This is just because I am curious. I don't use my tools for my livelihood or anything and I have no strong opinions on it. I remember buying a 9.6v drill at a discount when the 12vs came out 20+ years ago. Didn't seem like the lower voltage tools stuck around much after that, as far as I remember. Now it seems most manufacturers still offer 12v and 18v tools simultaneously. Seems like more people go for the bigger ones -- I guess most people think it is better to have the power and not need it. Or maybe it is just the "more is better" idea as people do with cameras and megapixels, etc. I was thinking of getting a second set of drill/drivers for workshop use only and getting 12v this go around since I don't usually need the 20v hammer drill for worksop projects. And it is always there in the truck if I need it. Anyways, if you have cordless tools, do you use 12v tools, either in combination with 18v or not?
