POWER STACKING - DeWalt DCF921 ATOMIC Impact Wrench Review [5Ah vs. PowerStack]

We put the DeWalt DCF921 ATOMIC Impact Wrench to the test. Not only do we push it to the limit with the 5Ah battery, but we break out the brand new PowerStack battery to see how it compares. The DCF921 claims to have 450 ft-lbs of breakaway torque. You can get this DeWalt ATOMIC DCF921 impact wrench for $199 for the bare tool, and you can also get it bundled with a 5Ah battery for $199 (the same price).

The best video I’ve seen so far with the foot pound torque testing keep up the great work.

[@dungle-mn3sg]

Upgraded from an older 18v kit. kzbin.infoUgkxW1vOBRCMrgTCDEijzpVzDWsgI-Jm2iQv I independently chose the drill and impact tool, before I came across the kit.I like the 3 speed impact gun. It seems more powerful than my older one, and it can be set to be really gentle. The drill is more appropriately sized for my use. I used to have a hammer drill, but I did not like that it was so big and it was not a great hammer drill. I rather have a smaller drill like this, and then get a corded hammer drill for the odd case I need that.

[@vmontalvo5591]

DIY mechanic here… does everything I need. jumping from 2663 M18 (7lb), loving it so far…

[@djsi38t]

I just purchased this impact.What a fantastic tool,it has way more power than the milwaukee stubby thats the same size.Easily the most powerful impact in the compact form factor.If you're thinking about it...do it,its top of the line....period. And yes it will whip off them lug nutz like nothing.The compact size is the most important thing because it will fit into tight spaces,almost as well as a ratchet.

[@andrewk8636]

The torque test Chanel says otherwise. The stubby is still I bit stronger

[@1234theboz5678]

Thank you for the information, I also purchased the DeWalt after trying to decide between the Milwaukee Stubby and DeWalt. After reading your post along with others I had to go with the DeWalt.

[@tacklefatkids]

@@andrewk8636 actually didn't. Both the M18 and M12 stubby did not beat the Dewalt I suggest rewatching the video. The DCF921 is miles ahead of the compact m18 and stubby m12 1/2"

[@richardmejia254]

I have both, this DCF921 & the M12 3/8" Stubby & while TTC shows the DCF921 being more powerful on their dyno, I've seen (on THIS VERY CHANNEL - ShopToolReviews) the 3/8" M12 Stubby consistently break free the same 450 ft lbs as the DCF921 (& on Part 2 vs the Snap-On, the M12 actually broke free 500 ft lbs). That said, both are GREAT choices & I LOVE both, so IMHO, you can't go wrong with either/or.

[@brianf9619]

The PowerStack battery is Awesome , it's great on smaller tools , but not soo good on higher drain tools like a circular saw , But it is only a 1.7ah after all , I think when DeWalt comes out with higher Amp.hour Power Stack batteries they will do a lot better ... Love the Show ...👍

[@andrewk8636]

Yes we need a 15ah in the footprint of a 12ah

[@mike_t_007]

5aH PowerStack had just entered the chat! 😎

[@johnnywong83]

I recently got the DCF923 w/powerstack to replace my DCF902 2ah/5ah. loving the size and weight

[@jonnyskidmarks]

Just bought one off ebay 5 secs ago new in the box for $118 ... I already own a Milwaukee 2854 and 2962. I'm only taking off car lugs nothing too heavy or rusted out. Can't wait to try it out!!

[@scanyoursector5731]

On the 500 Ft-Lbs the powerstack was breaking it loose at 10 sec. Not much movement, but some.

[@wyattvanloon6094]

I bought this to work in a shop, mainly for a light weight lug nut puller. Works good for lugnuts. I've used on other parts of the car, I'm not convinced it puts out 450. Still happy with my purchase. $290 got me that impact, battery, charger and a 3/8 DeWalt atomic ratchet too. Very good deal, even if it doesn't hit max claimed 450.

[@LSBproductions123]

The 12v hit 450 so I’m sure this one did to

[@user-ie6jc5zh7f]

I just bought the DCF921, along with a 1.7ah Powerstack, a 5ah Powerstack and a 6ah Flexvolt. I'd love to see the same test run with the 5ah Powerstack.

[@jetsetjoey]

The PowerStack may pack the same 'punch' of a 5aH battery, BUT I would really like to see the duration/runtime of the PowerStack...

[@Shoptoolreviews]

We will definitely get to that soon. Thanks for watching.

[@tammyshellikoff3482]

Thank you for your hard work

[@beardedtoolreviews7185]

Which one is more compact? The m12 fuel stubby 3/8 with a 6ah battery or the dewalt with a 2ah battery??

[@maxjordan2625]

Got the 921 myself for workin on my ol jeep and damn does she kick ass, almost got a mid torque for lignuts and suspension bolts but very glad I went with this instead cause it can fit in so many more places but doesn't lack that UGGADUGGA

[@scottbionicnerf8727]

Sorry, I thought I'd seen this video and had left comment previously, but I must've missed this one. Great video. I'm 98% sure I'll be moving up to the DeWalt camp soon, due primarily to the evolution in battery tech. Even if it was 'repackaging' tech not currently used by anyone else in the industry. I know DeWalt says it's 'new', but what I'm primarily concerned with is it's minimal size of massive power output. Put that along with the diminutive size of the new atomic line which rivals the compact line and Bam!!! Decision made.

[@aleksanderursus]

Good episode, as always 😁 Sad thing, we won't get the Power Stack nor the 21700 cell 6Ah in Europe, especially Poland. I would buy one right away.

[@christopherperez6126]

That sucks, what about the 9ah flexvolt, i think that one has the 21700

[@aleksanderursus]

@@christopherperez6126 Thank you for the hint 😁

[@johnnywishbone932]

I just bought a 922. I love the tapered anvil. Sockets have play and are held on by detent pin instead of hog ring.

[@leviSyosef]

What is the diffrence between them ?

[@markbrock4427]

Just bought the kit in the UK...DCF 922 (detent pin model) 2 x5ah batteries, charger and t stack case £330....we seem to have the 18v model and not 20v... seems to be good, I have the DCF 899 which is great but a bit too big for most areas around the car.

[@robertfrate9738]

Hi Tim, it’s very powerful for a compact, it pulls lugs right off, excellent for brake work and light suspension work, very powerful for under hood, very compact gets in tight spots that my 894 can’t, excellent demonstration Tim I love it, ty, Bob,

[@ShredworthyDave]

I agree! The 894 has been my workhorse for years everyday on the job. The 921 is perfect for me since I'm always climbing and sometimes need to get into tight spaces

[@juanc5149]

This is not a mid torque it’s a compact. 894 is still a good 40 to 110 ft lbs stronger depending on batteries used.

[@jacksmith2315]

Im wondering how this stacks up against the dcf901. 12v. The 901 is more powerful than it claims

[@yolo_burrito]

I got the DCF921 along with the 3/8 ratchet and a power stack combo for $230 at HD.

[@jamdc2000]

next episode, compare the powerstack to the normal 2Ah bat; runtime and power

[@investigativeresearchspeci6152]

Is this more powerful than the harbor freight brushless half inch impact rated at 555?

[@jamallaidley4718]

Cool Great Video Tim 👌

[@Billysherry1]

What kind of li on wrench are you using to torque bolts

[@ManCaverTools]

I cant wait till Dewalt releases a high ah battery of that, Great video STR

[@Shoptoolreviews]

You and me both! We can't wait to see some different varieties in the PowerStack.

[@jackofalltrades123]

Black and yellow just looks the best

[@acecyxyooj6954]

I am more interested in your Torque gun, what's it call and where can you but one? The one you use to tight the bolt. Thanks

[@EpIkYrIgMeNoS7]

Very nc test I already have the dcf 850 well its completely different tool for what it does compared to impact wrench that's why I want also a wrench and I start to watch videos well this one suits me better for my job I dont change tires I am hvac and rarely I come up aginst big bolts for heavy compresers that need to be opened and this is where 200 nm of torque fail for my tiny beast dcf 850. As for the batteries I have plenty classic 5ah and I got dcf 850 with case and 2 5ah batteries but it was too heavy for me so I decide to check the new power stack I got a 2ah battery to lose some weight which I did in order to lose the weight dewalt I guess remove some plastic from the case as a result the tool if u leave it on the floor fast it don't have good balance it might fell on its own I notice this also in your video it's a small drawback.The huge problem I saw in these batteries I font know about 5 ah but in my 2 ah battery the plastic from the case seems low quality compared to the old ones . I keep my impact driver always in my toolbag one day I saw the front bottom of the battery where you have the switch to remove the battery broken . Dewalt use low quality plastic and too short screws I opened the battery and replaced the old screws with new bigger ones since then all fine but ... I get the old 5 ah battery around 60 plus euros and I got the power stack 80 plus euros compared to the price and mostly speaking about dewalt I didn't expect this kind of cheap and low quality things I mean the hole screwdriver fell from the first floor and it didn't have a scratch but the battery fail in a week and when I opened the battery I notice the the switch has a spring and put pressures to the hole front of the case and with so short screws if you hit it somewhere it not difficult to Crack. Otherwise from power the moment I change to power stack the impact driver became more nervous more power

[@ickess]

I’m torn between this impact wrench and the next generation kobalt 24 mid torque. It’s rated higher than the Dewalt but it’s also bigger. I do like the compact size for working on my car. They are both on sale right now. Currently, the kobalt is at 1:49 with the battery and charger. The Dewalt is currently free if you buy a two battery and charger kit for 199.

[@L0n3S0m31]

Can you do a review on the Milwaukee m12 1/4 impact driver!!!!!!

[@MatthewHeiskell]

Thanks for the tip about the free battery! Somehow I missed that. Just placed another order. I'll be returning the original tool only.

[@nismomike3182]

Do you think the Powerstack would have performed similarly to the 5ah if you had done the 3 additional fasteners?

[@Shoptoolreviews]

It does. We tested more fasteners than what we showed. Thanks for watching.

[@HitLeftistsWithHammers]

Waiting for Milwaukee to respond. Will be waiting a while I expect. 😆

[@peterdragon6367]

I got the 2 pack power stack for $179 but it came with a free tool so I picked up the impact wrench. So I got the 2 power stack batteries and the impact wrench for $179. This is 2 years after the video came out though

[@eaglemedia19]

Do you have got a link for the tool from 8:30?

[@emsbyday]

Just picked up one of these (bare tool) to use with my existing 4.0Ah battery. In all your tests you seem to use 5.0Ah batteries. Tested it out taking off wheel lugs tightened to 150lb/ft and they came off, but much longer before they spun than I expected. Should there be a big power difference with the 4.0?

[@andrewk8636]

Tightened to 150ft lbs doesn't mean removal is at that. Lug nuts can gall on to the wheel and it takes a good amount more to remove than to install them

[@Paul_Dalangpan]

Please, oh please, for us nonprofessional full time mechanics, can you test the new Ryobi high torque, model # PBLIW01? I'm aware that you disassemble one a few months ago, but would really ultra appreciate you testing it on the same rig. Thank you in advance!

[@dustinlucas941]

The tool has 450 breakaway torque, which means the instant you hit the trigger that instant torque is 450 once you hold the trigger and continue hammering its no longer 450 ft lb you need to bumb the trigger a few times to get the full range of torque it has I personally think it would have removed the 500 ft lb nut.. but I could ve wrong.

[@jaminjames33ify]

I got one for $150 with the power stack battery and charger a week or two ago

[@mikethetoolman8776]

any news on a bigger more powerful 1/2 impact to replace the 899 BL impact?

[@Shoptoolreviews]

Not yet, but hopefully very soon. Thanks for watching.

[@robertop2010]

I wonder if the 6ah with 21700 batts does better.

[@crforfreedom7407]

It does, and I would imagine with far less fire risk than these flat-stacked batteries. I just saw where a Tesla burned down the house it was in. No thanks...

[@loucifer323]

Thanks for lowering the volume

[@ZeGermanHam]

I think that was their microphone melting, not an active change made during editing. It would be nice if they lowered the gain on the the audio overall, as Tim's voice gets clipped during just about every video intro he's ever done, and any other time in the video when he is speaking more loudly.

[@mikethetoolman8776]

basically the 901-903 in 20 v versions?? have not seen pricing on the new batteries anywhere?

[@Shoptoolreviews]

PowerStack is $119 for one, and $179 for 2x.

[@johnsmith-qz4bv]

great video ..im thinking of buying one to take lug nuts off and axle nuts....

[@7dioclau]

Let's go Tim. Put my money on reg 5ah battery!! 👍 18v milwaukee compact vs new 20v dealt atomic Or 12v milw vs 12v dewalt 👍👍

[@Shoptoolreviews]

I think the 5Ah will have a longer runtime, but it definitely doesn't outperform in the power department. Thanks for watching. We'll compare these soon.

[@virtuelspeaker]

Or stubby against "20v" atomic ;)

[@guyconnell2250]

I've been eying this impact. Pretty impressive in a very compact tool. I just wish I was in the Dewalt battery platform.

Just got one a few months ago, absolutely love the tool! Can access far more places easier than before without compromising the torque I need. Great tool!
