PSA Sanding Disc 320 Grit\u003c\/strong\u003e, model \u003cstrong\u003e24-342-320\u003c\/strong\u003e, is a fine-grit abrasive disc sold in a 100-pack for sanding and surface prep work. This is a \u003cstrong\u003e6-inch PSA sanding disc designed for surface sanding and finish prep\u003c\/strong\u003e. If you need a disc for refining a surface before the next step, this grit range is the part of the process where scratch pattern matters and consistency matters even more.\u003c\/p\u003e\n    \u003cp\u003eWhat stands out here is the straightforward setup: 6 inch diameter, PSA backing, and 320 grit. That combination tells you exactly where this product lives in the workflow. The 6 inch format suits common disc sanding applications, while the pressure-sensitive adhesive style backing is meant for users who want a firm attachment to the pad without fussing with loose fitment. The 320 grit rating is a finer option, which makes it a practical choice when you are cleaning up previous sanding marks, refining a surface, or getting material ready for coating, paint, or final finishing steps.\u003c\/p\u003e\n    \u003cp\u003eBeing part of the Mirka Iridium line also matters for buyers who already know the brand and want to stay with a proven abrasive platform. On sanding products, consistency from disc to disc is a big deal. A box of 100 is not just a quantity spec, it is a workflow spec. It means this product is aimed at people who sand regularly enough to care about keeping the same grit and disc type on hand for repeatable results.\u003c\/p\u003e\n    \u003cp\u003eThe PSA format makes this Mirka sanding disc a fit for users who prefer adhesive-backed discs rather than a hook-and-loop style interface. That is worth paying attention to before you buy. If your setup is built around PSA pads, this is the right style. If your sander is set up for another attachment method, you will want to confirm pad compatibility first. That is the kind of small detail that saves time and frustration once the box lands on the bench.\u003c\/p\u003e\n    \u003cp\u003eFor shop use, the 100-pack count is the practical play. It works for anyone doing repeated prep on wood, primer, filler, paint, or other finish-sensitive surfaces where stepping up to a fine grit is part of the normal sequence. Instead of buying a few discs at a time and mixing brands or backing types, you get one consistent pack sized for real use.\u003c\/p\u003e\n    \u003cp\u003eWho should buy this? Painters, body and finish prep users, woodworkers, cabinet shops, and serious DIYers who already know they need a \u003cstrong\u003e320 grit 6 inch PSA sanding disc\u003c\/strong\u003e, not a coarse stripping disc and not a hook-and-loop disc. If your work depends on a finer finish stage and you want a box quantity that supports regular production, this Mirka abrasive is aimed right at that job.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n  \u003csummary\u003e\u003ch2\u003eFine Surface Prep Without Guesswork\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\/20260624215_1.jpg\" alt=\"Mirka Iridium 6 in.
