3M 7100111129 Abrasive Disc Roll 5 Inch P180 Grit

Product Description

The 3M 7100111129 is a Stikita Paper Disc Roll featuring open-coat aluminum oxide abrasive on a lightweight A-weight paper backing. Sold in roll form, each disc uses a pressure-sensitive adhesive backing for fast attachment and clean removal without disc liners. The P180 grit rating makes this disc well suited for lightweight sanding and finish-prep work on a range of surfaces. At 5 inches in diameter, the discs fit standard 5-inch random orbital and disc sanders commonly used in woodworking, automotive, and light metalworking applications. Trade finishers and production sanding professionals install these discs as part of high-volume sanding operations.

This disc roll is intended for lightweight sanding and finishing tasks in both shop and production environments. The open-coat construction reduces loading by allowing dust and debris to clear the abrasive surface, maintaining cut rate and extending disc life. The roll format eliminates the need to handle individual liners, which speeds up disc changes on busy job sites or in production finishing lines. Applications include wood finishing, surface prep, paint scuffing, and light material removal on ferrous and non-ferrous substrates.

Installation Notes

These discs are installed by trade finishers, woodworkers, and production sanding operators without special tools. Ensure the sander backing pad is clean and free of debris before applying the adhesive disc to promote full contact and prevent premature release. Do not exceed the maximum RPM rating of the sander in use. Remove the disc promptly after use to prevent adhesive transfer to the backing pad.
