Dewalt Atomic Cordless Grinders are Available and on Sale

Dewalt Atomic Cordless Grinders Now Available Update

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.

Here’s what I found so far, along with the prices I’m seeing.

Dewalt DCG400 4″ Angle Grinder Tool-Only – $299 at Acme Tools
Dewalt DCG400 4″ Angle Grinder Kit with 2 PowerStack Batteries – $599 at Acme Tools

Dewalt DCG402 4-1/2″ Angle Grinder Tool-Only – $229 at Acme Tools

Dewalt DCG420 Die Grinder Tool-Only – $249 at Acme Tools
Dewalt DCG420 Die Grinder Kit with 2 PowerStack Batteries – $399 at Acme Tools
Dewalt DCG420 Die Grinder Kit with 1 Small PowerStack Battery – $399 at Acme Tools

The die grinder kits warrant some explaining – one comes with 2x 3.5Ah batteries, and the other comes with 1x oil-resistant 1.7Ah battery.

Dewalt DCG422 Right Angle Die Grinder Tool-Only – $249 at Tool Nut

    Bare tool prices are a bit overreaching. So many other options at lower prices unless you’re just stuck in yellow.

      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.

      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.
