dewalt 12v vs 20v hammer drill

Saturday to make a quick comparison video between the DeWalt 20 volt hammer drill and the 12 volt hammer drill. just wanted to see if the 12 volt could take the place of the 20 volt and according to my video it does not. the 12 volt drill is still good it'll still drill through the concrete but just not as fast but it's still a good tool to have around in an emergency toolbox or whatever but like I said from the findings of my video it is a no where near the 20 volt when it comes to speed and power. this should have been a no brainer but you know we still have to try. lol have a great day folks
