This is a sanding disc designed for fine surface prep and controlled material removal. Model Number: 2B-342-400. If you need a 6 inch PSA sanding disc that sticks securely, cuts consistently, and comes in a high-count box for production work, this one is aimed right at that kind of use.\u003c\/p\u003e\n      \u003cp\u003eWhat matters here is the combination of grit, backing, and abrasive construction. The 400 grit rating puts this disc in the fine-sanding range, which makes it a practical choice when you're refining a surface rather than trying to strip it aggressively. According to the source data, Mirka's Q.Silver abrasive uses a flexible and durable latex paper backing with a full resin bond. In real use, that means the disc is built to stay useful when heat builds up and when the work calls for a steady, even scratch pattern.\u003c\/p\u003e\n      \u003cp\u003eMirka also positions this abrasive for demanding sanding tasks, including down-to-metal work, which tells you the abrasive is meant to hold up under tougher conditions than a bargain disc. The latex paper backing adds flexibility, which helps the disc conform better during hand-guided machine sanding and reduces the stiff, grabby feel you can get from lower-grade paper-backed abrasives. That kind of flexibility matters when you're working curves, body panels, edges, or shaped wood parts and you want more control.\u003c\/p\u003e\n      \u003cp\u003eThe PSA format is another practical advantage. Pressure-sensitive adhesive discs are straightforward: peel, stick, sand, replace. That makes this Mirka sanding disc a good fit for users who want a secure hold on a 6 inch backing pad without dealing with hook and loop wear or inconsistent attachment. In a shop setting, that can mean cleaner disc tracking and fewer interruptions once the disc is mounted correctly.\u003c\/p\u003e\n      \u003cp\u003eThis product is sold as a 100-count pack, which makes more sense for busy users than buying small sleeves one at a time. If you're running through discs in an auto body shop, marine repair bay, cabinet shop, or composite fabrication setup, having a box of the same grit on hand keeps your sanding sequence consistent and saves time during repeat jobs.\u003c\/p\u003e\n      \u003cp\u003eWho should buy it? This is a smart pick for automotive refinishing, marine work, composite processing, woodworking, and vehicle manufacturing applications where finish quality matters and consistent abrasive performance is worth paying for. If you already use a 6 inch PSA sander or matching backup pad and you need fine-grit discs from a proven abrasive brand, the Mirka 2B-342-400 Q.Silver 6 Inch PSA Linkroll Sanding Disc 400 Grit is the kind of stock item that earns its shelf space.\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 Consistent Finish 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\/20260623915_1.jpg\" alt=\"Mirka 2B-342-400 Q.Silver 6 Inch PSA Linkroll Sanding Disc 400 Grit roll and boxed pack for fine sanding and surface prep in shop work\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eFine-grit abrasive only helps if it stays consistent through the pass.
