This is a sanding disc designed for finishing and heavy stock removal. Model Number: \u003cstrong\u003e23-320-080\u003c\/strong\u003e. If you need a reliable abrasive for flattening, stripping, or getting a surface ready for the next grit, this is the kind of consumable that earns its keep.\u003c\/p\u003e\n      \u003cp\u003eWhat matters here is how the abrasive performs under real use. The P80 grit is coarse enough to move material at a useful pace without jumping straight into overly aggressive grinding. Mirka calls out this disc for finishing and heavy stock removal, which makes it a solid choice for early sanding stages, surface correction, and prep work where speed matters but you still want a consistent scratch pattern you can refine later.\u003c\/p\u003e\n      \u003cp\u003eThe disc uses durable aluminum oxide grain, and that matters because sharp grain cuts faster and stays productive longer. Mirka also specifies high-strength resin bonding for better grain support, plus a proprietary backing that is stronger than traditional backing used by competing brands. In plain terms, that means the disc is built to hold together under pressure instead of giving up when the work gets hot or dusty.\u003c\/p\u003e\n      \u003cp\u003eFor cleaner sanding, this disc uses an 8-hole vacuum pattern. Combined with the special stearate coating and semi-open coat design, the setup is aimed at resisting clogging and loading while helping dust move away from the work surface. That is a big deal on paint prep, filler work, and sanding tasks that normally pack abrasive discs full before the job is done.\u003c\/p\u003e\n      \u003cp\u003eThe pressure-sensitive adhesive backing keeps attachment simple for PSA-compatible sanding pads. Once installed, you get a firm hold that helps the disc stay flat and cut evenly. The 5-inch diameter is a common size for sanding applications, and Mirka also lists fitment with DeWalt DC421 and DC423, plus 5-inch Ryobi and Bosch 3107 and 3725 tools.\u003c\/p\u003e\n      \u003cp\u003eThis pack is best suited for body shop work, woodworking, metal prep, plastic surface prep, and general shop sanding where you go through discs regularly and need box quantity on hand. If you are a pro who wants a known abrasive that cuts cleanly and resists loading, or a serious DIY user doing refinish or prep work, this Mirka sanding disc 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\u003eBuilt to Keep Cutting\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\/20260624875_1.jpg\" alt=\"Mirka Gold 5 Inch 8 Hole PSA Vacuum Disc P80 100 Pieces box and sanding disc for wood, metal, and plastic surface preparation in a shop setting\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis sanding disc is meant for users who care more about cut rate and consistency than bargain-bin abrasives.
