This is a sanding disc designed for surface preparation, stock removal, and finish removal on wood, fillers, plastics, and coated surfaces. Model Number: \u003cstrong\u003e20-342-080\u003c\/strong\u003e. If you need a value-focused abrasive that still cuts hard right out of the gate, this one is built to keep material moving without overcomplicating the job.\u003c\/p\u003e\n    \u003cp\u003eThe big selling point here is the cut. Mirka lists Basecut as an economical, high-efficiency choice with a high initial aggressive cut, and that matters when you are knocking down body filler, stripping old paint, or flattening rough wood before moving to finer grits. At \u003cstrong\u003e80 grit\u003c\/strong\u003e, this disc sits in the coarse range, so it is aimed at early-stage prep work rather than final finishing.\u003c\/p\u003e\n    \u003cp\u003eThe disc size is \u003cstrong\u003e6 inches \/ 150 mm\u003c\/strong\u003e, which is a common working size for orbital sanders in shops and jobsite finishing setups. The \u003cstrong\u003ePSA adhesive backing\u003c\/strong\u003e is the other practical part of the story. Instead of a hook and loop attachment, this uses pressure-sensitive adhesive for a firm hold on the pad. That direct bond can be a good fit when you want consistent contact and are running through discs steadily during repetitive sanding work.\u003c\/p\u003e\n    \u003cp\u003eMirka uses \u003cstrong\u003ealuminum oxide grain\u003c\/strong\u003e with a \u003cstrong\u003epaper backing\u003c\/strong\u003e, \u003cstrong\u003eresin over resin bonding\u003c\/strong\u003e, and a \u003cstrong\u003esemi-open coating\u003c\/strong\u003e. In plain terms, that gives you a familiar abrasive build for general-purpose sanding across a wide range of materials. It is not locked into one narrow task. Source data specifically calls out use on lacquers, paint removal, plaster, putty, plastic, wood, glass fibre, chipboard, veneer, body filler, hardwood, and soft or resinous wood.\u003c\/p\u003e\n    \u003cp\u003eThe \u003cstrong\u003eno-hole configuration\u003c\/strong\u003e is important to note before you buy. These discs are meant for pads that do not require dust extraction holes lined up through the abrasive. If your sander relies on a hole pattern for dust collection through the pad, this is not the version to grab. If you are working with a solid pad setup, the no-hole disc keeps things simple.\u003c\/p\u003e\n    \u003cp\u003ePackaging also matters on consumables, and this one comes as a \u003cstrong\u003e100-piece Linkroll\u003c\/strong\u003e. That is useful in a busy automotive, wood, or marine shop because you can keep a lot of the same grit ready to go without opening and stacking loose sleeves all over the bench. It is a straightforward way to stay stocked when a coarse grit is part of your normal prep sequence.\u003c\/p\u003e\n    \u003cp\u003eAs for who should buy it, this Mirka sanding disc makes the most sense for automotive refinish work, wood finishing prep, marine finishing prep, and general surface correction where you need coarse removal more than finesse. Pros who burn through abrasive and serious DIY users who want dependable discs in bulk will get the most value here. If your main need is fast surface prep on an orbital sander with PSA attachment, this is right in its lane.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n  \u003csummary\u003e\u003ch2\u003eBulk Discs for Repetitive Prep Work\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\/20260623596_1.jpg\" alt=\"Mirka Basecut 6 in Sandpaper 80 Grit PSA Linkroll adhesive sanding discs in linkroll form for orbital sander surface prep on wood and refinishing work\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eWhen you are doing repeated sanding steps, buying discs one sleeve at a time gets old fast.
