This is a sanding disc designed for stock removal, surface prep, and general finishing work on wood, fillers, coatings, and plastics. Model Number: 20-314-080. If you need a coarse disc that cuts fast without jumping to a specialty abrasive, this is the kind of everyday shop consumable that earns its keep.\u003c\/p\u003e\n    \u003cp\u003eWhat matters here is the balance between cost and usable performance. Mirka positions the Basecut line as an economical, high-efficiency abrasive, and the spec sheet backs that up with aluminum oxide grain, semi-open coating, and resin over resin bonding. In practical terms, that means the disc starts cutting aggressively and holds up well through repeated passes instead of falling off too early when you are leveling body filler, knocking down old paint, or opening up a wood surface before finer grits take over.\u003c\/p\u003e\n    \u003cp\u003eThe 5 inch diameter fits a common orbital sander size, so this format makes sense for a lot of shops already set up around standard 5 inch backup pads. The PSA adhesive attachment is the big functional detail. If you prefer a stick-on disc rather than hook and loop, PSA gives you a firm bond to the pad, which helps keep the disc planted during sanding. That can be especially useful when you want stable contact and a clean, even scratch pattern on flat work.\u003c\/p\u003e\n    \u003cp\u003eThis disc uses a no-hole pattern, so it is best suited for applications where you are not relying on pad-through dust extraction from a matching hole layout. That is worth knowing before you buy. If your setup is built around perforated discs for dust collection, you will want to match that system carefully. If you are focused more on straightforward sanding performance and pad adhesion, this no-hole PSA format keeps things simple.\u003c\/p\u003e\n    \u003cp\u003eThe material package is aimed at broad shop use. Source data lists it for lacquers, paint removal, plaster, putty, plastics, wood, glass fibre, chipboard, veneer, solid surface, body filler, hardwood, and soft or resinous woods. That range is why these discs make sense in automotive refinish bays, cabinet and millwork shops, and marine maintenance work. One roll can cover rough shaping, coating removal, and prep sanding across several different materials.\u003c\/p\u003e\n    \u003cp\u003eThe Linkroll format is also practical. Instead of loose discs sliding around in a drawer, the roll keeps the 100-disc pack organized and easier to stage at the bench. For anyone going through abrasive regularly, that means less wasted time digging for the right grit and less chance of edges getting bent before the disc ever hits the tool.\u003c\/p\u003e\n    \u003cp\u003eWho should buy this? Anyone running a 5 inch orbital sander with a PSA pad who needs a coarse 80 grit disc for productive material removal. It is a solid fit for body shops, woodworkers doing surface prep, marine finishing crews, and serious DIY users who want a known brand abrasive in a bulk count. If your work starts with cutting through coatings, leveling filler, or flattening wood before stepping down to finer grits, this Mirka pack makes sense.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n  \u003csummary\u003e\u003ch2\u003eCoarse Cut for Prep Work\u003c\/h2\u003e\u003c\/summary\u003e\n  \u003cdiv class=\"acc-body\"\u003e\n    \u003cdiv class=\"row\"\u003e\n      \u003cdiv class=\"img\"\u003e\n        \u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/20260624061_3.jpg\" alt=\"Mirka Basecut 5 in 80 Grit PSA sanding disc used for orbital sander prep work on wood filler paint and surface refinishing tasks\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eThis grit is meant to move material, not just clean up a surface.
