Merit Abrasives 08834173167 Psa Disc 80 Grit 20 in

Product Description

The MERIT ABRASIVES 08834173167 is a pressure-sensitive adhesive (PSA) abrasive disc designed for stationary disc sanders. It measures 20 inches in diameter and uses 80-grit aluminum oxide as the abrasive material, making it suitable for medium-stock removal on a range of workpiece materials. The cloth backing provides flexibility and durability under sustained sanding pressure. This disc mounts directly to a sander platen via its PSA backing, eliminating the need for separate fasteners or clamps. It is commonly installed and used by woodworkers, metal fabricators, and trade professionals performing surface preparation, shaping, or blending operations.

This disc is intended for use on stationary disc sanders in shop and production environments. The 80-grit rating positions it for general-purpose material removal and surface leveling before finishing passes. Its flexible cloth backing conforms slightly to the platen surface, promoting even contact across the full 20-inch face. No vacuum holes are included, so it is suited to standard solid-platen disc sander setups rather than dust-extraction platen configurations.

Installation Notes

Power down and lock out the sander before removing the old disc or applying a new one. Clean the platen surface of adhesive residue and debris before mounting to ensure full PSA contact across the disc face. Peel the release liner and align the disc carefully to the platen center before pressing firmly from the center outward to eliminate air pockets. Inspect the disc for lifting edges before resuming operation.
