Mirka 23-342-080 Gold 6 Inch PSA Linkroll Disc P80 is a 6-inch pressure-sensitive adhesive sanding disc roll built for fast material removal and surface prep across a wide range of shop and jobsite materials. This is a sanding disc designed for high-speed sanding and general surface preparation. Model Number: 23-342-080. If you need one abrasive that can handle body filler, paint removal, primer sanding, hardwood, softwood, plastics, and non-ferrous metals without loading up too quickly, this is the kind of disc you keep within reach.

The big story here is balance. P80 grit is coarse enough to do real work, but not so rough that it becomes a specialty-only disc. It is a practical choice for knocking down filler, removing old coatings, leveling rough areas, and starting the sanding sequence before moving to finer grits. On real prep work, that means less time fighting a dull disc and more time actually flattening the surface.

Mirka's Gold abrasive line is made for high-speed sanding, and that matters if you are running through multiple discs in a session. The semi-open grit binding and special stearate coating are there for a reason: they help reduce clogging and pill forming. In plain terms, the disc stays cleaner while sanding paint, primer, lacquer, filler, and similar materials that like to load up lesser abrasives. A cleaner disc cuts more consistently and usually lasts longer.

The 6-inch format fits the common size used in many sanding setups, while the PSA backing is meant for quick stick-on attachment and fast changeouts. That is useful when you are moving through prep stages or swapping discs often during refinishing, automotive work, woodworking, or paint correction prep. The Linkroll format also keeps the discs organized as a roll, which is a cleaner way to store and pull abrasives than dealing with loose stacks.

Material range is one of the strongest reasons to buy this Mirka sanding disc. Source data lists it for copper alloys, brass, bronze, non-ferrous metal, plaster, filler, fiberglass, synthetic materials, chipboard, veneer, plastics, primer, paint sanding, body filler, hardwood, soft or resinous wood, and lacquers. That makes it a solid fit for shops that bounce between substrates and do not want separate abrasives for every small task.

This is a good buy for automotive refinish work, cabinet and millwork prep, general woodworking, remodeling, and serious DIY surface prep. If your typical jobs involve stripping, leveling, shaping filler, or getting a surface ready for the next sanding stage, the Mirka 23-342-080 Gold 6 Inch PSA Linkroll Disc P80 makes sense. If you are already at the finish-sanding stage, you will want a finer grit. But for the front end of the sanding process, this is the right kind of aggressive.

Mirka 23-342-080 Gold 6 Inch PSA Linkroll Disc P80 is the kind of shop abrasive that earns its shelf space
