Aluminum Oxide Grinding Wheel (1 Wheel), White, 120-Grit, 6" x 3/4"

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. Sharpening is faster, with less danger of taking the temper out of the tool. This 6" diameter, 120-grit wheel comes with bushings to reduce the arbor hole to fit 3/4", 5/8", and 1/2" shafts. Also available in 8".
