3M 7100053408 Psa Disc 60 Grit 5 in Ceramic 100 Pack

Product Description

The 3M 7100053408 is a pressure-sensitive adhesive (PSA) abrasive disc rated at 60 grit with a ceramic aluminum oxide abrasive. Measuring 5 inches in diameter, each disc features an F-weight paper backing and a flexible construction that conforms to the work surface during use. The red disc is part of the 3M 763U series and is designed for stock removal and surface preparation tasks on wood, metal, and composites. Licensed tradespeople and finishing professionals rely on this disc for consistent cut rate and durability on production sanding lines and job-site applications. Each pack contains 100 discs.

This disc is suited for use with random orbital sanders in both residential and light commercial finishing environments. The PSA backing allows for quick disc changes without additional fasteners, reducing downtime during high-volume sanding operations. Typical applications include paint removal, bare wood shaping, weld seam blending, and substrate prep before priming. The medium-grade, 60-grit rating makes it appropriate for aggressive material removal where a finer finish grit will follow in subsequent steps.

Installation Notes

Disc installation and removal requires no tools — peel the PSA liner and press firmly onto a clean, dry sanding pad. Ensure the sander pad surface is free of adhesive residue before mounting a new disc to maintain even contact. Inspect the disc for tears or loading before each use and discard damaged discs. Follow applicable workplace safety guidelines including eye protection and dust collection when sanding metals, treated wood, or composite materials.
