3M Xtract Cubitron II 710W Net Abrasive Disc provides twice the life and cut rate, while removing up to 97% of dust particles as it sands metal, wood and composite surfaces. How does it work? 3M Xtract Cubitron II discs contain 3M Precision-Shaped Grain technology designed to continually fracture into sharp cutting edges. As a result of this technology, 3M Xtract mesh abrasives offer twice the abrasive life and cut rate of leading competitors' net discs.
