3M 7010353440 Floor Surfacing Disc 7in 24 Grit

Product Description

The 3M 7010353440 is a precut floor surfacing disc designed for aggressive material removal on wood and hard-surface flooring. It features a sharp, fast-cutting synthetic mineral abrasive bonded to a tough, flexible backing that handles the flex and pressure demands of floor sanding work. At 7 inches in diameter with a 0.875-inch arbor hole and a 24-grit cut, this disc is suited for coarse stock removal, leveling, and prep work on hardwood, plank, or similar surfaces. Flooring contractors and finish carpenters are the primary installers of this consumable.

This disc is used in residential and light commercial flooring applications where a rotary or disc floor sander is in use. The 24-grit rating makes it appropriate for initial passes on rough, uneven, or heavily coated floors that require significant material removal before finer grits are applied. The precut format eliminates the need for field trimming, reducing setup time between disc changes on the job site.

Key Features

• Precut to 7 inches x 0.875 inches for direct drop-in fitment on compatible floor sanders
• 24-grit synthetic mineral abrasive provides fast, aggressive stock removal
• Tough, flexible paper or combination backing maintains conformity under sander pressure

Compatibility

Installation Notes

Installation of floor surfacing discs should be performed by a qualified flooring contractor or tradesperson familiar with rotary floor sanding equipment. Always power down and unplug the sander before changing discs. Inspect the backing pad for wear or damage before mounting a new disc, as a damaged pad can cause uneven cutting or disc failure. Follow the sander manufacturer's guidance on disc retention and operating speed to avoid disc separation during use.
