3M 7000118534 Abrasive Shop Roll 400 Grit 2in X 50yd

Product Description

The 3M 7000118534 is a 400-grit aluminum oxide abrasive shop roll designed for fine surface finishing, deburring, and surface preparation across metal, wood, and composite substrates. The roll measures 2 inches wide by 50 yards long, providing an extended working supply for high-volume shop use. A J-weight cloth backing delivers flexibility for contour sanding while maintaining tear resistance under moderate pressure. The extra fine grit grade makes this roll well suited to finish sanding and light stock removal ahead of priming, coating, or polishing operations. Machinists, fabricators, HVAC sheet metal technicians, and general trade professionals routinely keep shop rolls on hand for field and bench work.

This abrasive shop roll is used in light industrial and trade shop environments where consistent, controllable material removal at fine grit levels is required. Typical applications include cleaning weld seams, smoothing pipe ends, deburring sheet metal edges, and preparing surfaces before painting or adhesive bonding. The flexible cloth backing allows the roll to wrap around curved or irregular profiles, making it practical for tube, conduit, and pipe surface work common in plumbing, HVAC, and electrical trades. Cut strips or sleeves to length as needed for hand sanding or mandrel use.

Installation Notes

No power tools or energized systems are required for basic hand-sanding use. When used with a powered drum or spindle, ensure the mandrel arbor is properly secured and the roll strip is tensioned evenly before operation. Wear appropriate eye protection and a dust mask rated for the material being abraded. Dispose of used abrasive material in accordance with local shop waste guidelines, particularly when sanding coated or treated metals.
