Power tools questions from newbie
1. When I went to home depot, I saw a few brands. I think I have heard of dewalt, but the sales guys tried to talk me into buying Rigid power tool. He said Rigid has lifetime warranty and it includes battery. I don't really believe that. How can a manufactory provide a life time warranty on battery? What are the big four brands that people refer to here? Any opinions on pros and cons?
2. What type? What is brushless? Do I need that?
3. Do I need to get 20v or 12v version? People say 20v max is actually 18v. Which one will be good for my home project, like making furniture, drilling holes on walls, wood boards,builting a tree house...
