This is a \u003cstrong\u003e5-inch PSA sanding disc\u003c\/strong\u003e designed for fast stock removal and general sanding on soft and hard surfaces. For this variant, the model number is \u003cstrong\u003e24-314-080\u003c\/strong\u003e, which corresponds to \u003cstrong\u003e80 grit\u003c\/strong\u003e. If you are doing bodywork, paint prep, woodworking, or general finish removal, this is the kind of abrasive that makes the first sanding step go quicker.\u003c\/p\u003e\n      \u003cp\u003eWhat matters here is not just that it is 80 grit, but how it is built. Mirka uses a blend of \u003cstrong\u003eceramic and aluminum oxide grains\u003c\/strong\u003e, which gives the disc a strong initial bite and helps it keep cutting as the job goes on. On rough prep work, that means less time leaning on the sander and fewer early disc changes when you are trying to knock down material efficiently.\u003c\/p\u003e\n      \u003cp\u003eThe \u003cstrong\u003eflexible paper backing\u003c\/strong\u003e is a big part of why the Iridium line works across different materials and tasks. A stiff abrasive can feel fine on a flat panel but become less forgiving as soon as the surface changes. A more flexible backing helps the disc stay useful across broader sanding work, especially when you move between surface leveling, edge work, and prep before finer grits.\u003c\/p\u003e\n      \u003cp\u003eMirka also calls out a \u003cstrong\u003eprecision coating\u003c\/strong\u003e that helps prevent clogging and reduce pilling. In plain terms, that matters because loaded paper stops cutting and starts wasting motion. An abrasive that resists buildup stays productive longer, especially when sanding coatings, fillers, or mixed surfaces where dust can pack the face of the disc fast.\u003c\/p\u003e\n      \u003cp\u003eBecause this is a \u003cstrong\u003ePSA disc\u003c\/strong\u003e, it is intended for sanding setups that use pressure-sensitive adhesive attachment rather than hook-and-loop. That gives you a firm, flat hold on the pad, which is useful when you want a consistent scratch pattern and solid contact during aggressive sanding passes. Just make sure your backing pad is set up for PSA discs before you order.\u003c\/p\u003e\n      \u003cp\u003eThe 5-inch, or \u003cstrong\u003e125 mm\u003c\/strong\u003e, size is a common format for finishing and prep sanders, so this disc fits right into a lot of everyday shop and jobsite sanding routines. It is a good choice for pros who burn through abrasives regularly and want a paper abrasive that cuts fast, stays usable, and works across multiple materials instead of being limited to one narrow task.\u003c\/p\u003e\n      \u003cp\u003eIf you are the buyer who cares more about how quickly an abrasive cuts, how long it stays useful, and how cleanly it works through surface prep than about flashy packaging, this is the right kind of product. The Mirka IRIDIUM 5\" PSA makes the most sense for body shops, cabinet shops, finish prep, and anyone who needs a dependable \u003cstrong\u003esanding disc\u003c\/strong\u003e for repeatable material removal.\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 for Faster Surface Prep\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\/20260623386_1.jpg\" alt=\"Mirka IRIDIUM 5 inch PSA sanding disc roll for surface preparation and material removal in shop sanding work\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis grit range is where a lot of real prep work starts.
