3M 7100091037 Shop Roll 80 Grit 2-3/4 in X 13 Yd

Product Description

The 3M 7100091037 is an 80-grit shop roll designed for general material removal, surface prep, and finishing work in trade and industrial environments. The abrasive is ceramic aluminum oxide on a C-weight paper backing with a hook and loop attachment system. At 2-3/4 inches wide and 13 yards long, the roll provides a practical supply for cutting custom-length strips to fit a wide range of hand blocks, portable sanding tools, and contour applications. Ceramic aluminum oxide is a harder, more durable abrasive grain than standard aluminum oxide, making it well suited for aggressive stock removal on metals, composites, and hardwoods without rapid dulling.

This shop roll fits common workflow demands in HVAC fabrication shops, metal finishing operations, plumbing rough-in prep, and general contractor environments. The hook and loop backing allows fast pad changes on compatible backing plates and sanding blocks, reducing downtime during multi-step finishing sequences. The 80-grit designation places this roll in the medium-coarse range, appropriate for initial surface conditioning, weld spatter removal, rust and scale reduction, and removing old coatings before refinishing. The C-weight paper backing offers moderate flexibility, allowing the roll to conform to slightly contoured surfaces without tearing under normal working loads.

Key Features

Compatibility

Designed for use with hook and loop compatible hand blocks, sanding pads, and portable abrasive tools that accept 2-3/4-inch-wide shop roll stock. Verify backing plate compatibility before use.

Installation Notes

Cut strips to the required length using a straightedge and utility knife or dedicated roll dispenser. Ensure the backing pad surface is clean and free of debris before attaching the hook and loop strip to maintain consistent adhesion. Disconnect power from any tool before changing abrasive strips. Inspect the abrasive surface periodically during use and replace worn strips promptly to avoid uneven material removal.
