3M 7010328797 Floor Surfacing Disc 80 Grit 7x0.875 in

Product Description

The 3M 7010328797 is an 80-grit floor surfacing disc designed for drum and rotary floor sanders used in hardwood floor refinishing and surface preparation. The disc features a sharp, fast-cutting synthetic mineral abrasive bonded to a tough, flexible backing that handles the demands of production floor sanding. At 7 inches in diameter with a 0.875-inch arbor hole, the disc is precut and ready to mount. Licensed flooring installers, finish carpenters, and professional floor refinishers are the primary users of this consumable abrasive.

This disc is suited for residential and light commercial floor sanding applications. It performs well on hardwood, softwood, and wood subfloor surfaces where consistent stock removal and finish prep are required. The 80-grit designation places it in the medium-cut range, making it appropriate for initial smoothing passes, paint or finish removal, and leveling boards prior to finer finish grits. The precut format eliminates on-site trimming and speeds changeover between passes.

Key Features

• 80-grit synthetic mineral abrasive for fast, consistent stock removal
• Precut disc format reduces setup time and eliminates field trimming
• Tough, flexible paper or combination backing withstands flex and heat generated during floor sanding
• 7-inch diameter with 0.875-inch arbor hole fits standard floor sanding equipment

Installation Notes

Installation is performed by flooring professionals or licensed contractors. Ensure the sander drum is fully stopped and the machine is unplugged or powered down before mounting or removing the disc.
