This is a sanding disc designed for aggressive wood sanding and surface prep. Model Number UL-6MF-040. If you're flattening rough boards, knocking down mill marks, cleaning up resinous softwood, or getting hardwood ready for the next grit, this pack is aimed at woodworkers, cabinet shops, flooring crews, and serious DIY users who need a disc that cuts hard without giving up too early.\u003c\/p\u003e\n      \u003cp\u003eWhat matters here is not just that these are 40 grit discs, but how they are built to behave in actual sanding. A coarse grit needs to stay open and keep cutting, otherwise it just heats up, loads with dust, and starts skating across the surface. Mirka calls out fast and even material removal, and the Multifit dust-channel pattern is there for a reason: it helps clear sanding debris while you work. That means more consistent cutting and less time peeling off clogged discs before they should be done.\u003c\/p\u003e\n      \u003cp\u003eThe backing matters too. These discs use latex paper with D-paper and C-paper construction, which gives them a useful mix of flexibility and durability. In plain terms, they have enough strength to handle harder sanding passes, but they are not so stiff that they fight you on edges, contours, or uneven wood. For furniture parts, cabinet panels, flooring pieces, and general woodworking surfaces, that balance makes a difference. You want the abrasive to stay planted and cut cleanly, not crack at the edge or fold up after a few passes.\u003c\/p\u003e\n      \u003cp\u003eMirka also positions this Ultimax Ligno abrasive specifically for wood. That makes sense given the stated use on softwood and hardwood, plus the emphasis on resinous woods and clean cutting performance. If you sand a lot of pine, fir, or similar material that tends to gum up cheaper paper, a disc designed to resist clogging is worth paying attention to. The goal is simple: keep the abrasive face open longer so the disc keeps removing material instead of rubbing and burning time.\u003c\/p\u003e\n      \u003cp\u003eAttachment is straightforward. These are 6-inch hook and loop sanding discs with a Grip \/ Multifit style backing for quick changes on compatible orbital sanders. That is a practical benefit on real jobs, especially when you're stepping through a sanding sequence or burning through coarse discs during heavy prep. Pull one off, press the next one on, and get back to work. No adhesive mess, no wasted setup.\u003c\/p\u003e\n      \u003cp\u003ePack size is another real-world advantage. With 50 discs in the box, this is not a small sampler pack. It is enough quantity for production work, repeated shop use, or a larger project where you know coarse sanding will eat through abrasives. That makes this Mirka sanding disc pack a better fit for users who sand regularly, not someone looking for one disc for a single touch-up.\u003c\/p\u003e\n      \u003cp\u003eWho should buy this? Anyone doing wood surface prep where fast removal matters more than finish-ready scratch pattern. That includes cabinetmakers leveling panels, carpenters cleaning up rough stock, flooring installers prepping boards, furniture builders shaping parts, and remodelers dealing with wood refinishing prep. If your next step is a finer grit and your first job is to remove material efficiently, the Mirka Ultimax Ligno 6-Inch Grit 40 Hook and Loop Sanding Discs make sense. If you need final finish sanding, go finer. If you need a disc that gets the rough work done first, this is the right kind of abrasive.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-at-a-glance\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eAt a Glance\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"stats-grid\"\u003e\n        \u003cdiv\u003e\n          \u003cdiv class=\"stat-value\"\u003e6 in\u003c\/div\u003e\n          \u003cdiv class=\"stat-label\"\u003eDisc Diameter\u003c\/div\u003e\n        \u003c\/div\u003e\n        \u003cdiv\u003e\n          \u003cdiv class=\"stat-value\"\u003e40\u003c\/div\u003e\n          \u003cdiv class=\"stat-label\"\u003eGrit\u003c\/div\u003e\n        \u003c\/div\u003e\n        \u003cdiv\u003e\n          \u003cdiv class=\"stat-value\"\u003e50\u003c\/div\u003e\n          \u003cdiv class=\"stat-label\"\u003eDiscs Per Pack\u003c\/div\u003e\n        \u003c\/div\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eFast Material Removal for Rough Wood Prep\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\/20260623992_1.jpg\" alt=\"Mirka Ultimax Ligno 6-Inch Grit 40 Hook and Loop Sanding Discs stacked beside the product box for woodworking surface prep on wood with a 6-inch orbital sander\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis disc is built for the stage where you need to move material, not baby the surface.
