Thanks Rob, Bob, Meldonmech, one of the high points of the year for me to go to that show, and this year I really enjoyed the tool tables!
There a good shaped tip to have Steve , and the amount you have it would be well worth your time to make holders , the thing with that shaped tip is you can make holders so you can use all 4 corners for cutting , so when two are blunt the other two edges can be used in a different holder .

Rob, I thought they were 4 cornered like yours, but the foggy plastic on the box obscured the inserts themselves. When I got them home I saw that they were rounded in profile. I'm guessing they may still be good for finish work, or possibly just right for a fly cutter isert.
Also, maybe I can trade some of them to others for different insert shapes. I don't need 90!
Here's what they look like:
