Maybe, but take away the battery and all you have left is a horrible hammer

Fixed it for ya

So basically, i ended up buying the drill, again, good buddy and good deal, still expensive, but worth every cent. Talked to dewalt, they told me while the Battery is 20V, but what comes out of the chuck is 18V. I then inquired as to with an 18V dewalt drill, what comes out of the chuck, in which case the rep didn't know because they don't have the specs. The model i have doesn't have the batteries with fuel gages, they are just JUST bringing out that stuff now. ALthough from what i have read, other companies have brought that stuff out already, so why Dewalt is following instead leading as usual i don't know

So a buddy of mine is offering me a great deal on this http://www.amazon.com/DEWALT-DCK290L2-20-Volt-Li-Ion-Hammer/dp/B0052MIJN6 because he bought one then lost the receipt and then his wife bought one for him and lost the receipt. My question is, do i wait for the next evolution of dewalt tools because i have heard that the 20V is just the Dewalt Marketing department overhyping the 18V? Noob here to all things tools and home improvement so more info is better but please keep it clear cut
