3M 7100091074 Shop Roll 400 Grit 2-3/4 in X 13 Yd

Product Description

The 3M 7100091074 is a ceramic aluminum oxide shop roll designed for precision surface finishing in trade and industrial environments. At 2-3/4 inches wide and 13 yards long, this roll provides a generous supply of abrasive material that can be cut to length as needed. The 400-grit rating makes it suited for fine finishing passes, light material removal, and surface prep work. The hook and loop paper backing allows the cut sections to attach securely to compatible sanding blocks or orbital tools without adhesive. Ceramic aluminum oxide abrasive delivers consistent cut performance across metal, wood, and composite surfaces.

This shop roll is used in metal fabrication, HVAC sheet metal work, plumbing fitting prep, woodworking, and general maintenance finishing tasks. The C-weight paper backing provides flexibility for contour work while maintaining enough stiffness for flat-surface applications. The 13-yard roll length is well suited for production environments where frequent abrasive changes slow down workflow. Technicians and fabricators who need a consistent, re-tearable supply of fine-grit abrasive on hand will find this format practical for both bench work and field finishing tasks.

Installation Notes

Cut the roll to the required length using a straight edge or shop scissors before attaching to a sanding block or tool. Ensure the mating hook and loop surface on the tool or block is clean and free of debris before attaching the abrasive section. Wear appropriate eye protection and a dust mask or respirator when sanding, particularly on metal or composite materials. Follow applicable shop safety guidelines for abrasive tool use.
