I have used step drills for decades because they are so handy for working with sheet metal. The one I used was late in life so I took this one. There's a lot to choose from (I only had one bit originally) and the carrying case is quite nice. They're great for sheet metal and gutters and cut great. With a wide range to choose from, it's almost all you need. Some of them also make great wooden countertops. A great addition to any tool bag.
