Considering the very low percentage of shop time spent with
tools actually in contact with a grinding stone, the
speed difference (in terms of time saved) is not worth
considering.

I wasn't referring to time saved but that more metal is removed from
the tool in the same time when the wheel is spinning faster than when
it is spinning slower.

If that is not true, then why not use a staionary stone? It should be
just as fast to sharpen a tool on a stationary stone as on a grinder,
if I understand the argument being made... that the RPM of the grinding
wheel is not relelvant to the speed at which one can sharpen a tool.

If there's no difference between 1725 and 3450, why would you expect a
difference between 0 and 1725?
