Ok, y'all are going to think I'm nuts but I have no idea. On this set below, what is the difference in each of these that come in this set? I know he said he'd like a good drill, but this one has 2 in it and I'm not sure what is the difference. Also, what about the little thingies that go into it? ROFL. I'm laughing at myself here, but I obviously am not tool oriented.
