SIGNI 4-Inch Green Grinding Stone with 5/8-11 Thread (24 Grit)

Have a lot of stains on my flag stone in the yard that I couldn’t get out with power washing, with this they grind out leaving a smooth surface (120 grid)

Excelente producto me facilita mi trabajo estoy muy feliz de comprarlo

Trying a lighter ceramic disc, this was good but a bit heavy for prolonged use

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.

This wheel had more than 0.110 inch of "Total Indicated Runout", the threaded insert was not installed straight or centered properly.For my application it worked because this was a consumable wheel for truing and dressing a resin bond diamond wheel for a cylindrical grinder.This silicon carbide grinding wheel was mounted on the workhead spindle and rotated at 200RPM and successfully was able to dislodge grains from the diamond wheel.But a lot of this silicon carbide wheel needed to be ground away before the runout was eliminated.

Good for work

Used this on granite to shape edges and deburr before using polishing pads. Works great

I installed my own granite countertops in the bathroom. This worked great to smooth out the rough spots after cutting. Then I polished them up nicely. First time trying it and it was a success.
