This is a sanding disc designed for coarse sanding on fillers, lacquer, glass reinforced polyester, and welding seams. Model Number: 40-622-040. If your job starts with knocking material down fast instead of chasing a fine finish, this is the right kind of abrasive.\u003c\/p\u003e\n      \u003cp\u003eThe big story here is the \u003cstrong\u003eP40 grit\u003c\/strong\u003e. That coarse cut gives you the bite needed for early-stage sanding, where speed matters more than surface finish. It is a practical choice for shaping body filler, removing heavy coatings, and flattening rough areas before stepping through finer grits. Mirka also calls out minimal clogging, which matters when you are sanding materials that can load up a disc and kill cut speed early.\u003c\/p\u003e\n      \u003cp\u003eMirka pairs that aggressive grit with \u003cstrong\u003ealuminum oxide abrasive\u003c\/strong\u003e and a \u003cstrong\u003esemi-open coat\u003c\/strong\u003e construction. In plain terms, that means you get a durable abrasive surface that is made to keep cutting in demanding prep work. The \u003cstrong\u003especial reinforced F-weight paper backing\u003c\/strong\u003e is there for a reason too: coarse sanding puts more stress on the disc, especially around edges and curves, and stronger backing helps the disc hold together under that abuse.\u003c\/p\u003e\n      \u003cp\u003eThis disc uses a \u003cstrong\u003egrip attachment\u003c\/strong\u003e, which is the hook and loop style most users want for random orbit sanders and similar setups because disc swaps are fast. When you are moving from heavy stock removal to surface prep, that quick change saves time and keeps you working instead of peeling adhesives or fighting with worn-out discs. The \u003cstrong\u003eno-hole design\u003c\/strong\u003e is best suited to setups that do not require vacuum hole alignment in the disc.\u003c\/p\u003e\n      \u003cp\u003eMirka describes the Coarse Cut series as a durable product for all kinds of coarse sanding, with strong edge wear resistance. That matters when you are working around contours, edges, or metal transitions where weaker discs can tear and leave deeper, uneven scratch patterns. A tougher edge helps the abrasive stay consistent longer, which means fewer disc changes and more predictable prep work.\u003c\/p\u003e\n      \u003cp\u003eThe \u003cstrong\u003e6-inch diameter\u003c\/strong\u003e fits a common sander size used in automotive, metalworking, and general surface prep. This size gives you a good balance between coverage and control. It is large enough to move across panels or broad surfaces efficiently, but still manageable for more targeted sanding when you need to stay on a repair area or seam.\u003c\/p\u003e\n      \u003cp\u003eWho is this for? Pros and serious DIY users doing \u003cstrong\u003ebodywork, weld cleanup, filler shaping, coating removal, and rough surface prep\u003c\/strong\u003e. If you are looking for a finish-ready disc, this is not that. If you need a coarse sanding disc that gets through the ugly first stage quickly and holds up better doing it, this Mirka disc makes more 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 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\/20260623733_1.jpg\" alt=\"Mirka 40-622-040 Coarse Cut Grip Disc 6 inch sanding disc for coarse surface prep on filler, lacquer, and metalworking applications\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis Mirka 40-622-040 Coarse Cut Grip Disc is made for the first passes where you need the abrasive to stay sharp, cut hard, and hold together under pressure.\u003c\/p\u003e\n          \u003cul\u003e\n            \u003cli\u003eP40 grit is suited to heavy stock removal and rough prep work\u003c\/li\u003e\n            \u003cli\u003eReinforced F-weight paper backing helps the disc stand up to edge wear\u003c\/li\u003e\n            \u003cli\u003eAluminum oxide abrasive is a durable choice for repeated coarse sanding\u003c\/li\u003e\n          \u003c\/ul\u003e\n        \u003c\/div\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-whats-included\" class=\"acc\" open\u003e\n    \u003csummary\u003e\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"tnincluded-wrapper\"\u003e\n        \u003cul\u003e\n          \u003cli\u003e(25) Mirka 6 in.
