This is a sanding disc designed for material removal in sanding applications using a pressure-sensitive adhesive attachment system. Model Number: \u003cstrong\u003e20-352-040\u003c\/strong\u003e. If you need a coarse \u003cstrong\u003eadhesive disc\u003c\/strong\u003e that gets to work quickly without jumping straight into a premium-priced option, this one makes sense.\u003c\/p\u003e\n    \u003cp\u003eWhat matters here is the combination of a coarse \u003cstrong\u003eP40 grit\u003c\/strong\u003e, an \u003cstrong\u003e8 inch\u003c\/strong\u003e disc size, and Mirka's Basecut positioning as an economical, high-efficiency abrasive. In plain terms, this disc is built to cut aggressively at the start, so you spend less time waiting for the abrasive to bite. That is useful when the job is more about removing material efficiently than chasing a fine finish.\u003c\/p\u003e\n    \u003cp\u003eThe \u003cstrong\u003ePSA backing\u003c\/strong\u003e is a practical detail, not just a catalog spec. If your sander or backup pad is set up for pressure-sensitive adhesive discs, this format gives you a direct, secure mount that stays planted during use. The liner helps protect the adhesive side before installation, which is important in a shop or jobsite environment where dust can ruin a good bond before the disc ever gets on the machine.\u003c\/p\u003e\n    \u003cp\u003eMirka describes Basecut as an economical line with productivity and efficiency features, and that fits where this disc belongs. You are getting a paper sanding abrasive aimed at users who need respectable performance and a long working lifespan without overcomplicating the choice. For sanding operations that go through discs regularly, long life matters because every disc change is downtime.\u003c\/p\u003e\n    \u003cp\u003eThis Mirka sanding disc is best suited to buyers who already know they need an \u003cstrong\u003e8 in PSA disc\u003c\/strong\u003e and want a coarse grit for heavier sanding steps. It is a straightforward fit for shops, maintenance departments, and serious DIY users who want dependable consumables from a known abrasive brand. If your process calls for aggressive sanding and your machine uses PSA paper, this is the kind of disc you keep on hand instead of scrambling for the right format when a rough-prep job lands on the bench.\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, Coarse
