3M 7010328799 Floor Surfacing Disc 50 Grit 7 Inches

Product Description

The 3M 7010328799 is a precut floor surfacing disc engineered for aggressive material removal on wood, concrete, and similar floor substrates. Built with a sharp, fast-cutting synthetic mineral abrasive bonded to a tough, flexible combination backing, this disc is designed to cut quickly while maintaining consistent performance across the life of the abrasive. At 50 grit, it handles coarse stock removal and surface preparation tasks common in flooring installation and restoration work. Licensed flooring contractors and abrasives technicians are the primary installers and end users.

This disc is suited for residential and light commercial floor surfacing applications where a coarse-cut abrasive is needed to remove old coatings, level uneven surfaces, or prep hardwood and similar materials for finishing. The precut format reduces setup time on floor-mounted disc sanders and similar rotary surfacing equipment. At 7 inches in diameter, it fits standard floor disc sander arbors used across the flooring trade.

Installation Notes

Floor surfacing discs of this type are installed and operated by licensed flooring contractors or experienced trade professionals.

Inspect the backing pad for damage before each disc change, as a worn pad can cause uneven abrasion or disc failure.
