Which one should I keep DCF512B or DCF503B or both?
The 512B cost $88.85 and the 503B cost $86.93. Auto working is probably the skill utilizing power tools that I am least comfortable with.
I will say that I'm not wild about the 1/2" anvil on the 512B, but I've read that it can be changed out.
As for the 12v line, I've got a few 12v tools now and my justification is I have a few things like a light and radio that are 12/20/60, and the 12v drill is a nice change of pace over my 1007. I always grab the 12v impact over my 860. Something about that 12v impact when it drills is a thing of beauty. It's like hypnotizing in a good way if that even makes sense. It's not too late to back out of the 12v ecosystem altogether (still within my 90 days), but I've gotten some seriously good deals on the 12v tools that I have.
