36 volt? That's crazy. 6.9lbs for the drill. At least they designed the Dewalt 36v battery to weigh the same as their 18v designs (2.4lbs). Shouldn't kill your arm or shoulder too bad to work with these new tools.
If I used them daily for work, I'd probably step up to an 18v or maybe the Milwaukee 28v system. But for occasional use, I cannot complain about my Makita 12v system, even though most of my batteries are now 3+ years old.
I used the 12v drill and a step-drill bit this past weekend mounting the Superwinch on the trailer. It cut several 3/4" and 7/8" holes through 1/4" aluminum, plus one hole through the 3/8" c-channel frame, and three more in 1/8" or thinner, for the wiring, vent tubes, cut-off switch, etc. On the 1/4" stuff, it bogged down pretty good once you got to the 3/4" step and breaking through the 7/8", but it pulled through like a champ. I have used this same drill and bit in 1/8" steel with good results. I think I went through 2, maybe 2 1/2 batteries, on the whole project, which involved 8 holes with the step drill, plus a few 3/8" holes with a regular drill bit going through the 6061 aluminum winch-mounting plate. I'll post some pictures of the project results this weekend.
