It looks like all of the new Dewalt Atomic series 20V Max cordless grinders are now available for purchase.
Some of the new models are described as being in-stock, others are orderable with an ETA of 2-3 weeks from now. Just one, the right angle die grinder, is more difficult to find and listed as “available to backorder”.
While I typically don’t post about the availability of new tools like this, some retailers – namely Acme Tools – has been running coupon offers that can save you quite a bit of money, and there could be other opportunities for Black Friday or throughout the holiday season.

Thank you to MM for the heads-up!
If you missed the discount offer, be sure to check back throughout the season. Here’s a screen capture of what to look for.

Bare tool prices are a bit overreaching. So many other options at lower prices unless you’re just stuck in yellow.
Saulac
These could be a new class of cordless tools, another step closer to completely replacing pneumatic tools. It’s no accident that they shown the tools in a metal shop setting. The compact heads on these tools will allow them to be used in situations not possible with the existing cordless tools.
MM
I’m not happy with the price, but at the same time not really surprised. These are targeted at pros, specifically replacements for air tools. These are something you would buy only if you needed the compact size. A normal full-size grinder would be better for general purpose use, and Dewalt has a few of those which are also a lot more economical. There is a lot of this sort of thing going on, where the target market for a tool tends to set the price more than the mechanical complexity of building it. A good comparison would be Milwaukee’s various random orbit sanders. The M18 5″–a standard all-around tool–is often on sale for under $100. The M12 6″ sanders–the ones targeted to the autobody market as replacements for pneumatics–are $300 bare tool and very rarely go on sale.
I’m interested in all of the 90 degree units, but I have a bunch of grinders already so this is definitely “want” rather than “need” territory for me, so I think I’ll be holding off for a while.

Wow the pricing is outrageous. $299 for a tool only angle grinder is unreasonable

Now I’m torn between this right angle grinder and Bosch’s 12V. Those are just the 2 platforms I’m in.
Will
Why is the 4″ angle grinder 70.00 more than the 4.5″? Anything special about it? It looks exactly the same with slightly larger guard.
Stuart
Unfortunately, I have no idea. I also can’t tell you why the 4″ grinder kit is DOUBLE the price of the tool-only grinder. It’s not just at one retailer – I’m now seeing more prices at HD and elsewhere, and they’re all the same.
Will
These kit prices in general are pretty high, but the 4″ kit includes two 3.5 powerstack. For some reason those are priced to the moon.
Stuart
Home Depot has a 2-pack for $179, which means the charger and regular tool bag is responsible for the remaining $120 difference?
$599 for the kit vs $299 for tool-only seems excessive to me.
Will
It’s probably based on the 299 msrp for the two pack. I agree, the price is excessive. It would take a lot more than 15% off for me to buy any of these and I’ve been hoping and waiting for a right angle die grinder for years.
Will
That two pack from Home Depot is coming up at 212 to my zip. This has to be the highest price per ah of all the dewalt batteries.
MM
They do look the same but I think there might be some internal differences. The DCG400B (4 inch model) is advertised as being 755 maximum watts out and 12,500 no-load rpm. Meanwhile the DCG402B (4.5in) is quoted at 760 mwo and 11,000 rpm. The power is nearly identical and the speed difference is only about 10%, but there is some difference between the two, perhaps in the motor winding or maybe just the programming?
Will
It could also just be slightly different gearing. The dcg418 and dcg440 are identical except for the different gearing and guard. Could be something similar here since the power output decreases while the rpm increases. This wouldn’t explain the large price difference though. That’s a lot of extra money for 1/2″ smaller diameter and a small rpm increase.
MM
Absolutely, different gearing is a possibility too. I wasn’t aware that Dewalt had done that on other models previously. The difference in power is only 0.6%, that could easily be rounding error on some spreadsheet somewhere.
I tried to look for parts diagrams to see if I could find any difference in the gearing but I couldn’t find any diagrams to check. I did find the manual however, and there are some other differences in there. The DCG400 has a 3/8 in arbor while the 402 is 5/8. The gearbox on the 402 has a provision where you can attach an auxiliary handle but the 400 does not. The 400 comes with some kind of reversible flange that allows it to use 5/8 arbor tooling, and there is a special spot where this adapter can be stored on the tool when not in use.

I could see a extension cord, airhose, and a suitable portable air and generator come into play. Unless your in a remote circumstances you still need to recharge them batteries. Stanley knows there’s a unique market and gonna exploit it and the variant names they sell under..now gotta see if a consumer grade Porter Cable or Craftsman would be made
