3M 7010296140 Floor Surfacing Disc 20 Grit 7 Inches

Product Description

The 3M 7010296140 is a precut floor surfacing disc engineered for aggressive material removal on hardwood and other flooring surfaces. Running at 20 grit, this disc is suited for coarse stock removal, leveling high spots, and initial surfacing passes where fast cutting action is required. It uses a sharp, fast-cutting synthetic mineral abrasive bonded to a tough, flexible paper or combination backing that resists tearing under load. Flooring contractors and hardwood floor finishers reach for discs in this grit range when opening up a floor surface or removing old finish before progressing to finer grits.

This disc is sized at 7 inches in diameter with a 5/16-inch arbor hole, making it compatible with drum and orbital floor sanders that accept this disc format. It is sold individually and is intended for professional flooring applications in residential and light commercial settings. The precut design eliminates the need to cut discs from a sheet, reducing prep time on the job.

Installation Notes

Floor surfacing discs are installed and serviced by flooring contractors and experienced tradespersons. Ensure the sander is powered off and unplugged before mounting or removing the disc. Inspect the backing pad for wear before each disc change, as a damaged pad can cause uneven cutting or disc failure. Always operate floor sanding equipment in accordance with the manufacturer guidelines and applicable jobsite safety requirements.
