I bought this because I needed to make a peen mark (a dimple) in an aluminum plate that I screwed a valve into (so it won't back itself out). It's a several-hundred-dollar plate that holds 5000 PSI of pressure, and you're supposed to make the peen with a hammer and a standard punch. Not for me.With this, I was able to very carefully and precisely put a peen right where I wanted it to be. It took like 5 punches (without moving the top), but I've got that valve safely locked in place!Price was solid, build quality seems fine. I do not think this is a high-use-volume tool, but if you only occasionally need a precise hole, I would have no hesitation recommending this tool.
