And what makes them out of spec is the length of the shaft plus
bit. This is because the PCB drilling machines are CNC, and have a
fairly limited Z-axis movement.

Have someone clean them and sort out the broken ones, then toss the rest
on Ebay in various lot sizes, for shipping it is handy to stick them
into a styrofoam block with a second one over the tips so they don't get
broken.

Agreed.
