3M 7000121008 Scotch-brite Surface Conditioning Disc 4.5 in

Product Description

The 3M 7000121008 is a Scotch-Brite Surface Conditioning Disc designed for cleaning, blending, deburring, and finishing on a wide range of surfaces. Built with a durable, open non-woven fiber web, this disc runs cool and resists loading during extended operation. At 4.5 inches in diameter and weighing 0.05 pounds, it is sized for use with right-angle grinders and similar tools. The aluminum oxide abrasive construction conforms to irregular and contoured surfaces without undercutting or damaging the base material, making it a dependable choice for fabricators, machinists, and maintenance technicians.

This disc is suited for multi-step surface preparation and finishing work on metal, composite, plastics, and other materials. The hook and loop attachment system allows fast disc changes during multi-step finishing processes, reducing downtime on production floors, fabrication shops, and field service applications. It is appropriate for both light production environments and skilled trade maintenance tasks where surface conditioning is required before coating, welding, or inspection.
