This is a hook and loop sanding disc designed for fine finishing work on sanders that accept this style of disc. Model Number: 23-612-320. If you are trying to clean up a surface without leaving a deep scratch pattern, this grit range is where the work starts getting serious.\u003c\/p\u003e\n    \u003cp\u003eWhat matters here is the balance of size, grit, and abrasive type. The 320 grit rating puts this disc in the finishing category, where the goal is smoothing, blending, and prepping a surface for the next step rather than removing a lot of material. The aluminum oxide abrasive gives you a familiar, controlled cut that works well when you need consistent finish quality.\u003c\/p\u003e\n    \u003cp\u003eThe 5-inch diameter is the standard size a lot of pros and serious DIY users already run, so it is easy to work across broad faces while still keeping good control around edges and tighter sections. The coated abrasive construction is built for sanding duty, and the grip-style backing is meant for quick disc changes so you can move from one grit stage to the next without wasting time.\u003c\/p\u003e\n    \u003cp\u003eThis Mirka sanding disc makes the most sense for users doing finish prep, light refinement, and final sanding passes where surface quality matters more than raw removal speed. If you work in woodworking, refinish surfaces, or handle detailed prep before coating, the Mirka 23-612-320 Bulldog Gold Grip Disc fits that kind of job well.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n  \u003csummary\u003e\u003ch2\u003eControlled Finish for Final Prep\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\/20260625201_2.jpg\" alt=\"Mirka 23-612-320 Bulldog Gold Grip Disc 5-inch hook and loop sanding disc with box, extra fine abrasive disc for finish sanding and surface prep in the shop\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eWhen you are past rough shaping and into finish prep, grit choice matters more than brute force.
