This is a sanding disc designed for fine surface finishing on wood, metal, and similar materials. Model Number: 23-608-400. If you need a small abrasive disc that cuts cleanly, resists loading, and leaves a more consistent scratch pattern, this is the kind of consumable that makes the last sanding steps easier to control.\u003c\/p\u003e\n    \u003cp\u003eWhat matters here is the combination of 400 grit aluminum oxide abrasive and Mirka's Bulldog Gold construction. A 400 grit disc is typically where you are refining the surface, not trying to hog material off fast. That makes it useful for prep work before coating, paint correction stages that call for fine sanding, and general finishing work where a rougher disc would leave more cleanup behind.\u003c\/p\u003e\n    \u003cp\u003eMirka describes this disc as suited for both finishing and heavy stock removal, but the actual grit rating tells the real story for this model. In 400 grit, the value is finish quality and surface control. The aluminum oxide grain is there to keep the cut consistent and long-lasting, while the high-strength resin bond supports the grain so the disc holds up under high-speed sanding better than cheaper abrasives that fade quickly.\u003c\/p\u003e\n    \u003cp\u003eOne of the more useful details is the semi-open coat with a stearate coating. That matters because loaded discs stop cutting efficiently and can leave a messier result. By helping resist clogging and pill forming, the disc stays usable longer and maintains a more even scratch pattern. For anyone doing repetitive finish sanding, that means fewer interruptions and less guessing about when the abrasive has stopped doing its job.\u003c\/p\u003e\n    \u003cp\u003eThe 3 inch size is a practical fit when you need better control in tighter work areas or on smaller sanding pads. It is easier to manage on detail sanding tasks than a larger disc, especially when you are working around edges, smaller parts, or surfaces where precision matters more than broad coverage. Hook and loop backing also speeds up disc changes, which is a small thing until you are changing abrasives all day.\u003c\/p\u003e\n    \u003cp\u003eMirka positions this abrasive for automotive refinishing, wood processing, metal processing, marine work, and general manufacturing. That lines up with what this disc is best at: fine sanding where surface quality counts. If you are a body tech, woodworker, metal fabricator, or serious DIY user who cares about scratch consistency and cleaner sanding performance, this Mirka disc makes sense. If you need aggressive material removal, you would step down to a coarser grit. If you are in the finishing stage, this is the right end of the grit range to be looking at.\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 Constant Loading\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\/20260624275_1.jpg\" alt=\"Mirka 23-608-400 Bulldog Gold Grip Disc package and 3 inch sanding disc for fine surface prep and finish sanding in shop use\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eThe Mirka 23-608-400 Bulldog Gold Grip Disc is built for the sanding stages where surface quality matters most.
