quote; Which Drill is good and will last the longest?
What difference does it make if this is a tool for a single job. When you ask our opinion on quality, we have to base it on new tools. You are looking at used drills so its "history" will affect whether it is a good drill or not and how long it will last. Buying something lke that, on the site you checked, is a "crap shoot" because the owner will seldom give you a 'bad review" of his tool. They are ALWAYS "like new" or "good as new", even if they are actually worn out. Many of them, especially Hilti, will use proprietary chisels.
