Homebrew PCBs

Jan, I also tried re-grinds once to go cheaper on buying so many carbide
bits. What I found was that carbide bits usually break before they go dull
because they are so brittle. In my experience, re-ground bits had a very
short life due to premature breakage. There is no way to know what abuse it
has already gone through before it was reground. At first, I thought I had
something on my CNC askew and causing the problem, but checked and double
checked and then tried new bits. Voila! problem solved.
