Question: hi! what´s the real voltage of  the drill it is 18v or 20v because the information on the title is different of  the Technical Details
Document: This is my third DeWalt cordless drill and they have all performed very well. This latest one has great power, good battery life and is as durable as ever. Will continue to buy these drills.
The hard plastic case is what it is - nothing revolutionary there. I wish it had a bigger spot for some drill bits or drivers though, but not a deal breaker by any means.I would absolutely recommend this drill to any serious DIYer or home improvement professional.
Drilling through aluminum/wood/fiberglass repairing a boat  calls for long &#34;wide open/full throttle&#34; drilling action (i.e. 1 hole  for a bolt can take 5-8 minutes to drill). All in all I may be getting a full working charge out f the battery, I am just not realising it.
First off, this drill is the same exact drill as the DCD985L2. That drill was discontinued by DeWalt, and this drill is its replacement. It is the exact same drill and the only change is that the batteries included with this drill are the 4 Ah batteries, instead of the 3 Ah that came with the DCD985L2. It's slightly heavier with the 4 Ah batteries, but it lasts longer between charges so the tradeoff is worth it, in my opinion.The build of this drill is solid.
This drill tackled the job of drilling through the metal, wood, and fiberglass with immense ease.Two minor things that I have encountered that you may want to consider. First, when using the t-handle, in some positions it blocks the LED light. Secondly, but this could be due to the use that I have put it under, the 4ah batteries seem to get drained quickly. Comments on that critique however.
I had my eye on this drill for a while and i finally poinied up and purchased it. I was then kicking myself for not purchasing it earlier! I had been relying on a old (but extremely faithful) Black & Decker 12V Drill. What an upgrade! There is no shortage of power at all. The 3 speed transmission allows for easy control of bit speed and power and the 3 drilling modes provide unlimited versitility for all material surface types.
Many years ago when I first started installing security system, I purchased the cheap off brand equipment. I found that I was spending more time to just drill a hole in what ever, and replacing the broken tool when the job over powered the tool's capability than it cost me to spend a little more money for a professional tool. The DeWalt as well as a few others do cost more, but well worth the money.
Absolutely fantastic. That's all I can say about this drill. The 4Ah batteries make this thing a bit heavy, but you never have to charge it!! I have used it a couple times a week for two months now and have still only charged the batteries once.This drill also has a TON of torque. It can seriously hurt you if you're not careful. However, this is definitely a good thing if you want to use the drill as an impact wrench (like I do).
You will not be disappointed.
The light is a bonus that helps out in dark spaces, and I love how the light stays on for a short time after the trigger is released.
