This is a sanding disc designed for finish sanding on wood, metal, plastic, fiberglass, and refinishing surfaces. Model Number: 23-332-400.\u003c\/p\u003e\n      \u003cp\u003eWhat matters here is the combination of a fine 400 grit and Mirka's Gold abrasive line. A 400-grit disc is not your first step when you need to remove a lot of material. It is the kind of disc you reach for when the surface is already close and you need to refine it, clean up the scratch pattern, or get a piece ready for the next coating or finishing stage.\u003c\/p\u003e\n      \u003cp\u003eThe abrasive material is aluminum oxide, which is a proven choice for general-purpose sanding because it cuts well and holds up under regular shop use. Mirka also calls out a semi-open coat and stearate coating in the product data. In plain terms, that means the disc is built to resist clogging and loading better than a basic paper disc, which helps the cut stay more consistent and keeps you from burning through consumables too quickly.\u003c\/p\u003e\n      \u003cp\u003eThis disc uses a PSA backing, so it is meant for tools and backup pads that accept pressure-sensitive adhesive discs. That gives you a firm, direct attachment that many finishers like for flat, controlled sanding. The listed format is no holes, so it is geared toward applications and pad setups where a hole pattern is not required.\u003c\/p\u003e\n      \u003cp\u003eMirka positions this abrasive as an all-around sanding material, and the use cases in the source data back that up. It is suited for automotive refinishing, wood processing, metal processing, marine work, and vehicle manufacturing. That makes it a practical consumable for body shops, cabinet shops, fabrication work, and serious DIY users who care about a predictable finish instead of just getting through the job.\u003c\/p\u003e\n      \u003cp\u003eIf you already use 5-inch PSA sanding discs and need a fine grit for finish work, this is the kind of consumable that makes sense to keep on the shelf. It is especially useful for users who want a durable abrasive, a consistent scratch pattern, and the simplicity of PSA attachment in a 100-count box.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eBuilt for Clean Finish 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\/20260624351_1.jpg\" alt=\"Mirka 23-332-400 5-Inch 400 Grit Gold PSA Disc box and disc for finish sanding in automotive, woodworking, and fabrication shop use\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis is the grit range you use when the surface is already shaped and you need refinement, not rough cutting.
