The Goodson Tools and Supplies CSS ULTRA Grinding Wheel from Radiac Abrasives provides an alternative grinding wheel composition that minimizes heat build-up. The grit texture is composed of white and sintered aluminum-oxide with a high strength bond. The grinding wheel offers long life, cool grinding, and high productivity. The high strength bond system allows the grains to withstand greater loads during use without premature breakdown, the company says. The bond also allows for increased stock removal rates and reduced friction. It's available in 26" and 28" diameter with an 8" arbor hole. Face widths are available from 3/4" to 2-1/4".
