Sure, but the easiest way is to get a dedicated cut-off blade holder
and cut-off blades for the big stuff. For itty-bitty stuff, I still
grind minis from 1/4" square blanks. Yeah, it takes awhile. Wouldn't
care to try it on bigger blanks, either. I use 40 grit belts on the
belt grinder for roughing, I'd probably see if I could get something
around 20-30 grit for wheels if I was stuck with a bench grinder.
