This is a vacuum disc designed for general sanding applications where clean dust control, consistent cut, and quick disc changes matter. Model Number: 23-321-100. With a P100 grit, paper backing, and aluminum oxide abrasive, it is a practical fit for users who need a reliable coated abrasive disc for day-to-day finishing and prep.\u003c\/p\u003e\n      \u003cp\u003eWhat matters here is how the spec package works together. The 5-inch diameter fits a common sander size, the 5-hole pattern supports vacuum-assisted dust pickup, and the pressure sensitive adhesive backing gives you a firm mount on compatible sanding pads. That combination helps reduce loading, keeps the work area cleaner, and makes disc swaps straightforward when you are moving through multiple grits.\u003c\/p\u003e\n      \u003cp\u003eThe abrasive itself is aluminum oxide, which is a proven choice for general-purpose sanding. It gives a good mix of cut rate and usable life without turning this into an overly specialized disc. The P100 grit sits in a useful middle range for stock removal that still leaves you set up for the next finishing step, whether you are leveling a surface, refining previous sanding marks, or handling prep before coating.\u003c\/p\u003e\n      \u003cp\u003eMirka uses a paper backing on this Bulldog Gold-23 series disc, which keeps the disc flexible enough for common sanding work while staying cost-effective for volume use. Since this is a coated abrasive disc, it is built for controlled, even contact across the sanding face rather than aggressive grinding. For contractors, cabinet shops, auto body prep users, and serious DIYers, that usually means a more predictable sanding pattern and less wasted material.\u003c\/p\u003e\n      \u003cp\u003eDust collection is a real advantage with this style of abrasive. A 5-hole vacuum disc works best when matched with the right backing pad and extraction setup, helping fine dust move through the disc instead of hanging on the work surface. That improves visibility, cuts cleanup time, and can help the abrasive stay effective longer during repeated sanding passes.\u003c\/p\u003e\n      \u003cp\u003eThis Mirka sanding disc is best for users already running a compatible 5-inch PSA sanding setup and who want a bulk pack they can keep at the bench or on the truck. If you need a straightforward coated abrasive disc for surface prep, general sanding, and vacuum-assisted work, this is the kind of consumable that earns its spot by doing exactly what it should without drama.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eMirka 23-321-100 Vacuum Disc for Cleaner 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\/20260624336_1.jpg\" alt=\"Mirka 23-321-100 Vacuum Disc 5 inch PSA sanding disc with 5-hole pattern for dust-extracted surface sanding in shop prep work\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis disc is built for users who want faster sanding changes and less dust hanging around the work.
