3M 7000121012 Scotch-brite Hook-it Finishing Disc 5 Inch

Product Description

The 3M 7000121012 is a 5-inch non-woven hook-and-loop finishing disc designed for light to moderate surface preparation on metal, plastic, wood, and fiberglass. Built with a silicon carbide abrasive mineral and a 3D non-woven fiber structure, this disc delivers consistent cut and finish throughout its service life. The ultra-fine grade makes it well suited for satin finishing, scratch blending, light cleaning, and deburring without aggressive material removal. It attaches and releases quickly via a hook-and-loop fastening system, reducing disc changeover time during production or service work.

This disc is a practical choice for metal fabricators, auto body technicians, maintenance crews, and finish carpenters working on aluminum, stainless steel, and other metals. It also performs on plastics, wood, and fiberglass surfaces. The conformable non-woven construction allows the disc to follow contoured and hard-to-reach areas, making it useful in both flat surface work and irregular geometry finishing applications where consistency of finish matters.
