The 3M Cubitron II Hookit Paper Disc is engineered for high-performance sanding and stock removal. Featuring 3M precision-shaped ceramic grain, this revolutionary abrasive technology allows the disc to cut up to 2x faster and last up to 4x longer than conventional abrasives. The triangular-shaped ceramic minerals slice through materials cleanly and efficiently, rather than gouging or ploughing, ensuring superior performance and extended disc life. The Hookit attachment system offers quick and easy disc changes, making it ideal for workspaces where adhesive-backed discs may become contaminated by dust. These discs are well-suited for a broad range of sanding applications, particularly where edge retention is not a primary concern.
