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

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:

“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 ?♂️
ca
They’ll sell you another one obviously.
Chris I
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. More 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.

You missed one, DCG418 2300W Flexvolt

Dewalt is actually updating Flexvolt tools with the equivalent power detect.

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.
Stuart
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?
ca
How dare you post news about new tools on a tool news site.
Stuart
Honestly, skepticism is good in today’s day and age. It’s the tone that’s frustrating.
Gordon
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.”
DirtyDustyBear
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.
Bob
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>

Newer Flexvolt 9ah batteries and the 12ah (although these are prohibitively expensive) may well work, but older ones don’t.
Big Richard
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.
Kingsley Smith
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.
Big Richard
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.

“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!
David
These numbers are BS so it’s a 75 amp tool?
