The Mirka 23-388-220 adhesive sanding disc is a 5 inch P220 abrasive disc built for fine sanding and surface prep. This is an adhesive sanding disc designed for finish sanding wood, metal, paint, and coatings. Model Number: 23-388-220. If you need a finer grit disc for smoothing surfaces, blending previous sanding steps, or getting material ready for paint or topcoat, this one is aimed right at that kind of work.

What matters here is how the spec package works together. The 220 grit rating gives you a finer cut than coarse stock-removal discs, which makes it better suited to surface refinement and prep work where scratch quality matters. Mirka uses aluminum oxide abrasive, a common pro choice because it cuts cleanly and holds up well across a mix of materials instead of being limited to just one job. That means the same box can cover wood parts, painted panels, coated surfaces, and light metal sanding tasks without feeling like a compromise.

This Mirka sanding disc also uses a paper backing with pressure-sensitive adhesive, so it is meant for PSA-style attachment rather than a hook-and-loop pad. If your setup is built around adhesive-backed discs, that is a simple, dependable format that stays put during sanding. The no-hole design is worth paying attention to as well. It skips hole alignment and keeps setup simple, especially on compatible non-vacuum applications or when dust extraction hole matching is not part of the workflow.

Mirka's Gold line is known for being a practical, everyday abrasive rather than a fussy specialty sheet. The source data calls out a semi-open coat and a special stearate treatment intended to reduce clogging and pilling. In real use, that matters most when you are sanding paints, coatings, fillers, or other materials that can load up a disc early and kill cut speed. Less loading means more consistent sanding, better surface quality, and fewer disc changes through the day.

This pack size also makes sense for users who burn through abrasives regularly. With 100 discs in the box, it is set up for production work, shop use, and repeatable prep jobs instead of the occasional one-off repair. That is a better fit for anyone who would rather buy once and keep the same abrasive on hand instead of mixing random discs from different brands and getting inconsistent results from one batch to the next.

For compatibility, the key points are the 5 inch diameter, PSA adhesive backing, and no-hole pattern. Those specs determine whether the disc fits your sander or sanding pad. It is best for users running 5 inch PSA-capable orbital sanding setups or compatible hand sanding applications. If your machine requires a hook-and-loop disc or a hole pattern for dust extraction, this is not the right disc style.

Who should buy it? Woodworkers, finish carpenters, painters, refinishers, body shop users, and serious DIYers who need a reliable fine-grit disc in quantity. The Mirka 23-388-220 adhesive sanding disc is especially useful when surface quality matters more than aggressive removal, and when you want a known abrasive that can move between different materials without changing your whole sanding system.
