3M Company DISC5IN5PK120 Sanding Discs 5 in 120 Grit 5 Pack

Product Description

The 3M COMPANY DISC5IN5PK120 is a 5-pack of 5-inch, 120-grit sanding discs designed for use with random orbital sanders. Each disc features a hook-and-loop (Hookit) backing for fast, secure attachment and removal. The 120-grit abrasive makes these discs well suited for intermediate sanding tasks, light material removal, and surface prep across a wide range of coatings and substrates. The universal hole pattern allows compatibility with most random orbital sander pad configurations. These discs are a common shop consumable for trade professionals performing surface finishing work prior to painting, coating, or sealing.

These sanding discs are intended for all-purpose use on wood, metal, plastic, fiberglass, and painted surfaces. The 5-inch diameter and 120-grit rating make them appropriate for both rough smoothing and pre-finish prep work. Typical applications include surface conditioning before primer application, light paint feathering, and general finish sanding in residential and light commercial environments. The Hookit backing system allows quick disc changes during extended sanding sessions, reducing downtime.
