One-stop chart/info for Norton grinding wheel specs??

[Jamie Straw]

Hi, all. Am hoping someone has a link to one-stop place for info on the different Norton grinding wheels -- a place that would have not only the grits of the 32X and the SG wheels, but also the hardness (J,K,I). So many of the vendors who carry them don't include this info.

TIA!!

This brochure has some pretty good info:

The first chart is on "Bench and Pedestal Wheels", showing "good, better, best" and grit chart.
