3M 7010401386 Floor Surfacing Disc 120 Grit 7in

Product Description

The 3M 7010401386 is a precut floor surfacing disc designed for hardwood floor sanding and surface preparation work. Built with a sharp, fast-cutting synthetic mineral abrasive bonded to a tough, flexible paper or combination backing, this disc delivers consistent stock removal with a refined finish. At 7 inches in diameter and 0.3125 inches thick, the 120-grit abrasive is suited for intermediate to finish-stage sanding passes. Floor installers, hardwood flooring contractors, and surface prep professionals rely on this disc for production-level floor work where consistent cut rate and finish quality matter.

This disc is used in residential and light commercial floor sanding applications. It is sized and grit-rated for intermediate finishing passes on hardwood, engineered wood, and similar floor surfaces. The precut format eliminates on-site trimming, reducing setup time and material waste during large-area floor surfacing jobs. The flexible backing conforms to minor surface variation, helping maintain even scratch patterns across the floor field.
