3M 7010363419 Sanding Disc 6 Inch 320 Grit Aluminum Oxide

Product Description

The 3M 7010363419 is a 6-inch pressure-sensitive adhesive sanding disc designed for automotive refinishing and surface preparation work. Built with self-fracturing aluminum oxide abrasive at 320 grit, the disc cuts quickly and resists loading, extending usable disc life compared to standard abrasive discs. The Stik-It attachment system uses a peel-and-place backing that bonds firmly to vinyl backup pads during use and peels off cleanly when the job is done. These discs are sold in packs of 20 and are suited for auto body technicians, painters, and surface prep professionals working in refinishing environments.

These discs are intended for use with dual-action orbital sanders equipped with vinyl backup pads. The 320-grit aluminum oxide construction makes them well suited for finish sanding applications on paint, primer, fiberglass, metal, and SMC panels. The PSA backing eliminates the need for hook-and-loop systems, allowing fast disc changes without adhesive residue concerns. The 6-inch diameter fits standard DA sanders commonly found in automotive body shops and professional refinishing operations.
