Merit Abrasives 08834172051 Psa Sanding Disc 6 in 120 Grit

Product Description

The MERIT ABRASIVES 08834172051 is a 6-inch PSA (pressure-sensitive adhesive) sanding disc designed for surface preparation, finishing, and material removal tasks. Built with an aluminum oxide abrasive on a flexible cloth backing, this disc delivers consistent cut and durability across metal, wood, composites, and similar substrates. The 120-grit fine grade makes it well suited for intermediate finishing passes where controlled material removal and surface smoothing are the priority. The PSA mount allows for fast, tool-free disc changes on compatible random-orbit and disc sanders, reducing downtime in production or job-site environments.

This disc is commonly used by metal fabricators, HVAC sheet metal workers, woodworkers, and general maintenance trades. The flexible cloth backing conforms to slightly contoured surfaces, making it effective on both flat panels and mild curves. The fine 120 grit is appropriate for preparing surfaces before priming, sealing, or bonding. No vacuum holes are present, so it is intended for use on sanders without dust-extraction hole patterns at the pad.

Compatibility

Designed as an OEM-style replacement or consumable for use with 6-inch PSA-style random-orbit and disc sanders equipped with solid, non-perforated backing pads.

Installation Notes

PSA discs are installed by a wide range of trades as a consumable abrasive. Before mounting, ensure the sander backing pad is clean and free of adhesive residue from previous discs, as contamination reduces bond strength and can cause disc separation during use. Peel the release liner and align the disc squarely to the pad before pressing firmly into contact. Inspect the disc for lifting edges before operating the tool at full speed.
