Buffing and deburring wheels have ratings like 7P, 9P, 2S, etc., which doesn't seem to correspond to grit ratings.
For example, I see a 7P wheel with 180 grit, and a 7P wheel with 320 grit.
I think these relate to hardness, but wondering if someone can explain or decode them -- and how they would be used.
Thanks
