Toolocity GSB0060G 4 Inch Grinding Thread Review

When I opened the box this part was inside, obviously it was a second rate manufacturing defect as there was a vertical score on the front of the grinding wheel which would have looked quite obscene. Craftsmanship in the rough profiling of marble. Unfortunately I missed the return window by 3 days due to the current pandemic and family issues which has lasted over two weeks. I ordered 3 different grinding wheels in different grits and only one was usable. Do yourself a favor and look elsewhere!
