This is very misleading. This 1st gen (DCF809) atomic impact driver is much different than the 2nd gen (DCF850). Lowe's doesn't have atomic, in this case I think you're talking about DCF840, which I would consider in the middle of the two atomic drivers in performance.
The 2nd gen is much better/faster/stronger and can be seen used side by side with XR tools which have been always been the high end of Dewalt tools.
2nd gen has a physical speed switch vs only the variable trigger, 2nd gen is much shorter/stubby, and (subjective) the motor ramp up is quicker/snappier.
For raw numbers you have:
DCF809...........DCF840.........DCF850
2800 RPM.......3200 RPM......3250 RPM
3200 IPM.........4200 IPM.......3800 IPM
1700 in-lbs.......1700 in-lbs.....1825 in-lbs

The 2nd gen (DCF850, the one listed here) is worth about $100, the 1st gen (DCF809, Ace for same price in a kit) ADN DCF840 are worth around $70 as bare tool. None are necessarily bad, but the 2nd gen is better than 1st gen in nearly every way. The DCF840 with it's higher IPM could be better if you're only driving small-medium screws all the time, but the DCF850 wouldn't be far behind and will catch up when fasteners get bigger and tougher.

DCF787 is basically the older version of what the DCF840 is currently.

DCF787 was the basic brushless model, with the older DCF887 the higher end XR model
DCF787 is probably comparable in performance to the DCF809, but I would probably go with 809 just because it's a bit newer. I would put the DCF840 above both 787 and 809.

For just building up/starting your power tool set, $99 I would think probably be best spent on the DCF840D1 [lowes.com] or the DCF850 listed here if you want something little stronger (you would still need a battery and charger though). There is also a set with a drill AND impact driver w/ 2 batteries for $149 at Lowe's that is a pretty good set for the price, DCK227D2 [lowes.com].

For comparing different models/kits:
If the last letter is a "B" it's tool only.
The last letters in the part numbers I just listed, "D1" and "D2" are indicating the batteries, the letter "D" is the battery (the 2ah) and the number is how many.
DCK are kits "Dewalt Cordless Kit", DCD "Dewalt Cordless Drill", DCF "Dewalt Cordless" impact (not sure where the "F" comes from, but they're impacts), and many others
There are many little things like this that become easy to spot if you're buying/using the tools a bunch, I've pretty much stuck to Dewalt stuff and now know their stuff pretty well.

Same price at Ace Hardware and Lowe's but you also get a 2Ah battery and charger. Model number seems slightly different but they all are Atomic 20v brushless.

[QUOTE=Frugaloid;181066198] I don't think Lowe's carries the Atomic line. But I know HD and lots of other smaller licensed retailers do.

This model is a slightly newer version and is smaller or shorter than the combo set you mentioned. They are both good brushless impacts, just the 850 model is shorter by about an inch, so better in tight spaces. Most people would be better off buying the set from ACE. Lowe's doesn't sell the Atomic version; they have some others, though.

The whole point of the DCF850 existing is that it's their smallest. The one from Lowe's is not. DCF860 is smaller and more powerful than that one and DCF850 matches the specs of their previous top dog while being the smallest. Anything else is just an older, bigger, model.

Bomgaars has DCF850P1 for $99 (comes with charger and 5ah battery). I have had luck getting HomeDepot to price match Bomgaars in the past. I got the DCF850P1 for $89 earlier this year.

I was in a tight space the other day and thinking that one of these would be useful. For $98, why not? Plus I think it's finally time to upgrade to 2 drills and 2 drivers for those times when I have to keep swapping bits.

If it comes with a lanyard, 100% fake. And if it has Phillips screws holding it together, it is fake.

Thanks for the update. Will check w/ my other Dewalt impact driver to verify it's the real thing.

Dang it...i think i bought a fake as the guy only has (2) feedback ratings. 🤡 move on my part for not checking reviews before ordering. Thanks for the heads up.

Hi tool expert person, how does the DCF787D1 compare to this impact driver (DCF850B)? The DCF787D1 is on sale at Amazon for $99 (with 10% back with Amazon Visa) with a battery included. Thanks!
