Grigg, I've tried that several times so far with a grinding wheel, so far hasn't worked out. I'll try a cutoff blade next time.
btw there are fine and coarse wheels for the DD.

I was suggesting cutting off a 1/4" or 1/2" or whatever part of the drill is bad with the cutoff wheel to save time. Then still use the grinder to get it back in approximate shape before truing it nicely in the doctor.
I have a fancy version of the Drill Doctor at work, a Darex V390
It's a great machine but still more efficient to rough out nasty chipped or burned ones on the belt sander or grinder first.
