This is a sanding disc designed for heavy stock removal on paint, putty, primer, wood, steel, mineral materials, and plastic. Model Number 24-6MH-040. If you need to strip a surface, level filler, or cut through rough material before moving into refinement, this is the coarse grit you reach for.\u003c\/p\u003e\n      \u003cp\u003eThe big story here is speed without throwing away disc life. Mirka uses a ceramic alumina and aluminum oxide grain mix that gives the disc an aggressive initial cut, but the grains are also meant to stay sharper longer than basic paper abrasives. On the job, that means less time leaning on the sander waiting for the disc to do something, and fewer swaps when you're working through broad prep work.\u003c\/p\u003e\n      \u003cp\u003eThe 40-grit rating puts this squarely in rough-prep territory. That makes it a solid fit for taking down body filler, removing coatings, flattening rough wood, and getting stubborn surfaces ready for the next sanding step. It is not a finishing disc, and that is the point. This grit is here to move material fast and get you to the next stage sooner.\u003c\/p\u003e\n      \u003cp\u003eMirka also built this disc around dust control. The multi-hole pattern is there to improve extraction across the face of the disc, and the dust-repellent coating helps reduce clogging and pilling. In real use, that matters because loaded discs cut slower, run hotter, and leave a more inconsistent scratch pattern. Better dust flow helps the abrasive stay open and useful longer.\u003c\/p\u003e\n      \u003cp\u003eThe backing is flexible paper with hook and loop attachment, which makes changes quick and keeps the disc easy to work with on powered sanding setups that use 6-inch round discs. That flexible backing also helps the abrasive stay planted across curved or slightly uneven surfaces instead of feeling overly stiff and skittery.\u003c\/p\u003e\n      \u003cp\u003eThis 50-pack makes sense for shops and users who burn through coarse abrasive regularly. If you're doing collision repair prep, paint removal, filler shaping, wood surface leveling, or general sanding where speed matters more than finish quality, this is the right kind of disc to keep on hand in volume. Pros will appreciate the cut rate and dust control. Serious DIY users will appreciate not wasting time with bargain discs that clog too fast.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eCut Fast on Rough 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\/20260624048_5.jpg\" alt=\"Mirka Iridium Premium Sandpaper Ø 6-Inch Hook \u0026amp; Loop, Grit 40 installed on a random orbital sander for sanding a wood panel in a workshop setting\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eWhen the job starts with rough stock removal, a coarse disc needs to bite hard and keep working.
