I spent two days drilling 26 small holes in 5/8 inch steel flanges on a steel beam. Each hole took at least 10 minutes and I killed my hand by applying pressure. The holes didn't look good overall. I had to drill 26 more and bought this magnetic drill. With the new drill, I drilled all the holes in record time, about 12 seconds per hole. The drill stayed sharp even in the end. It was one of the best places to shop!
