To a rough approximation, how long should a diamond wheel last if you
are working granite? I imagine it depends on a lot of things, such as
on how you use it, the quality of the wheel, when you consider it worn
out, etc. But about how long is reasonable? 10, 100, 500, or 1000 hrs?
Does this time, say, double, on a softer stone like limestone?
