The Mirka GOLD 5" PSA Linkroll in P80 grit is a pressure-sensitive adhesive sanding disc for high-speed sanding across multiple materials. This is a sanding disc designed for fast stock removal, surface prep, and general abrasive work. Model Number: 23-314-080. If you need an abrasive that cuts aggressively but still holds up under production use, this is the kind of disc that makes sense.

What matters here is not just that it is an 80-grit disc, but how it is built. The aluminum oxide abrasive is a proven choice for everyday sanding because it balances cutting speed, finish quality, and durability. On the job that means this disc is a solid fit when you are knocking down filler, leveling primer, stripping rough surfaces, or getting wood and metal ready for the next step.

Mirka uses a semi-open coating and special stearate treatment on the Gold line to help prevent clogging and pill forming. That matters when you are sanding finishes, fillers, coatings, or softer materials that can load a disc fast. A clogged disc stops cutting, runs hotter, and wastes time. This design helps the abrasive stay useful longer and keeps the scratch pattern more consistent.

The resin-over-resin bonding adds durability for high-speed sanding, especially when the work is repetitive or production-driven. Combined with the C-paper backing and PE foam backing construction listed in the source data, the disc is built to handle real sanding pressure without feeling like a cheap consumable. That is the difference between a disc that gets through a task cleanly and one that starts falling off in performance halfway through.

The PSA format is also a practical choice for users who want quick disc changes and a secure stick-on connection to the backup pad. For shops and tradespeople who already run PSA sanding setups, the Mirka GOLD 5" PSA Linkroll keeps the workflow simple. The linkroll format is useful in a working environment because it is made for dispensing discs efficiently instead of dealing with loose stacks all over the bench.

Mirka positions this abrasive for automotive refinishing, woodworking, metalworking, marine work, and vehicle manufacturing, and that lines up with where a P80 disc earns its keep. This is not your finishing grit. It is the step for heavier prep, cleanup, and shaping work before you refine the surface further. If you are a body shop tech, cabinet guy, fabrication shop, or serious DIY user who burns through abrasives and notices when discs stop cutting too soon, this one is built for you.
