Yes, I think you are right there.
After all, why are there resharpened bit on the market
at all ? Well, *someone* finds them adequate, of course :-)

Well, I'm a bit less optimistic about this then when
I started thinking about it.

Well, well, we'll know in a few days. Just for your
enjoyment, I'll post whatever will be the outcome
of this. Of course, I was hoping to make me a fortune :-)

B.t.w, when they was producing PCB's at full speed, I
remember seeing *barrels* filled with "used" bits. Must
have been 100's of 1000's of them. I wonder what happend
the them...

And I'v seen the large Excellon drilling machines running
at full speed. It was more of "punching" holes then drilling.
I think they drilled over 5 holes per second through 3-4 stacked
PCB's. Impressive...
