The Mirka Galaxy Perforated Sanding Roll FY-570-150 is a hook and loop sanding roll built for hand sanding and strip sanding applications where you want clean tear-off sheets and consistent cut quality. This is a sanding roll designed for surface preparation, finish sanding, and material refinement on wood, metal, and epoxy resin. Model Number: FY-570-150.

What makes this roll useful on the bench or on the job is the format. Each roll is 2.75 inches wide by 33.5 feet long and perforated every 2.75 inches, giving you 146 sheets per roll. That matters because you can size sheets quickly without cutting them by hand, keep your workflow moving, and load up a sanding block or compatible sander with less waste.

Mirka pairs that format with Galaxy ceramic abrasive technology. The ceramic grain is designed to stay sharp as it wears, which helps the abrasive keep cutting instead of going dull early. There is also a non-clog coating, which is especially helpful when you are working on materials that tend to load paper, such as epoxy resin or coated surfaces. In plain terms, you spend less time changing paper and more time sanding.

The hook and loop backing adds convenience for anyone swapping abrasives often during prep and finish work. It is designed to fit 2.75 inch wide sanders and hand blocks, including blocks in 5 inch, 8 inch, and 16 inch lengths. That gives this Mirka sanding roll some flexibility whether you are doing quick hand sanding, detail touch-up, or longer passes on flatter surfaces.

For real-world use, 150 grit is a practical choice when you need more refinement than coarse surface stripping but still want enough bite to level and prep. It works well as a middle-stage abrasive in woodworking, metal finishing, and resin work where scratch control matters. If you are trying to leave a more uniform surface before moving to a finer grit, this is the range that makes sense.

Who should buy it? This is a good fit for woodworkers, finish carpenters, metal fabricators, cabinet shops, and serious DIY users who go through abrasive sheets regularly and want a cleaner, faster way to reload. If you already use 2.75 inch hook and loop sanding blocks or compatible sanders, the Mirka Galaxy Perforated Sanding Roll FY-570-150 is a practical upgrade over basic paper rolls.
