Mirka 23 Series Gold 6-in. 320 Grit Grip Sanding Disc for High-Speed Sanding (23-622-320)

The Mirka 23 Series Gold 6 in. Grip Disc is a 6-inch sanding disc built for fine surface preparation and finish sanding. This is a sanding disc designed for dry sanding primer, lacquer, putty, and similar coated surfaces. Model Number 23-622-320. If you need a disc for high-speed sanding that stays useful longer by resisting loading, this is the kind of abrasive that makes the job easier.

What matters here is how the disc is built. Mirka uses aluminum oxide abrasive for quick cutting and solid durability, which gives this sanding disc the ability to remove material efficiently while still leaving a controlled scratch pattern. In 320 grit, it lands on the finer side of the range, so it is better suited to smoothing and prep work than heavy stock removal.

The Gold series is meant to be an all-around abrasive, but the product data gives a clear use case split. Coarser grits in this line are recommended for sanding putty or removing lacquer, while finer grits like this one are suited for dry sanding surfaces with primer and lacquer. That makes this particular Mirka sanding disc a practical choice for paint prep, finish sanding, and surface correction where you want refinement instead of rough cutting.

One of the more useful details is the semi-open grit binding paired with a special stearate coating. That combination is designed to reduce clogging and pill forming, which is a big deal when you’re working on finishes and coatings that can quickly load up a disc. Less loading means more consistent cutting, less wasted time swapping discs, and a more uniform surface before the next step.

The 6-inch size and grip-style attachment make it a straightforward fit for sanders that use hook-and-loop style discs in this diameter. The grip backing also makes disc changes faster, which matters when you’re moving through grit changes during surface prep. For body work, paint work, woodworking prep, or general shop sanding, that kind of convenience adds up over the course of the day.

If you are a painter, body shop tech, woodworker, cabinet installer, or serious DIYer doing finish prep, this is the type of abrasive that makes sense when surface quality matters. The Mirka 23 Series Gold 6 in. Grip Disc is not about brute-force removal. It is about controlled sanding, cleaner operation on coated surfaces, and getting a surface ready for the next coat or the final finish.
