DEWALT 20V MAX Cordless Drill/Driver Kit, Brushless, 1/2-Inch (DCD791D2)

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.

So far I love the DEWALT DCD791D2 20V MAX XR Li-Ion 0.5" 2.0Ah..Really has a lot of power, metal transmission, and smaller than the 18 volt Hammer/driver and lighter. Only had one problem the bits keep falling out.But i found out how to solve that problem which on my part was like of knowledge . So how I solve that problem as noted: I had the same problem but finally relies I was not locking the drill bit in the chuck holder. You need when you have the bit tighten than keep turning the chuck bit holder clock wise until you hear a click which locks the drill bit in and then the bit won’t come out. But when you need to take the bit out turn the chuck drill bit holder counter clock wise with your hand. You will feel the bit loosen and keep turning until loose enough to pull the bit out. Mine was so lock in that I had to use a big Mouth adjustable pliers to unlock the bit holder but from now on I use a rubber bottle cap loosener to unlock the bit holder so I would not scare the outside of the chuck bit holder because I could not by my hand turn the chuck bit holder counter clock because it so lock in. I even called the DeWalt teck and he said it was OK to do it that way to unlock the bit holder. Just remember to turn it clock wise with your hand to you feel that the drill bit is tight than keep turning the chuck bit holder until you hear a click which locks the drill bit in and secure. Problem solve no more bit falling out!!! Boy does it lock the drill bit in and you cannot pull the drill bit out period! Maybe over time the chuck bit holder will loosen up and will be easier to unlock the bit. Hope this helps.Up Date: I found That if you first turn the chuck counter clockwise until you hear one click to lock the drill bit in it will not fall out but in order to unlock the chuck without using a wrench to unlock the drill bit is to by hand, is to first turn the chuck bit holder "clockwise" until you hear another click which than allows you to turn the chuck counter clockwise by hand to unlock the chuck bit holder with ease, than just keep turning counter clockwise until the bet is loose enough to pull the drill bit out really easy. Even the DeWalt tech did not know that. I just kept trying and experimenting which allowed me to realize how to lock and unlock just using my hand only. You would think the DeWalt directions book would address the way to lock and unlock the chuck bit holder so you would know action needed to insert the chuck bit holder and to lock and unlock! It's realty easy when you know the right Procedures. Hope I explain this good enough to be understood.

I can't express my love for this machine, First I was hesitant buy an expensive drill plus international shipping is not cheap on Amazon, but eventually I decided to buy it anyway. Luckily the package came just within 5 days to Pakistan. As it is common for most tools, I thought it would've been made in an Asian country but as I opened the box and saw "MADE IN USA" label, it really made my day.The kit includes drill with two 2Ah batteries and a charger, all inside a hard plastic case wrapped in a beautifully branded cardboard, I took the drill out and slightly pulled the trigger for the first time, LED light comes on and drill started to rotate very smoothly (not too harsh like other cheap drills), this is the best feeling in hand if you want fine accuracy in controlling the variable speed of drilling. The tool itself feels very tough and reliable in hand but not too heavy to make you uncomfortable, it has very good torque and works well on wood, metal and concrete without any difficulty. I read some reviewer complained about build quality, but honestly I haven't seen any misalignments anywhere on the drill and I would say it is build with great care.I just fell in love with this tool, not only it looks and feels good but also works well. I believe it worth every penny I spent on it, I would suggest buy a quality tool instead of saving money and you will be satisfied like me. The "MADE IN USA" label is my favorite. Thank you DeWALT and thank you Amazon for international shipping.
