3M 7000120998 Quick-change Disc 3 in Aluminum Oxide Very Fine

Product Description

The 3M 7000120998 is a 3-inch non-woven aluminum oxide quick-change abrasive disc designed for use with Roloc TSM Type S attachment systems. Rated to a maximum of 18,000 RPM, this disc carries a Very Fine grade designation and is identified by the AVFN specification code. Its non-woven construction blends abrasive mineral throughout the fiber matrix rather than coating a backing, which delivers consistent cut rate and surface finish as the disc wears. The blue disc color and silver button are standard identifiers for this SC-DM series product. Licensed trade professionals and fabricators use this disc for surface conditioning, light material removal, and finishing on metal and similar substrates.

This disc is suited for surface preparation and finishing tasks in commercial and industrial shop environments as well as field service applications. The Type S Roloc TSM attaching system allows fast disc changes without tools, making it practical for high-turnover tasks on HVAC ductwork, pipe, structural steel, and general sheet metal fabrication. It is a single-piece package sold individually.
