This is a sanding disc designed for coarse sanding on lacquer, putty, glass reinforced polyester, and welding seams. Model Number: 40-341-080. If you need to knock down material quickly before moving to finer grits, this is the kind of abrasive that earns its keep early in the sanding process.\u003c\/p\u003e\n      \u003cp\u003eThe big story here is the P80 grit. That puts this disc squarely in the heavy-cut category, where speed matters more than finish quality. It is intended for shaping, leveling, and cleaning up surfaces that still need more refinement afterward. For bodywork, fabrication prep, or rough surface correction, that coarse cut helps remove material without wasting time.\u003c\/p\u003e\n      \u003cp\u003eMirka also calls out why this abrasive is meant to last longer under hard use. The disc uses a coated construction with specially reinforced backing material and Mirka Progressive Bond technology. The practical benefit is better edge strength during aggressive sanding, especially around metal edges where cheaper discs tend to fray, tear, or leave inconsistent scratch marks once the edge breaks down.\u003c\/p\u003e\n      \u003cp\u003eAnother useful detail is that the disc is described as having minimal clogging and flexibility on rounded surfaces. That matters when you are working on contoured parts or uneven repairs where a stiff, loading-prone abrasive can slow you down fast. For users sanding filler, coatings, or composite surfaces, less clogging usually means more consistent cutting before the disc needs to be changed out.\u003c\/p\u003e\n      \u003cp\u003eThis Mirka sanding disc uses PSA backing, which means pressure sensitive adhesive attachment. That setup is best for users who want a firm bond between the disc and the sanding pad. It is listed as compatible with an angle grinder, so it fits applications where an aggressive abrasive disc is being used on powered equipment for fast removal work.\u003c\/p\u003e\n      \u003cp\u003eWho should buy it? This is a good fit for automotive refinish work, metal prep, fiberglass repair, and general coarse sanding where surface removal comes first and finish quality comes later. If you are doing rough prep on putty, lacquer, reinforced polyester, or weld seams, the Mirka 40-341-080 Coarse Cut PSA Disc, 6\" makes sense. If you are looking for a finish-ready scratch pattern, you will want to step down to a finer grit after this stage.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eMade for Fast Material Removal\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\/20260623412_1.jpg\" alt=\"Mirka 40-341-080 Coarse Cut PSA Disc 6 inch P80 sanding disc for coarse sanding and surface prep on metal, filler, and composite materials\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis disc is built for the rough stage of the job where you need to remove material quickly and keep moving.
