The Mirka 23-388-150 5 in. 150 Grit No-Hole Adhesive Sanding Disc is a pressure sensitive adhesive sanding disc made for general-purpose sanding, surface prep, and finish work. This is a sanding disc designed for smoothing wood, metal, paint, and coatings on compatible disc sanders and orbital sanders that accept adhesive-backed discs. Model Number: 23-388-150. If you need a reliable 150 grit disc that balances material removal with a cleaner finish, this is right in that useful middle ground.

What matters here is the abrasive package. Mirka uses aluminum oxide grain for fast cutting and solid life, which makes this disc a practical choice for shops and jobsite users who need one disc that can handle more than one material. The 150 grit rating is a strong fit for intermediate sanding steps, light stock removal, and refining a surface before moving to finer grits. It is aggressive enough to keep work moving, but not so coarse that it leaves a rough scratch pattern you have to fight later.

The disc uses a no-hole design and a pressure sensitive adhesive backing. That gives you a full-face abrasive surface and a straightforward stick-on attachment method. On the job, that means quick changeovers and consistent contact across the pad when you're sanding flat surfaces. If your sander is set up for PSA discs instead of hook and loop, this is the kind of consumable that keeps things simple.

Mirka also calls out a high-strength resin bond, a semi-open coat, and a stearate coating. Those details are not filler. The resin bond helps support the abrasive grain so it stays productive longer. The semi-open coat helps keep the scratch pattern more even. The stearate coating is there to fight loading and clogging, which is especially useful when you're sanding finishes, paint, or other materials that tend to pack up the disc and kill performance early.

The backing is paper, with listings describing it as D-weight latex paper. In practical terms, that gives the disc enough body for machine sanding while still letting it conform better than a stiffer fiber-style disc. For general wood sanding, paint prep, and refinishing work, that balance usually works well. It is an all-purpose abrasive, not a one-trick specialty disc.

This Mirka sanding disc is sold in a 100-count box, which makes sense for anyone who sands regularly and does not want to reorder every week. It is a good fit for cabinet shops, auto body prep, finish carpentry, remodeling, and serious DIY users who want dependable discs in bulk. If your setup uses 5 inch PSA discs and you want a proven all-around option for wood, metal, paints, and coatings, this is an easy one to justify.
