Value Collection 809775-07821 Psa Disc 4 in 80 Grit

Product Description

The VALUE COLLECTION 809775-07821 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface grinding, blending, and finishing applications. It measures 4 inches in diameter and uses 80-grit aluminum oxide abrasive, placing it in the medium grade range. The disc features an X-weight cloth backing, which provides durability and flexibility during aggressive material removal. It mounts via a PSA interface, adhering directly to compatible backup pads. Machinists, metalworkers, woodworkers, and fabricators typically use this disc with random orbital or disc sanders on bench-top or portable equipment.

This disc suits a range of surface preparation tasks including rust removal, weld blending, paint stripping, and stock removal on metal, wood, and composites. The 80-grit rating makes it appropriate for initial stock removal or preparation work before moving to finer grits. The flexible cloth backing allows the disc to conform slightly to curved or irregular workpiece surfaces, improving contact and cut consistency. No vacuum holes are present, so it is intended for use on solid backup pads without dust extraction ports.

Key Features

• 4-inch diameter PSA disc - attaches directly to adhesive-compatible backup pads
• 80-grit aluminum oxide abrasive for medium-grade stock removal and surface prep
• X-weight cloth backing provides strength and flexibility for demanding applications
• Flexible construction allows conformance to slightly curved or irregular surfaces
• No vacuum holes - designed for use with solid, non-perforated backup pads

Compatibility

Designed as a standard PSA-mount replacement disc for 4-inch backup pads used with disc sanders, random orbital sanders, and angle grinders equipped with adhesive-backed pad systems.

Installation Notes

Installation is performed by trade workers, fabricators, or operators using disc or orbital sanding equipment. Before mounting, ensure the backup pad surface is clean and free of adhesive residue from previous discs to achieve full contact and secure adhesion. Power down and unplug or lock out the tool before changing discs. Do not exceed the maximum RPM rating of your backup pad or sanding tool.
