I also use a HF long electric die grinder, along with there router speed control and a quality carbide bit. The speed control makes grinding hard materials much easier. I grind on a butt load of stainless and with out the speed control it would eat bits alive.

I have an adj. speed air die grinder.
So, at risk of hi-jacking the thread, where's the best place (on-line) to get carbide bits? Mine are toast...
