I took a stab at panasonic cordless tools 3 years ago based soley on the nimh battery capassity.What i ended up with was a superior drill that lasts 6+ hours.I am a contractor and i have used this drill every day for the past three years ive owned it.Ive had to send my drill out for a tune up recently,(it diddnt break whatsoever)its nice having a drill that can be used on a daily basis for three years without a single issue. The battery charger it comes with is a fast 45 min charger, so your never without a uncharged battery(if you play your cards right). Now the downside, this drill is heavy but thats what you give up with an 18v drill that has to be understood i wouldnt buy this drill for its weight but if you want the best ,a heavy tool is what you end up with. If you want something lite get an inpact wrench.
br / In conclusion this drill i believe is the best out there for lite masonairy apps like tapcons,the torque is way overboard (it can tackle things most other drills cant like drilling through steel)so you dont have to think twice about corded tools across the jobsite, or out in the box truck.Even though this tool is heavy i still gave it five stars because to me its worth its weight in gold.

I have used many cordless drills and this one is by far the best. It has excellent power and battery life. I would highly recommend this tool to anyone.
