Merit Abrasives 08834172050 Psa Disc 6 in 100 Grit

Product Description

The MERIT ABRASIVES 08834172050 is a 6-inch pressure-sensitive adhesive (PSA) abrasive disc designed for sanding and surface preparation tasks. It uses aluminum oxide as the abrasive material, rated at 100 grit for fine-grade stock removal and finishing. The disc features a flexible cloth backing that conforms to contoured surfaces and holds up under moderate heat and friction. At 0.01 pounds, it is a lightweight single-disc unit suited for use on random orbital and disc sanders equipped with a PSA platen. Metalworkers, auto body technicians, woodworkers, and general fabrication shops are the primary users of this consumable.

This disc is well suited for fine surface finishing on metal, wood, composites, and painted surfaces. The 100-grit aluminum oxide abrasive cuts consistently across flat and slightly curved work surfaces. The cloth backing adds flexibility, making it useful on contoured panels or shaped stock where a rigid disc would lose contact. The PSA adhesive mount allows fast disc changes on compatible sanders without additional fasteners or hook-and-loop hardware. It is sold as a single disc per package.

Installation Notes

Power down and unplug the sander before removing or mounting a PSA disc. Clean the platen surface of any adhesive residue before applying the new disc to ensure full contact and secure adhesion. Align the disc centered on the platen before pressing firmly to activate the adhesive. Since this disc has no vacuum holes, verify the tool platen is also a solid non-perforated type to maintain proper backing support.
