I am a metal artist and find these abrasive wheels are perfect for my artwork. The coarse wheels I use to rough shape my stock while the 80 grit put a nice finish that cleans up my welds. Occasionally I use the 120 grit wheels when I require a finer finish. I have used other brand wheels that don’t seem to perform as well both in ability to remove unwanted material or last as long. Thank you for making such a great wheel. Bill Councell. Rust Bucket Metalworks
