[Rockhounds] Suggestions on harsh grit 'galaxy' style diamond wheel for genie?

[Robin Albert]

If you are going to do a lot of grinding, consider getting a sintered
wheel.  I have heard very good things about this company out of Lithuania:

https://www.baltic-abrasives.com/en/lapidary-wheels/sintered-wheels/

I had just replaced my 80 grit on my Genie before I learned of them, but
several people I know have bought them and speak highly of them.  They are
very responsive to emails.
