3M Company 9413NA Paint Varnish Remover Drill Mount Disc

Product Description

The 3M COMPANY 9413NA is a Scotch-Brite contour surface paint and varnish remover disc designed for drill-mounted use on wood and metal surfaces. Built with a medium-grit Scotch-Brite web, it strips paint, varnish, and surface rust without the need for chemical strippers or hand sanding. The disc measures 4.75 inches by 9 inches by 1.5 inches and mounts directly to standard household drills. It is sold as a unit of measure of each, with a package quantity of 10. Trades that regularly prep surfaces before coating or refinishing will find this disc suited to production-level removal tasks on both flat and contoured workpieces.

This disc is appropriate for residential and light commercial surface preparation work, including paint and varnish stripping on wood trim, metal framing, and rusty ferrous surfaces. It fits all standard household drill chuck sizes including 1/4 inch, 3/8 inch, and 1/2 inch, making it compatible with the most common corded and cordless drill platforms used in the field. It is not application-specific to a single trade and sees use across painting, carpentry, general maintenance, and light fabrication workflows.
