Question: What differences are there between DCD790, DCD790B and this DCD790D2? It looks to be the accessories and/or battery alone or with a kit that are the main differences I spotted. Any info would be appreciated. Their numbering seems wacky to me.
Document: This drill is everything that I was hoping for when I ordered it. It's lightweight, very durable and lot's of power. Battery seems to hold it's charge very well.
I purchased this drill to replace an old Black and Decker Firestorm. I am really impressed with the power and longevity of the battery.I would recommend this drill for anybody looking for a great new drill.
My only complaint about this drill (other than the price) is several time I have been drilling in steel, usually to enlarge holes, the bit will hang up, get stuck and the drill will then try to break my arm. So far it has failed and only left me with a slightly painful sprain,  I have used plenty of corded drills that would not do that. For the size and weight of this drill I haven't seen anything that comes close to it. So be careful using this drill.
The motor brake is still annoying - it stops abruptly and it's loud. I do like the weight of the drill, the new 2.0AH batteries, and the hard case. Other than that, I didn't noticed much of a difference from the regular 20v drills. I was using the Milwaukee 18v Fuel drill and was looking to replace it with this drill because The Milwaukee was heavy after long use. If you don't mine the weight, I would get the Milwaukee one instead.
The drill also has a spot to clip a screw driving tip but Dewalt didn't include one like in the older drills. Maybe the price should have been .25 cents higher and have included a tip. This drill is not cheap but seems decently built and featured.
I had recently purchased a cheaper lower quality drill and it couldn't even drill a screw into a 2x6. I purchased this and was super impressed. Light and powerful. I still have yet to drain the battery with usage.
Have only used a couple of times as the power source for an ice auger. The temps were in the teens and I was able to drill 30 holes through 10 inches of ice on one battery pack and the drill had plenty of power during all 30.
I've heard very good reviews from other people who use the Dewalt brand....longer lasting, light weight etc. I haven't had it long enough to know how it stands up to tapping sugarwoods all day but it is definitely lighter than Craftsman and smaller in your hand. That will mean alot after I've used it all day! Hoping the battery has a better charge than Craftsman!
The batteries charged as stated. I have no complaints with the keyless chuck holding bits or in battery drain like other models. This drill has plenty of power as long as you don't expect it to replace a 1/2" corded drill. Besides power and lasting charge the batteries finally have a charge indicator showing how much power is left, a Hilti feature. The grip angle and grip size are comfortable with nice balance and the controls for forward and reverse as well as the two speed ranges and clutch easily reached.
Ridiculous power and torque for the size. Very compact and light. Almost 2&#34; shorter from front to back than my old drill. Incredible battery life. Not cheap, but you get what you pay for.
Answer: no
