Also, avoid using any kind of abrasive to open a hole where there isn't one
unless you're trepanning. The center of any stone has little to no surface
speed so it won't cut efficiently, regardless of the speed it's driven.
Grinding wheels, or mounted wheels such as you're discussing, behave soft
when driven slowly, so instead of grinding, they slough off, destroying the
wheel.
