product description
These high-performance 7-inch sanding discs are engineered for heavy-duty stock removal and surface leveling. Featuring a premium zirconia alumina grain, the BlueFire H831 series is designed to cut faster and last longer than standard aluminum oxide abrasives. These discs are “Paper UP,” meaning they utilize a heavy-weight paper backing that provides a flat, consistent surface for professional-grade floor sanding and woodworking. The Pressure Sensitive Adhesive (PSA) backing ensures a secure, peel-and-stick application to your equipment while allowing for clean removal.
