This is a 5-inch PSA sanding disc designed for coarse sanding, stripping, and surface leveling. Model Number 40-332-060. If you are sanding lacquer, body filler, fiberglass-reinforced polyester, or weld seams, this is the kind of disc you reach for when the job starts rough and speed matters.\u003c\/p\u003e\n      \u003cp\u003eThe big story here is cut speed without giving up durability. Mirka positions the Coarse Cut line as an aggressive abrasive for heavy-duty sanding, and the P60 grit backs that up. On the job, that means faster knockdown on hard coatings and filler, less time trying to force a worn disc to keep working, and a cleaner path to your next grit.\u003c\/p\u003e\n      \u003cp\u003eMirka also calls out the specially reinforced backing and its Progressive Bond technology. In plain terms, that is about keeping the abrasive working longer under pressure. Cheaper coarse discs often start breaking down at the edges, especially when you hit metal edges, contours, or uneven repairs. Edge wear matters because once the edge starts failing, the scratch pattern gets inconsistent and the disc stops cutting the way it should.\u003c\/p\u003e\n      \u003cp\u003eThe semi-open coat design is there for a reason too. Coarse sanding creates a lot of debris fast, and loading is what kills productivity. A disc that resists clogging keeps cutting more consistently and saves you from peeling it off early just because it packed up. That is especially useful when you are working on fillers, coatings, and other materials that can gum up a lesser abrasive.\u003c\/p\u003e\n      \u003cp\u003eBecause this is a PSA disc, it is meant for sanders and backup pads that use pressure-sensitive adhesive mounting rather than hook and loop. That style gives you a firm, direct connection to the pad, which is a good match for more aggressive sanding where you want the disc to stay put. The 5-inch size keeps it in a common format for finish and prep work, especially in automotive, metalworking, and surface repair settings.\u003c\/p\u003e\n      \u003cp\u003eThis Mirka sanding disc makes the most sense for users doing real prep work, not light touch-up sanding. Body shops, metal fabricators, refinishers, and serious DIY users working on filler, coatings, or weld cleanup will get the most out of it. If your goal is fine finish sanding, this is not the disc for that. If your goal is to remove material quickly, keep the disc stable, and move the job forward, it is exactly the right kind of abrasive.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eBuilt to Remove Material Fast\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\/20260624669_1.jpg\" alt=\"Mirka 40-332-060 Coarse Cut PSA Disc 5 Inch abrasive face for coarse sanding and fast material removal during prep work on filler, coatings, and metal\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis disc is made for the rough stage of the job where speed matters more than finish.
