3M ProGrade Precision sandpaper uses Cubitron II ceramic alumina grain technology that cuts faster and lasts up to 15X longer than conventional sandpaper. The precision-shaped triangular grains continuously fracture to expose fresh cutting edges throughout the life of the sheet.

• Cubitron II precision-shaped ceramic grain for faster sanding
• No-Slip Grip backing prevents sliding and reduces hand fatigue
• Anti-clogging coating resists loading for extended sheet life
• Use wet or dry on wood, drywall, paint, and metal
• Sheet size: 9" x 11"
• 3 sheets per pack
• Grit: 80
• MPN: 7100328274

Tip: Use 80 grit for heavy stock removal, paint stripping, and leveling rough lumber before stepping up to finer grits.
