Review: cheaper solution - This thing is a tank, i used it for beveling 1/2" plate on a 6" grinder.
Review: Great job - When I originally used the grinding stone it was burning the edge of the tile but I realized that the grinder I was using was turning too fast. I put the stome on a tool with the proper rpm’s and it did a great job. Just be aware of the rpm rating on the tool you are going to use.
