Value Collection 809775-08373 Psa Disc 18 in 40 Grit

Product Description

The VALUE COLLECTION 809775-08373 is an 18-inch pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal across a range of surfaces. It runs a 40-grit aluminum oxide abrasive on an X-weight cloth backing, making it a coarse-grade option built for durability under heavy stock removal. The PSA backing mounts directly to compatible foam or rubber backup pads without fasteners or hardware. At 0.88 pounds per disc, the construction is robust enough for sustained use on stationary disc sanders and large portable grinding setups. No vacuum holes are included, so this disc suits solid backup pads.

This disc is rated for use on ferrous and non-ferrous metals, plastics, and wood, making it a versatile choice for fabrication shops, metalworking operations, and woodworking facilities. The coarse 40-grit cut is best suited for initial shaping, weld blending, rust removal, and rapid stock reduction rather than finish work. The flexible cloth backing conforms slightly to irregular surfaces, which helps maintain consistent contact during use. It is sold and packaged as a single disc, so quantity ordering should be planned accordingly.

Compatibility

Designed for use with 18-inch PSA-compatible foam or rubber backup pads on stationary disc sanders and large-format grinding equipment. No specific machine model compatibility was provided by the manufacturer for this part number.

Installation Notes

PSA discs are installed by peeling the liner from the adhesive backing and pressing the disc firmly onto a clean, dry backup pad surface. Ensure the backup pad is free of debris, adhesive residue, and damage before mounting to achieve full contact and even wear. Disengage power and allow the machine to come to a complete stop before changing discs. Inspect the disc for tears or delamination before each use and discard any disc showing visible damage.
