I was cutting a 4.25" x 3" rectangle of CFC and once again the 1/8" carbide emdmill without a flat for the endmill holder to lock down dropped loose, I think because I was cutting too fast, provoking vibration. (25 inches/minute at .001" cuts.) Fortunately, it had completed the last cut when it fell out. This time 1 inch/minute. Slow, but I can safely leave it running and do something else. I am tempted to mill a flat on the shank. Apparently, small carbide endmills usually lack a flat. It is possible to make a flat with a diamond tool. I do not have one. I believe you can cut carbide with carbide. At worst, I break the endmill that needs the flat. These are not hideously expensive and arrive next day.
