Merit Abrasives 08834173020 Psa Sanding Disc 10 in 80 Grit

Product Description

The MERIT ABRASIVES 08834173020 is a 10-inch PSA (pressure-sensitive adhesive) sanding disc built for stationary disc sanders used in grinding, stock removal, and surface preparation applications. The disc features an aluminum oxide abrasive at 80 grit, providing medium-grade cutting action suited for general material removal on wood, metal, and composites. A flexible cloth backing gives the disc durability and conformability under load. The black disc is part of the PSAAO series and weighs approximately 0.5 pounds. No vacuum holes are included in this configuration.

This disc is designed for use on stationary disc sanders in shop and production environments. The PSA mount allows for quick, tool-free disc changes directly onto a matching PSA platen. The 80-grit aluminum oxide abrasive is appropriate for initial shaping passes, edge work, and aggressive surface leveling where a finer finish is not the primary goal. It suits woodworking shops, fabrication facilities, and general maintenance operations where stationary disc sanders are part of the standard workflow.

Key Features

• 10-inch diameter fits standard stationary disc sander platens
• 80-grit aluminum oxide abrasive delivers medium-grade stock removal
• Flexible cloth backing provides durability and conformability under pressure

Compatibility

Designed for use with stationary disc sanders that accept 10-inch PSA-mount sanding discs on a solid (non-perforated) platen surface.

Installation Notes

Installation is performed by a shop technician or equipment operator. Power down and lock out the stationary disc sander before removing the old disc or applying the new one. Clean the platen surface of adhesive residue before applying the replacement disc to ensure full contact and even pressure across the abrasive face. Do not operate the sander if the disc shows signs of delamination or edge lift.
