a 30% improvement on the DCG 414.
I'd love to test it but don't have one, I'd be really interested in seeing how it does over the DCG414 as well.
Very cool video and idea. Very informative. I prefer the large style grinder for doing large surfaces such as a body panel while I'd use the smaller version for some small metal work. Guess I have to own them all :)
Thanks!
I actually find I use the small 20v cordless the most out of any of these...just easy to control/blend. Then probably the 60v cordless next, it (clearly) moves as much/more metal as a corded 4.5", for removing more material.
But if I'm doing a pile of grinding work, the 7" is just a beast...I usually run it with a coarser wheel too, so it eats even faster than this video shows.
@@SomeGuysGarage Yea I usually run the 7” with a flat sanding wheel or even throw a buffing wheel on it. Great tools
Excellent test. I still got the DCG416VS, since it is lighter with the batteries, has variable speed, and is a bit more powerful than the 413 or other older 20v models. I thought about getting the flexvolt and it was about the same price even. However it seemed like the 416 is powerful enough and it is compatible with my current collection of 20v PowerStack DeWalt batteries. I also like to keep my battery power tools light, hence I stay with 20v and the small 1.7ah PowerStack batteries mostly. I do have a couple 6ah bats for the bigger tasks (like using my rotary hammer drill).
I'd really love to try out that new variable speed one! It came out just after I got my DCG416 but I've been itching for a variable speed grinder for a while, and I think would make the case for the 416 a lot stronger as it's a unique feature.
How's the runtime with the 1.7ah powerstacks? I usually only need one or two 5ah for a day of fab work, but I'd imagine the powerstack would get eaten up several times?
What a great way to compare grinders' ability to do work!
I mean that's what we're using em' for right? Might as well test/compare them that way!
Thanks for this video, very informative! I'm considering corded vs cordless and leaning towards a corded grinder because I hear they drain batteries quite quickly compared to other power tools. Any comments on that?
Depends on what you are doing with it....the cordless ones are awesome for quick clean ups before/after welds. A single 5ah battery will usually give me a full day in the garage welding before needing a charge (15-20 minutes actual grinding time).
If your primary cutting tool is also going to be a grinder or you're doing lots of grinding (say prepping for paint on dirty metal) then corded is the way to go unless you have lots of batteries.
You'll eventually end up with both though, I keep different wheels on the grinders (though love flap discs for a lot of stuff), so it's easy to just grab the right grinder and go.
Hope that helps and/or let me know if you need anything else :)
@@SomeGuysGarage Hey, thanks for the detailed reply. My use case is actually carving bark of wood, I'm primarily woodworking at the moment and while I can clean most of the bulk with a chisel + hammer, a decent amount is left over sometimes depending on the individual piece.
I opted for the cordless angle grinder (Dewalt DCG416B), and paired with a 40 grit sandpaper flap wheel, it works great for my application.
It's always a tough decision to make, but yeah the battery dies extremely fast compared to other tools used. Luckily I'm only sanding for a couple minutes tops. In my case, the convenience of not having a cord was worth it.
I probably see myself getting a corded one in the future for bigger tasks. Thanks again!
@@DefaultUserGaming you're welcome! You can always go to a bigger battery on the 416 to get more runtime and a bit more beans out of it. Corded will come in handy if you need to go for an hour or something, but I agree the cordless is just so convenient!
Make sure you blow out the grinder now and then, the dust build up with wood will kill them eventually, just a short blast of compressed air into the sides does the trick.
Enjoy the new toy :)
My favorite is the DWE43116 rat tail (13 amp), but I definitely like the 60v as well. I've got that same Miller welding table - I like mine alot! Nice test - thanks!
No, thank you!
The 60v is quite the grinder for cordless. Their 60v stuff really is as good as corded (I have the circular saw and sawzall too).
The 30FX is great too, folds up into no space which in a small garage is awesome, just a little pricey for what it is.
Both the power detect and flexVolt advantage models are really meant to be run with 21700 cell batteries. Compact 4AH, 6AH, 8AH (sweet spot), 10AH, or flexvolts
Interesting, I have one of the new 3ah 21700 cell batteries...next time I'm in the garage I will see how it does.
I wouldn't mind trying the new powerstack battery, or really any of the new lineup. I only have the 2ah 20v, 5ah 20v, 6ah 60v, and the one new 3ah 20v. I had a couple 4ah 20v's that came with my original kit years ago but I gave those to a family member.
@@SomeGuysGarage, the 3AH and 4AH compacts are both 21700’s but being I row (1P) they don’t deliver the same power as a 2P pack like the 6 or 8. The 4ah compact will out perform the 5ah standard battery but won’t shake worlds. The flex 9ah or the 20v 6ah, 8AH, 10AH will all really wake up the tool and you’ll have more runtime over the 60V grinders. That said, if pure power is the game then the 418 and 440 are where it’s at. Long jobs corded is still king. I do like that dewalt is offering their brushless motors and advanced safety features on their new corded line up
@@SomeGuysGarage, power stack has great power but not a lot of runtime. I mainly use them on my impacts to maximize power while being light weight. And in an impact it has respectable runtime for me. In my drills it doesn’t have the runtime, but I’m usually using my drills for self feed bits and hole saws. Not small holes with regular drill bits. Exception to that is pocket holes. My M-12 fuel hammer drill (gen 2) is pretty gutless in all modes so I just leave it set up for pocket holes. My 998 is my go to and my 791 has enough power to work in tighter areas. I do want the flexVolt in-line quick change stud and joist drill. And might upgrade to the new Dewalt compact drill (DCD 800?)
@@nsatoday that's some really good rundown on these things...the 418/440 look awesome but not sure I need another grinder lol especially since the corded 7" I have is just an absolute monster.
I will keep an eye out for some of those new battery packs for a good price, every now and then amazon or home depot do a good deal.
Very good comparison!
I personally have the DCG416. I was aware from that the start that the 20V motor inside is going to be slower than the 60V flexvolt motor, but where the DCG416 really shines is the flexibility. The flexvolt batteries are much more expensive than the 20V batteries, so its a fair compromise between the regular 20V angle grinders, and the 60V flexvolt angle grinders.
I think in the case where you already have 60v batteries and no grinder yet, the flexvolt advantage option is a good choice...but if not, just get the 60v grinder or the 20v grinder.
@@SomeGuysGarage i think your missing a certain perspective, for me for example the just 60v one is a worse shape, to big and weird shape for how i use them but mainly with the FV advantage i can have just 1 flexvolt battery for when i need all the power and i can have other battery's for smaller jobs, i dont need to have only FV, for a drill and driver i dont really need all that battery and i dont really wanna spend the money on multiple FV battery's , i do a lot of car stuff and for sheet metal or cutting random stuff i dont need the 60v power but if im fabing up something out of thicker metal i would use the FV battery. i dont usually need a powerfull grinder but this way i have enough it can replace my corded
@@charlieward7606 I guess for flexibility in use it makes sense if you only have one grinder. The thing is, flexvolt batteries just cost soooo much, I'd suspect 99% of the use of the flexvolt advantage grinder will be on 20v...at which point, why pay the premium for marginal extra performance? If you can get it at the same price as the straight 20v, then sure.
@@SomeGuysGarage yeah all my tools have steadily died, i have a cord drill left but i really need a grinder right now, from what ive seen the FV advantage is pretty much on par with a corded grinder, so instead of buying the regular one and maybe still needing a corded grinder just bite the bullet and spend both on one. and then il have a dewalt charger and bat good enough for anything i may want in future, and for lighter jobs i can get some regular batteries which i can use with my future drill and driver. maybe im putting to much thought into the extra power but all the tests ive seen have shown a noticeable difference, i can even hear it in the videos
@@charlieward7606 I would just caution that battery runtime, regardless of battery type or AH will never live up to cordless. These are 15-20 minute runtime tools per charge, at best. For quick cleanups or occasional cuts they are SUPER convenient, I can go a day doing cleanup for my fab work in the garage on a single 5ah...but as soon as I try to do anything more, the corded has to come out.
As for power, the FV Advantage on 60v definitely is a step up from a straight 20v grinder...but it's nothing like the full 60v cordless...and if you always run on 20v, it's not worth it. So ultimately, if you have flexvolt batteries and only want one grinder that can be comfortable and have some beans, it makes sense...otherwise, go bigger or save money :)
Side note, there's also a reason I have so many of these grinders...I usually keep a variety of wheels on them and each for a different purpose. Multiple grinders is the way to go for anyone doing a lot of work with them.
Appreciate those who liked/subscribed :) we're almost to 500!
What style trigger do you like the most? Which one is most comfortable for hours of grinding ?
I'm good with the lockout paddles, doesn't even cross the mind...I don't like slide switches or triggers as much (like the 7" in this).
@@SomeGuysGarage is there a couple paddles from dewalt , can you lock the paddles to the on position?
@@TrailBoundconone of the ones I have from Dewalt in this video are lock on...I do have another brand grinder that is a lock on slide switch and I really don't like it.
I have the corded baby grinder which I see is not part of these Test, however I would like to know how strong is the DWE4957? 🤔 Is there a need for it if I have the baby grinder for DIY?
Absolutely not, the only reason I have a DWE4957 is because I got it for an extremely low price...I have used it for concrete floor grinding with a diamond wheel and I will use it for grinding if I need serious material removal, but I could have done everything with a standard 4.5" grinder too.
@@SomeGuysGarage thanks man. Is it reliable and strong though? 🤔
@@lwandilebaliti2595hasn't let me down yet and it's ridiculously strong, you can't bog this one down without it getting scary lol
@@SomeGuysGarage thanks man. Really appreciate it. Maybe when it gets cheap I will probably buy it. 🤣 Cuz they are ridiculously expensive here in South Africa but I have a place where they usually sell them with very low prices.
@@lwandilebaliti2595they have a few 7" and 9" models to choose from, all would be a fair bit more powerful than the 4.5" grinders.
The other one I'd love to try is the DCG418 (new version of the DCG414 I have), the flexvolt grinders have a lot of guts!
are they all M14 Spindle Thread? thanks
They're standard 5/8"-11 UNC on mine...but this might change in different markets.
What is one of test dissapointing? And why?
The flexvolt advantage grinder was disappointing...it only really performs better with expensive flexvolt batteries, but at that point you might as well just buy the 60v grinder for the same price which has WAY more performance.
High speeds, are quick, faster Speeds
Yup, not just rpm but sfm.
Fast , easy , and cost save , 4 inches....wins wins .
Nope :)
Different kind of tools , use for tiles, steel , aluminum 's, pipe 's, wall,and wooden ...may be small 4 inches, 3 inches tools ,do had hign speeding wheels.... bigger wheels, speeds, will not higher than ......8000 or lower than ...rpm.!
Yes, but the larger grinders can still have higher sfm and often more power so you can put more pressure on them and move more material without bogging down.
Smaller grinders are useful though for detail/precision work.
Once spent money 's on 4 inches of powertools ....done , works faster.and cost save , in wheels ....disc
Disc cost differences are negligible when buying in bulk.
What a waste of my time
Sorry to hear that. Is there something I could have done better to provide you the information you were looking for?
@@SomeGuysGarage More cut comparisons, metal, concrete, sanding, etc. Maybe talk about kickback and overall control of each size. I know the 7" can have some strong kickbacks if you grind in the direction of the wheel. I'd be curious what it's like if holding in the air cutting rather than on the ground to grind down a floor and what a 4.5" kickback is like if it has any at all.
@@rickybobby7276 I can definitely do comparison with other wheels on other materials.
The kickback thing would be a bit dangerous to test, but I can see if I can come up with something reasonable for that too.
Thanks for the suggestions :)
