This is a PSA disc designed for sanding and material removal. Model Number 40-332-080. If you need a straightforward abrasive disc for knocking down material, cleaning up surfaces, or starting a sanding sequence with a more aggressive cut, this one is set up for that job with P80 grit aluminum oxide abrasive and a paper backing.\u003c\/p\u003e\n      \u003cp\u003eWhat matters here is the combination of grit, backing, and mounting style. P80 is a coarse grit, so it is better suited to early-stage sanding than finish work. That makes it a practical choice when you need to level a surface, remove old finish, or prep material before moving to finer grits. The aluminum oxide abrasive is a proven all-around abrasive material, and the coated construction gives you a familiar sanding feel for general shop and jobsite work.\u003c\/p\u003e\n      \u003cp\u003eThe pressure sensitive adhesive backing is the real convenience feature. A PSA disc is built for quick attachment to a compatible sanding pad, which helps cut downtime when you are changing worn discs. Compared with more involved attachment systems, PSA keeps the process simple and direct. On repetitive prep work, that matters.\u003c\/p\u003e\n      \u003cp\u003eThis Mirka disc uses a paper backing and a no-hole design. The paper backing helps keep the disc flexible enough for typical sanding tasks while still supporting the abrasive layer. The no-hole pattern means it is intended for setups that do not rely on a vacuum hole layout through the disc itself. That is important to check before ordering, especially if your current sander and pad are matched to a multi-hole dust extraction pattern.\u003c\/p\u003e\n      \u003cp\u003eThis pack includes 100 discs, which makes more sense for users who burn through abrasives regularly rather than someone buying a one-off replacement. For a shop, body work area, cabinet space, or general sanding station, buying in pack quantity reduces the hassle of constantly reordering consumables.\u003c\/p\u003e\n      \u003cp\u003eWho should buy it? The Mirka 40-332-080 PSA Disc makes the most sense for users who already run 5 inch PSA sanding setups and want a coarse grit disc for prep work. If your work starts with surface cleanup and material removal before finer sanding steps, this is the right kind of disc. If you need dust-extraction holes or a finer finish-ready grit, you will want a different configuration.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails
