This is a perforated sanding roll designed for hand sanding and sanding block work where you want fast cutting, clean dust flow, and easy tear-off sheet sizing. Model Number: \u003cstrong\u003eFY-570-100\u003c\/strong\u003e.\u003c\/p\u003e\n      \u003cp\u003eThe main advantage here is the combination of ceramic alumina abrasive and Mirka's self-sharpening grain behavior. In plain terms, the grit keeps exposing fresh cutting edges as it wears, so the sheet keeps working instead of going dull too quickly. For anyone sanding larger surfaces or doing repeated prep cycles, that matters because it helps maintain a more even scratch pattern and reduces the number of sheets you burn through.\u003c\/p\u003e\n      \u003cp\u003eThe 2.75-inch width and 33.5-foot roll format make this a practical choice for shops and serious DIY users who do not want to sort through stacks of loose cut sheets. The roll is perforated every 2.75 inches, giving you 146 sheets per roll. That makes it easy to tear off consistent pieces for smaller blocks or longer hand sanding blocks without guessing at size every time.\u003c\/p\u003e\n      \u003cp\u003eDust management is a big part of why this abrasive stands out. The perforated pattern is built for sanding blocks that use hole patterns to move dust away from the work surface. Mirka also calls out a non-clogging anti-adhesive coating, which is important when you are working on materials that tend to load paper fast, such as finishes, resin, or coated surfaces. Cleaner abrasive usually means a smoother result and less heat buildup on the workpiece.\u003c\/p\u003e\n      \u003cp\u003eFrom a job-use standpoint, Grit 100 sits in a useful range for material removal and surface prep before moving to finer sanding steps. It is coarse enough to cut efficiently but still controlled enough for leveling and preparation work where you need to keep the surface manageable for follow-up grits. If you are shaping filler, prepping wood, knocking down cured resin, or refining a coated surface before the next stage, this grit makes sense.\u003c\/p\u003e\n      \u003cp\u003eThis Mirka sanding sheet roll is made to work with 2.75-inch wide sanding blocks and is specifically noted as suitable for varying block lengths, including 5-inch, 8-inch, and 16-inch formats. That gives it flexibility for bench work, panel prep, marine finishing, bodywork, and general hand sanding where you want the control of a block but the convenience of roll-fed abrasive.\u003c\/p\u003e\n      \u003cp\u003eWho should buy it? This is a smart pick for painters, woodworkers, marine finishers, auto body users, finish carpenters, and anyone doing regular hand sanding with a dust-ready block. If you need a basic bargain sandpaper roll, this is more product than you need. If you care about cut quality, longer abrasive life, and cleaner sanding on demanding materials, this is the kind of abrasive worth stepping up to.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eConsistent Sheets, Less Waste\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\/20260623542_1.jpg\" alt=\"Mirka Galaxy Perforated Sanding Roll 2.75'' x 33.5' Grit 100 roll with perforated tear-off sanding sheets for hand sanding and sanding block surface prep\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThe perforated format gives you repeatable sheet sizing without cutting every piece by hand.
