    This is dewalt’s newest version of their compact brushless drill. I have used the dewalt 771, 780, various makitas, and some other drills. This dewalt is easily the best cordless drill I’ve used. I work in a factory and use lots of drills to drill through steel, stainless steel, and aluminum on a regular basis.The chuck makes anything else I’ve used feel like a joke. The makita and porter cable chucks are not great. The other dewalts at least did not slip with smaller bits, but the metal 791 chuck is on another level. It’s very precise and smooth and grips firmly. The chuck alone warrants the extra cost over the 780. The 780 is only $30 less, which I don’t understand, because it’s much closer to the 771 than the 791. If you’re considering the 780 either save your money and get the 771 which is pretty much as good, or just spend a little more to get the 791 which is a huge step up.The brushless motor is extremely powerful compared to most drills. According to the internet this drill has an output of about 620 in-lbs of torque. In America, dewalt lists their drills based on some arbitrary non standard unit of output. There’s probably some old engineer working there that thinks he knows everything and won’t use the same measurement of torque that everyone else uses but there you have it, 620 in-lbs based on converted European (newton meter) specs. Anyway, if the drill bit snags you’re going to be in for a surprise, at least I was, and I’m not a weak person. The drill whipped right around and if I had a weak wrist it might have hurt a lot. I guess you could say this is a good thing because more torque = more better (right?) but at any rate just be aware that a lot of drills this powerful have an extra handle, whereas this one is meant to be used one handed. It makes me slightly nervous now but I’m just being more careful. Everything else I’ve used that has a brushed motor, I am strong enough to stop the drill if it snags.I can’t comment on the battery life because I haven’t used it enough to have cycled the batteries or even run one of them down all the way. Based on the old model and typical brushless drill efficiency it should be good. It makes it harder to run out of battery when you can check the charge level and keep the second battery charged, anyhow, just pay attention.The case seems well made and everything fits well. I might have liked more room to store drill bits (there isn’t much extra room, and no designated spot that I can see for storage) but the compact size of the case is useful in its own right.The light is very bright and has a few settings, not much to say there, but it’s more useful than most.I can’t imagine there is anything else out there right now that’s better than this drill as far as a compact. I did a lot of research and the next best drill I found was a rockwell that’s also sold here for about as much as the dewalt 780. The rockwell also has a metal chuck and brushless motor, unlike the dewalt 780, making it a better choice in my opinion. Bosch is known to make good drills, however their most recent models of compact brushless drills are reported to have frequent issues with the trigger, and they all have plastic chucks. They are relatively inexpensive though, although the torque ratings on the bosch are quite low (in the 400’s in-lb) which is even weaker than the rockwell (530-ish in-lbs) and much less powerful than the dewalt 791 which appears to be the most powerful compact brushless available.That about sums it up, if this drill is in your budget I don’t think you can go wrong, if your budget is limited get the 771 because it is half the price and works fine, especially if it’s not being used in an industrial setting.

    I bought this drill with some reservations. I have a full cabinet of 18v Dewalt tools whose batteries are slowly dying and figured I could start using these 20v batteries and the DCA1820 battery adapter that Dewalt came out with to extend the life of my old tools. So I wasn’t sure how much I would use yet another cordless drill added to the multitude I already have.Power wise, this drill is not noticeably different than my other drills. It does feels faster when pushing a bit hard, but my old 3 speed drills applied enough force to burn up or ruin most drill bits. What I love about the DCD791 is how compact it is. It’s nearly half the length of my old 18v drills. Its nearly as compact as my driver. I was also looking at the larger brushless DCD991, but the compact size of the DCD791 is such an advantage that unless I was mixing mortar or boring really long holes often, I would prefer the compact drill. I used this recently to drill some sheet metal HVAC ducts in a tight space, and it was great not having to use my right angle drill.Dewalt incorporated a lot of good features with the DCD791. I like how bright the light is, and it’s great having the 3 settings. The drill has 2 speeds and while it’s a little rough switching between the gears, it’s less clunky than my other drills and I haven’t had to spin the motor to get it to shift. There are rubber bumpers around the side of the main part of the drill’s housing that help when the drill falls over. The chuck is all metal and grips well. The grip itself is thin, comfortable, and easy to hold tight. This being my first brushless drill, I also like that there’s less noise and no sparks. This comes with 2 DCB203 2ah batteries that have the “fuel gauges” to check your battery life. The charge I received was a DCB112.With all the features, the best thing about this drill is how compact and relatively light it is. But don’t let that give you the impression that this isn’t a powerful drill. The DCD791 is fantastic and I’ll have a hard time switching to larger drills when needs call for it.

    I purchased this XR cordless drill and at first glance appeared to be a quality drill (as you’d expect from Dewalt), but when I placed a bit in the chuck and ran it I noticed a lot of wobble in the bit. The drill chuck had excessive wobble / run-out. I figured I just received a lemon so I returned it and ordered another one, the second drill had even more chuck wobble. I am very surprised that this drill could pass Dewalts quality control. My $99 drill is better than this one! Please be aware of the possible issue with this drill.

    Best drill I ever got. Drilled more than 300 holes for a dock made with 5/4″ cedar and through aluminum plus screwing in #10 screws in it with only one charge of battery.

    OMFG. Compare this drill to the Dewalt 20V that goes on sale at Home Depot/Cdn Tire all the time and its night and day. This is twice as expensive because its at least three times as good and probably 8 times as strong.

    …product to use all around the house. I had an older model Dewalt and it worked for more than 10 years and only resent death of the battery packs pushed me to get a newer drill (nice sale price, btw). Light, powerful and impressive battery life. Highly recommended.

    This XR 20 volt Dewalt drill has a few more features than my original 14 volt drill. The base mounted LED (which works great), the battery built in fuel gauge, and the overall size. It’s also lighter, brushless, and easier to handle.

    Lo compré a la segura porque la Marca por sí misma es garantía. Y efectivamente, es una herramienta de gran calidad, no ruidoso, preciso, manejable, mango ergonómico y el kit viene completo. Sin duda alguna, tengo una herramienta para muuuuchos años! 100% recomendable.

    Thought this drill might be a bit of overkill for a lightweight like me…but it did everything this difficult job demanded of it! I was so impressed with the torque, the handling comfort, the light, the battery life…and the price on Amazon is excellent. Unless you’re buying DEWALT’s new Atomic line (even more compact, less weight, lots of $$$), I think this is the drill you should choose. Highly recommend!

    J’ai utilisé ma nouvelle DEWALT DCDD791 pour refaire le dessus d’un patio de 400 pieds carré et j’ai été agréablement surpris par sa légèreté et sa puissance. La prise en main est très confortable, le bouton de marche avant/arrière est bien placé et fonctionne très bien. C’est un plaisir de travailler avec cette perceuse.

    Much lighter than older 18volt models. Good battery life and very good power for the DIY. The drill is smaller than older models so you canaccess tight spots better. Overall very satisfied.

    My big old Dewalt drill finally gave up after 25 years. Just as other reviewers have said…..tons of power and battery life. Knowing Dewalt I’ll no doubt get another 25 years out of this one.
