CGW - Aluminum Oxide 6" x 3/4" Grinding Wheel, White, 120 Grit
Aluminum Oxide Grinding Wheels are a giant step above the conventional gray, hard, slow cutting wheels which tend to burn tools as the grinding surface becomes dull and glazed. Made of granulated aluminum oxide with a vitrified white bond, they allow the grains of abrasive to wear off, thus providing a consistently fresh grinding surface.
