Used but new?
I am sure the drill is great. Much heavier and torque than my one of over 19 years that I love. I needed the upgrade for the hammer drill for framing a couple of medium size rooms into concrete. What annoyed me, I got it for Xmas from the family (I chose it) but it came with no box or manual. Do I really need these things, no, probably not. It does suggest that this was a returned item. Also fine, it appears unused, no blemishes at all, but I paid for a new unit. Might return it, just to make sure I get what I paid for. Really hate when Amazon tries to pawn off returned items as new, without the proper packaging.

So far good product. 01/2026 Update.
It works great! 01/2026 - Update: It will not disengage from hammer-drill mode. I took it apart and the problem is in the chuck side of the drill head. I removed the hammer-nubs and it works fine as an ordinary drill. I recently purchased a DeWalt SDS hammer-drill, so, I’m covered for both uses. If you are an average/semipro user, a DeWalt fits the need for the price. As a pro user I suggest the hi-er-end DeWalt or a Hilti hammer drill.

Rugged, powerful, outstanding drill & battery line.
I'm very late to the Li-ion battery portable tool revolution, and am glad I landed on the DeWalt 20V product line. The drill is vastly superior to my very old Bosch rechargable drill, not even considering the upgrade to hammer function, which is welcome. I appreciate the knurled metal check with its full 1/2 inch capacity and strong grip. This looks to be a drill that will carry me for well over a decade. But hey, Amazon... why are you shipping it loose in a plain brown box, with just paper manual and belt clip? If you're sending a product in the manufacturer's own packaging, make that clear to the buyer. For the record, the drill is brand-new, had no signs of use, and is labeled made in Mexico. I ordered in July 2024, the drill was built in 2023.

High performance Dewalt '805' compact drill
Fantastic amount of torque. I jokenly say it is a 'wrist breaker'. Would recommend this tool. Be sure to get the part number having 805 in it.

Dewalt Quality
Haven’t used it much yet but it is a typically good Dewalt. The smaller size is great. Not any louder than any other drill. Great torque, a little heavy with the 4 amp battery but that is expected. I don’t need a hammer drill but the price was right & it gives me the feature if I ever need it.

Good hammer drill. Needs a way to attach a side handle
I bought this for a small project that I would need to put in several concrete anchors for a fireplace surround. Regular drills just won't cut the mustard for drilling concrete. The drill, like most Dewalt stuff is well built and feels sturdy in your hand. It drills concrete anchors of up to about 3/8 of an inch with no problem but most decidedly needs a side handle attachment for the torque required for larger holes. Doing some research I found there is no side handle attachment that can be added, either OEM or aftermarket as there is no good place to attach one, even those that have the metal band that tightens down. Overall its a good unit for the average guy who needs that extra power to drill concrete or cc blocks but if you need to drill bigger holes or were going to use it all day for work I' say jump up to the bigger unit with the side handle. It costs a bunch more but would be worth it as a contractor. Battery life seems pretty good with my existing dewalt batteries but I found the 5ah battery had more power and lasted much longer than the standard 2ah battery. I have actually found myself using this in place of my drill driver for most applications as it just has more oomph.

La verdad, para los pequeños trabajos que hago es una gran herramienta. Sólo de verlo te enamoras, gran poder, ergonomía, peso, calidad. La luz que tiene es de gran ayuda. Por 2k de precio ¡Inmejorable! Espero que me dure muchos años funcionando bien. Lo recomiendo ampliamente. Ah! Me enviaron una maleta Dewalt de regalo que no incluía en la descripción, gracias. Cabe perfectamente el taladro, el cargador y dos baterías power stack.
