This is a \u003cstrong\u003ePSA sanding disc designed for heavy sanding, stripping, and finishing prep\u003c\/strong\u003e. Model Number \u003cstrong\u003e23-332-040\u003c\/strong\u003e. With a coarse \u003cstrong\u003eP40 grit\u003c\/strong\u003e, this disc is a good fit for users who need an aggressive cut before moving on to finer grits.\u003c\/p\u003e\n      \u003cp\u003eMirka uses \u003cstrong\u003ealuminum oxide abrasive\u003c\/strong\u003e on this disc, which matters because it gives you a durable cutting surface that holds up well in demanding sanding work. On rough wood, metal, or stone, that means the disc keeps cutting instead of dulling out right away. The coarse grit profile is geared toward heavy material removal, not final finish work, so it makes sense where speed matters more than a polished surface.\u003c\/p\u003e\n      \u003cp\u003eThe \u003cstrong\u003epressure sensitive adhesive backing\u003c\/strong\u003e is the practical part of this design. PSA discs mount quickly to the correct backing pad and stay planted when you're pushing harder through stock removal work. If you prefer a simple peel-and-stick setup over hook-and-loop, this style is straightforward and secure, especially for shop sanding routines where you already run a PSA pad setup.\u003c\/p\u003e\n      \u003cp\u003eThis disc uses a \u003cstrong\u003epaper backing\u003c\/strong\u003e and a \u003cstrong\u003eno-hole design\u003c\/strong\u003e. That makes it a better match for sanding setups that do not rely on through-pad dust extraction. Mirka's Bulldog Gold line is known for heavy-duty sanding applications, and the product description also notes an anti-load stearate coating and high-strength resin bonding to help resist clogging and support grain retention during use.\u003c\/p\u003e\n      \u003cp\u003eThe 5-inch diameter is a common size for random orbit and other compatible sanding setups using PSA pads, which makes this a practical shop staple if you already run that format. The pack of \u003cstrong\u003e50 discs\u003c\/strong\u003e is also the right quantity for regular users who burn through coarse grits in prep work, filler leveling, or stripping jobs.\u003c\/p\u003e\n      \u003cp\u003eIf you do bodywork prep, woodworking cleanup, metal surface prep, or general shop sanding where aggressive cut speed matters, this Mirka disc makes sense. If you need finish-ready scratch patterns, step up to a finer grit. But if your job starts with removing material fast, the Mirka 23-332-040 Bulldog Gold-23 PSA Disc is aimed at exactly that part of the process.\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 to Remove Material Fast\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\/20260624619_1.jpg\" alt=\"Mirka 23-332-040 Bulldog Gold-23 PSA Disc 5 inch P40 heavy-duty sanding disc with packaging for workshop stock removal and surface preparation\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis coarse PSA sanding disc is made for the early part of the job, when the goal is removing material quickly and leaving the surface ready for the next sanding step.\u003c\/p\u003e\n          \u003cul\u003e\n            \u003cli\u003e5-inch disc size for common PSA sanding setups\u003c\/li\u003e\n            \u003cli\u003eP40 grit for aggressive stock removal and rough prep work\u003c\/li\u003e\n            \u003cli\u003eAluminum oxide abrasive with paper backing\u003c\/li\u003e\n            \u003cli\u003eNo-hole design for non-vacuum pad applications\u003c\/li\u003e\n          \u003c\/ul\u003e\n        \u003c\/div\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-whats-included\" class=\"acc\" open\u003e\n    \u003csummary\u003e\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"tnincluded-wrapper\"\u003e\n        \u003cul\u003e\n          \u003cli\u003e(50) Mirka Bulldog Gold-23 5 in.
