3M 9x11 Professional Grade Sandpaper Set of 20 – 120 Grit

Overview

Whether you are refreshing a worn tabletop, smoothing cabinet doors, or prepping metal edges before finishing, the 3M 9x11 Professional Grade Sandpaper set is built to keep up with steady workflows. The larger 9x11 inch sheets cover more surface area per pass, helping you achieve consistent results across flat panels and wide surfaces. With a mid-fine 120 grit, this set is well suited for initial shaping, smoothing transitions, and readying a surface for paint or sealant without too aggressive a cut. The 20-sheet bundle provides a ready supply, so you can proceed from project to project without frequent restocking.

Key benefits at a glance

• The sandpaper is clog-resistant, helping maintain cutting efficiency as you work.
