This is a \u003cstrong\u003esanding disc\u003c\/strong\u003e designed for \u003cstrong\u003ewood sanding and material removal\u003c\/strong\u003e. In this 40 grit version, the focus is fast stock removal, surface leveling, and early-stage prep on wood surfaces where you need the abrasive to keep cutting instead of packing up with dust.\u003c\/p\u003e\n\u003cp\u003eWhat separates this disc from generic orbital sander paper is how the abrasive surface is laid out. Mirka uses an hourglass abrasive pattern with dust channels that direct debris toward the Multifit extraction holes. On the job, that matters because wood dust is what usually kills cutting speed. When dust has somewhere to go, the grains stay exposed longer, the disc runs cleaner, and you spend less time fighting loaded paper.\u003c\/p\u003e\n\u003cp\u003eHeat control is another real advantage here. Mirka states that air circulates under the abrasive, which helps reduce heat during sanding. With wood, especially resinous species or coated surfaces, extra heat can turn fine dust into a gummy mess that clogs the disc and drags the finish quality down. Keeping the disc cooler helps maintain a more even cut and extends useful disc life.\u003c\/p\u003e\n\u003cp\u003eThe backing is designed for flexibility and better edge wear resistance thanks to an improved resin system and latex impregnated paper. That is worth paying attention to if you sand edges, profiles, or areas where cheaper discs usually curl, crack, or wear through too quickly. For cabinet parts, furniture components, flooring work, and general shop prep, that added flexibility makes the disc easier to control without giving up durability.\u003c\/p\u003e\n\u003cp\u003eFitment is straightforward. These are 5 inch grip discs with a hook and loop attachment for standard 5 inch orbital sanders. The Multifit hole layout is built to work with dust extraction, which is a big part of why these make sense for anyone sanding wood regularly. Better extraction means a cleaner work area, less airborne dust, and more consistent sanding from disc to disc.\u003c\/p\u003e\n\u003cp\u003eThis 40 grit version is the coarse option in the Ultimax Ligno line, so it is best used where speed matters more than finish-ready scratch patterns. Think heavy prep, flattening, stripping back rough material, and knocking down surface inconsistencies before stepping to finer grits. If you do woodworking for a living, build cabinets, refinish floors, or handle frequent wood prep in a remodeling environment, this is the kind of abrasive that earns its keep quickly.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\u003csummary\u003e\u003ch2\u003eKeep Dust Moving During Heavy Sanding\u003c\/h2\u003e\u003c\/summary\u003e\u003cdiv class=\"acc-body\"\u003e\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"img\"\u003e\u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/20260623217_1.jpg\" alt=\"Mirka Ultimax Ligno 5 Inch Multifit Grip Discs sanding disc front side with Multifit extraction hole pattern for wood sanding on orbital sanders\" class=\"tnblock-img\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"copy\"\u003e\n\u003cp\u003eWhen you are removing material with a coarse grit, dust management is the difference between a disc that keeps biting and one that quits early.
