I agree with the end mill holder and set screw,,that is what I use on the CNC.I do not however use end mills with flats or Weldon shanks often.Seems to always work fine.I think if it slipped,it would break,like right away.So the set screw and holder must be good enough.Albeit larger sizes in steel, the flat probably would be a necessary thing.
