The Mirka FY-622-1500 Galaxy 6-Inch Hook and Loop Sanding Discs are ultra-fine abrasive discs made for finish sanding on epoxy resin, wood, and metal. This is a sanding disc designed for final surface refinement and scratch reduction. Model Number: FY-622-1500. If you need a clean, controlled finish instead of aggressive stock removal, this is the part of the sanding process where these discs earn their keep.

What matters here is the grit and the abrasive. At 1500 grit, these discs are aimed at the last stages of sanding, where you are cleaning up a surface, blending a previous scratch pattern, or getting material ready for polishing or topcoat prep. The ceramic alumina abrasive uses Mirka's self-sharpening grain approach, so the disc is meant to keep cutting instead of going dull early. That helps maintain a more even finish across the life of the disc.

Mirka's Galaxy line is also built around longer usable life with an anti-clogging design. On finish work, loading is what kills consistency fast, especially on resin and fine dust. A disc that resists clogging stays more predictable, cuts cleaner, and reduces the temptation to lean harder on the sander just to keep things moving.

The 6 inch format and hook and loop backing make these a practical fit for orbital sanders and sanding machines that use this common disc size. The supplied compatibility data also points to use with Mirka DEROS 625X CV and Mirka DEROS 650X CV, along with orbital sanders in general. That makes this a strong option for users already working in the Mirka sanding system or anyone running a compatible 6 inch hook and loop setup.

This pack includes 50 discs, which makes sense for repeat finish work where consistency matters from one panel or project to the next. Whether you are leveling cured epoxy, refining a wood surface before the last finishing steps, or smoothing metal before final prep, having the same grit and cut quality across a full box helps keep results uniform.

Who is this for? Woodworkers, finish carpenters, auto body and detailing users, epoxy resin makers, and serious DIYers who understand that the last sanding steps are where the finish is won or lost. If you are still shaping material, this grit is too fine. If you are already close and want to clean up the surface properly, this is exactly the kind of disc you reach for.
