320 Grit Silicon Carbide Sanding Sheets

These 3M sheets use silicon carbide abrasive on A-weight paper backing for very fine finishing. The tan colour identifies the 320 grit grade in the 99421NA series. Each sheet measures 11 inches by 9 inches for hand or block sanding.

320 Grit Grade for Very Fine Finishing

The 320 grit rating determines the surface finish this sheet produces. It removes light scratches and prepares surfaces for final coats without aggressive material removal. Finer or coarser grades require different sheets.

Pack of 250 Sheets for Extended Use

The package contains 250 sheets, providing ample supply for repeated sanding tasks. This quantity supports multiple projects or high-volume workshop demand. Smaller packs would need frequent replenishment.

Questions about this item

How does the 320 grit rating translate to surface finish on a real job?

The 320 grit rating produces a very fine surface suitable for final sanding before finishing or between coats on wood, metal, or painted surfaces.

What does the silicon carbide abrasive and paper backing mean for how the sheet wears?

Silicon carbide cuts fast and stays sharp on hard materials, while the A-weight paper backing provides flexibility for hand sanding contours without tearing quickly.

Will the 11 by 9 inch sheets fit my half-sheet sander or sanding block?

The 11-inch by 9-inch dimensions match standard half-sheet sanders and common sanding blocks, so they clamp securely without trimming.
