This is a sanding disc designed for stock removal, surface prep, and dust-extracted sanding across wood, filler, paint, plastics, lacquers, and non-ferrous metal. If you need an extra coarse disc that removes material quickly without giving up disc life, this is the right end of the grit range to look at.\u003c\/p\u003e\n      \u003cp\u003eThe big selling point here is Mirka's \u003cstrong\u003eMultifit universal hole configuration\u003c\/strong\u003e. On the job, that matters because it helps the disc work with many 5 inch dust-free orbital sanding tools and backing pads instead of locking you into one exact hole pattern. Better dust flow means the abrasive stays cleaner, cuts more consistently, and spends less time skating over packed dust. That is especially useful when you're stripping paint, flattening body filler, or cutting down rough wood where loading can kill performance fast.\u003c\/p\u003e\n      \u003cp\u003eThe abrasive itself uses \u003cstrong\u003ealuminum oxide grain\u003c\/strong\u003e with \u003cstrong\u003eresin over resin bonding\u003c\/strong\u003e and a \u003cstrong\u003esemi-open coating\u003c\/strong\u003e. In plain terms, that combination is about balancing cut speed and durability. Aluminum oxide is a proven grain for general-purpose sanding, the resin bond helps support the grain under pressure, and the semi-open coating helps reduce clogging when you're working materials like filler, primer, paint, lacquer, or resinous wood. For a coarse P40 disc, that matters because these jobs are usually aggressive and hard on paper.\u003c\/p\u003e\n      \u003cp\u003eThe \u003cstrong\u003e5 inch diameter\u003c\/strong\u003e and \u003cstrong\u003egrip-style hook and loop attachment\u003c\/strong\u003e make these discs a straightforward fit for common random orbital sanders and dust-extracted finish sanders that use 125 millimeter pads. Hook and loop backing keeps disc changes quick, which is exactly what you want when moving through prep stages or swapping out a worn disc mid-job. Less downtime at the bench means more time actually sanding.\u003c\/p\u003e\n      \u003cp\u003eThis specific version is the \u003cstrong\u003eP40 grit\u003c\/strong\u003e, which puts it firmly in the heavy-removal category. It is the grit you reach for when you need to strip coatings, level filler, break down rough surfaces, or remove stock before refining with finer discs. It is not the finish-pass disc. It is the get-the-surface-under-control disc. For bodywork, wood prep, and renovation work, that first step is often where the time gets lost, so using the right coarse abrasive matters.\u003c\/p\u003e\n      \u003cp\u003eMirka lists this abrasive for a broad material range including \u003cstrong\u003ecopper alloys, brass, bronze, non-ferrous metal, plaster, filler, glass fiber, synthetic materials, chipboard, veneer, plastics, primer, paint, hardwood, softwood, resinous wood, and lacquers\u003c\/strong\u003e. That wide material coverage makes this a practical shop staple if you bounce between automotive refinishing, cabinet work, repair work, and general surface prep. You are not buying a one-material specialty disc here. You are buying a general-purpose coarse abrasive that can move around the shop with you.\u003c\/p\u003e\n      \u003cp\u003eThis pack includes \u003cstrong\u003e50 discs\u003c\/strong\u003e, which makes more sense for working users than a small trial pack. If you burn through abrasives doing panel prep, filler shaping, paint removal, or rough sanding, a 50-count box keeps you working and cuts down on reorders. For shops that rely on consistent consumables, that is a simple but real advantage.\u003c\/p\u003e\n      \u003cp\u003eWho should buy this? Pros and serious DIY users running a \u003cstrong\u003e5 inch orbital sander\u003c\/strong\u003e for automotive prep, woodworking, remodeling, paint removal, and filler sanding. If your work starts with rough surfaces and you want fast cut, universal pad compatibility, and better dust extraction than a basic solid disc, the Mirka GOLD Multifit 5 in Grip Sanding Discs are an easy pick. If you are already at finish sanding stages, step to a finer grit in the same line instead.\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\u003eBetter Dust Flow Means More Useful Cutting\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\/20260623931_4.jpg\" alt=\"Mirka GOLD Multifit 5 in Grip Sanding Discs installed on a dust-extracted orbital sander during automotive surface preparation on a painted panel\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eA coarse sanding disc works best when dust can move away from the abrasive instead of packing into it.
