3M 7100219220 Shop Roll 320 Grit 2-3/4 in X 13 Yd

Product Description

The 3M 7100219220 is a ceramic aluminum oxide shop roll designed for precision sanding and finishing tasks in trade and industrial settings. At 320 grit, it delivers fine abrasive action suited to surface prep, blending, and light stock removal on wood, metal, and composites. The roll measures 2-3/4 inches wide by 13 yards long, giving technicians and finishing professionals a flexible, cut-to-length abrasive format. The C-weight paper backing provides a balance of conformability and durability, and the hook-and-loop backing system allows the roll to attach securely to compatible hook-and-loop backing pads and tools without adhesive.

This shop roll is commonly used in woodworking shops, metal fabrication environments, and finishing bays where controlled, repeatable surface conditioning is required. The 320 grit designation makes it appropriate for final prep passes before coating or sealing, as well as intercoat sanding. The cut-to-length format accommodates a wide range of hand sanding blocks, inline sanders, and custom jig setups, making it a practical stock item for shops that process varying part geometries.

Key Features

• 320 grit ceramic aluminum oxide abrasive for consistent fine finishing performance
• 2-3/4 inch width by 13 yard length cut-to-length roll format
• C-weight paper backing balances flexibility with tear resistance
• Hook-and-loop backing for tool-free attachment to compatible pads and sanders
• Blue ceramic grain engineered for durability and extended cut life versus conventional aluminum oxide

Compatibility

Designed for use with hook-and-loop compatible hand blocks, backup pads, and power sanding tools that accept 2-3/4 inch wide abrasive rolls or cut sheets.

Installation Notes

Cut the roll to the required length using a straightedge and utility knife or dedicated abrasive cutter for clean, square edges. Ensure the hook-and-loop backing pad is free of debris before attaching the roll to maintain full contact and prevent slippage during use. When used on power tools, verify the tool speed rating is appropriate for the abrasive format. Replace the roll segment when loading or glazing is observed, as worn abrasive increases heat buildup and reduces surface quality.
