make that "EDM".....

Slow, messy, but does not care how hard it is...

I guess most folks are lucky enough to have sinker style EDM shop
nearby. The only two in my area are wire machines.

But... I can buy a Rockwell drill bit via overnight web-order, and do
the job faster and cheaper than taking it out somewhere.

Or, I can anneal the bolt, drill it, then take it to any one of eight
or ten heat-treating shops around here.
