Well you can buy a lot of hole saws for the cost of a hydraulic punch but there are some situations where space constraints don't allow the use of a holesaw bit and a drill. A guy in my shop scored 2 punch sets on ebay- one for himself and one for the shop. I have used it and its a great set. Don't use it for 3/4 much, but for 1" and over you can't beat them for speed and clean holes. I know a two inch holesaw is cheaper but why subject yourself to the abuse of trying to drill a hole that size through metal? I'de save the holcutter bits for drilling pilot holes for the hydraulic punch.
