Merit Abrasives 08834173164 Abrasive Disc 40 Grit 20 in

Product Description

The MERIT ABRASIVES 08834173164 is a 20-inch pressure-sensitive adhesive abrasive disc designed for stationary disc sanders. Built on a flexible cloth backing, this disc uses aluminum oxide abrasive at 40 grit for aggressive material removal on wood, metal, and composite surfaces. The PSA mount allows fast, tool-free installation directly onto a sanding platen. At 40 grit, this is a coarse-grade disc suited for stock removal, surface leveling, and weld preparation. It weighs 0.5 pounds and ships in a single-piece package.

This disc is intended for use on stationary disc sanders in woodworking shops, metal fabrication facilities, and general industrial finishing operations. The PSAAO series targets applications where rapid material removal is the priority before moving to finer finishing grits. The flexible cloth backing conforms well to sanding platens and holds up under sustained pressure during extended runs. The black disc color and no-vacuum-hole configuration make it straightforward to identify and mount without modification to the sander.

Designed for use with stationary disc sanders accepting 20-inch PSA abrasive discs. Verify platen diameter and PSA backing compatibility before installation.

Installation Notes

Power down and lock out the sander before removing the old disc or mounting a new one. Peel the release liner and align the disc carefully to the platen center before pressing firmly to seat the adhesive evenly. Avoid running the disc at speeds exceeding the manufacturer rating for the sander. Disc replacement is typically performed by shop technicians or maintenance personnel familiar with stationary abrasive equipment.
