They come in various hardness levels. The harder ones might last longer when using on steel, but I wanted one that wouldn't cut too aggressively on aluminum. Overall, I am very satisfied, and would buy it again.
I also bought some smaller ones (roughly 1.5" diameter) from eBay, which I used in the drill press to polish that bottle holder I posted a few pages back (pg 540).
So you must have a low speed grinder to run those wheels since the recommended range is 1800-2800rpms with a maximum speed of 3000rpms.
