3M 7000121664 Surface Conditioning Disc 5 in Very Fine

Product Description

The 3M 7000121664 is a 5-inch diameter surface conditioning disc designed for general-purpose finishing, blending, and light material removal on metal, composite, and painted surfaces. Built with aluminum oxide abrasive mineral on a non-woven nylon web, it delivers consistent scratch patterns and surface prep results without loading or glazing. Rated Very Fine grade, it is suited for finishing passes where controlled cut and a uniform finish profile are required. HVAC sheet metal fabricators, plumbers working with copper and steel pipe, and general maintenance trades use this disc for deburring, weld blending, and pre-paint surface prep.

This disc is used in residential and commercial trade applications wherever consistent surface finishing is needed before coating, brazing, or assembly. The 5-inch format fits standard right-angle grinders and disc holders common in sheet metal, mechanical, and plumbing shops. It is sold in packs of 10 discs, with 100 discs per case, making it practical for shop stocking or job-site supply. Very Fine grade is appropriate for final-pass blending after coarser stock removal is complete.
