I know most of you guys never need anything more than your old 7.2 volt stick battery Makita cordless and a step drill, but yesterday I was really thankful for my 18 Volt Milwaukee cordless and my hydraulic slug buster. The problem I've always had with step drills is that you are basically drilling the same hole 5 times even for a smallish half inch KO bushing. Each step is harder than the last. Still, if you only have one, and you are drilling in a horizontal orientation where you can brace into it, its not to bad and often takes less time than going and getting the right stuff out of the truck. It still takes some time, but at the end of a dozen holes in medium gage galvanized steel your arms aren't noodles, and your hands aren't numb from vibration. 1/2" pilot point drill bit with a little Tap Magic cutting oil, and about five pumps with the slug buster, and you are snapping in your bushing and pulling the wire through.
Maybe not quite as handy as the scissor lift, but the next best thing after you are up there.
