I bought this to use with an arbor press to fit Kydex 1/4" grommets. I was very surprised, but nothing I've tried works with it. You can flare out the unflared edge just enough to maybe hold up a bit, but not at all how it should be finished. To be honest I was surprised at how poorly it worked and thought I was doing something wrong so I tried other studs and different types of pressing but all with the same result.
