This is a sanding disc designed for general sanding and finish prep on wood, coatings, fillers, plastics, and non-ferrous metals. Model Number: 23-379-080. If you run a sander that takes PSA discs, this gives you a straightforward 80 grit option in bulk.\u003c\/p\u003e\n      \u003cp\u003eThe main thing that matters here is the abrasive itself. Source data calls out a sharp, durable aluminum oxide grain, which is a proven choice when you need a disc that cuts consistently and holds up through repeat sanding cycles. In practical terms, that means less time fighting a dull disc when you are knocking down filler, stripping paint, leveling primer, or prepping hardwood before moving to finer grits.\u003c\/p\u003e\n      \u003cp\u003eThis Mirka sanding disc is a no-hole design, so it is built for applications where a solid face disc is the right match. The 6 inch diameter fits sanders set up for 6 inch PSA paper, and the adhesive backing is the key difference versus hook and loop sanding discs. If your machine is set up for stick-on discs, PSA keeps the attachment simple and secure.\u003c\/p\u003e\n      \u003cp\u003eFor shop work, the 80 grit rating lands in a useful middle zone for aggressive prep without being as coarse as a heavy stripping grit. It is a practical choice for body filler, primer, paint sanding, plaster and filler, veneer, chipboard, hardwood, soft or resinous wood, lacquers, plastics, and synthetic materials based on the source data. That makes this a versatile sanding disc for automotive prep, woodworking, finishing, and general repair work.\u003c\/p\u003e\n      \u003cp\u003eMirka also notes a bonded construction with aluminum oxide abrasive. The benefit there is durability and a predictable cut, especially when you are working through a box over multiple jobs. A 100-piece box is the right format for users who burn through abrasives regularly, whether that is in a cabinet shop, body shop, or a serious home garage.\u003c\/p\u003e\n      \u003cp\u003eCompatibility matters with abrasive discs, and this one is not universal. It is for 6 inch PSA setups, not hook and loop pads. Source data also notes fitment for Porter Cable 7336 and 337 with a holed pad, but the important buying check is still the backing style on your machine. If your tool takes 6 inch adhesive-backed discs, this is the right category. If your tool requires hook and loop attachment, this is the wrong disc.\u003c\/p\u003e\n      \u003cp\u003eWho should buy it? Anyone who already knows they need a 6 inch PSA sanding disc and wants a bulk box from a known abrasive brand. It makes the most sense for painters, body and finish prep users, woodworkers, and repair shops that need steady cutting performance on common prep materials. If you only sand occasionally, a smaller pack may be enough. If you go through discs every week, the 100-pack is the better buy.\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 Fast Surface 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\/20260624283_1.jpg\" alt=\"Mirka 23-379-080 6-Inch No-Hole 80 Grit Adhesive Sanding Discs, 100-Pack in dispenser box for shop sanding, prep work, and repeated abrasive changes\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis pack is aimed at people doing real prep work, not one-off touchups.
