This is a \u003cstrong\u003ePSA sanding disc\u003c\/strong\u003e designed for surface sanding and finish prep. Model Number: \u003cstrong\u003e23-342-120\u003c\/strong\u003e. With a 6 inch diameter, 120 grit abrasive, and a 100-count roll, this pack is aimed at users who want a dependable sanding disc for repeat work without constantly stopping to reload.\u003c\/p\u003e\n      \u003cp\u003eThe main value here is the combination of Mirka's gold-series aluminum oxide abrasive and a practical 120 grit cut. That grit sits in a useful middle ground for many sanding steps, where you need enough bite to level a surface or clean up previous scratch patterns, but not such an aggressive cut that you leave a rough finish behind. If you do a lot of prep between heavier stock removal and final finishing, this is the kind of grit that earns its keep.\u003c\/p\u003e\n      \u003cp\u003eMirka also calls out a sharp, durable aluminum oxide grain along with an anti-loading stearate treatment. In plain terms, that matters because clogged discs stop cutting well and waste your time. A disc that resists loading keeps the abrasive exposed longer, which helps maintain more consistent sanding performance and can stretch disc life on jobs where dust buildup is usually the thing that kills the disc first.\u003c\/p\u003e\n      \u003cp\u003eThe PSA backing is another practical advantage. Sticky-back discs are straightforward to apply, hold securely to the pad, and make quick swaps easy when you're moving through material or changing worn abrasives. For shops and serious DIY users already set up for PSA discs, that means less messing around and a cleaner, flatter fit on the sanding surface.\u003c\/p\u003e\n      \u003cp\u003eThis Mirka sanding disc is a sensible choice for anyone running a 6 inch PSA sander or sanding pad and needing a bulk quantity of medium-grit discs. It makes the most sense for users who burn through abrasives regularly and care more about consistent cutting, predictable wear, and easy disc changes than flashy packaging. If you want a known abrasive from a brand people trust in sanding, this is a solid, work-ready option.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eFast Changes for Repetitive Sanding\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\/20260624314_1.jpg\" alt=\"Mirka 23-342-120 Gold 6 inch Sticky Back PSA Sanding Discs roll with loose discs for PSA sanding on wood, paint, and surface prep work in a shop setting\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eIf you use a PSA setup, this format keeps disc changes simple and efficient.
