These Bonded Abrasive Wheels are designed to quickly polish narrow and eased edges up to 3/8” (10mm) on thin sheet glass with the Alpha® Edgecrafter. For wider applications, we recommend using Resin Bond Diamond Polishing Wheels for Glass. The long lasting Bonded Abrasive Wheels for Glass holds up to sharp edges and corners commonly found on thin sheet glass. In addition, the polishing process is less time consuming since there are only two grits and a final polish stage.
