Mirka Gold 5-in. 240 Grit PSA Sanding Disc 100-Pack for Finishing (23-332-240)

The Mirka 23-332-240 Gold 5 in PSA Sanding Disc 240 Grit 100-Pack is a premium adhesive-backed sanding disc pack built for finish sanding and surface preparation across wood, automotive, marine, and industrial work. This is a sanding disc designed for fine surface sanding and prep before finishing. Model Number: 23-332-240. If you need a 5-inch PSA disc that cuts clean, resists loading, and gives you enough quantity to stay productive, this is the kind of consumable that earns its keep.

What matters here is the balance between finish quality and working life. The 240 grit abrasive is fine enough for smoothing and prep work without being so polished that it stops cutting altogether. On real jobs, that means you can refine filler, primer, sealer, wood surfaces, and painted panels with better control before your next step. The aluminum oxide grain is made for fast cutting, so you are not stuck waiting on a worn-out disc to do work it can no longer handle.

Mirka's Gold series is known for being a dependable shop abrasive, and the construction backs that up. The product data calls out a heavy-duty resin system and stronger C and D weight paper backings, which are built to hold up better than lighter paper alternatives. That matters when you are sanding edges, working curves, or putting in longer sessions where cheap discs start tearing, curling, or giving up early.

The anti-loading stearate treatment is another practical feature, especially if you work with materials that like to gum up abrasives. A disc that resists clogging stays cutting longer and leaves a more even scratch pattern. That saves discs, saves time, and helps avoid the temptation to keep sanding with a loaded disc that is really just heating up the surface instead of refining it.

Because this is a PSA sanding disc, it is meant for sanders and backup pads that accept pressure sensitive adhesive discs. If you already run a PSA setup, the benefit is simple: quick attachment, solid hold, and easy swap-out when the disc is spent. This style is especially useful in production environments and finish work where repeatability matters and you do not want the disc shifting during use.

The 5-inch size is a common format for shop sanding tasks, which makes this Mirka abrasive a straightforward choice for users who want a familiar, easy-to-stock consumable. The 100-disc box also makes sense for anyone doing routine prep work instead of one-off hobby use. A full box means fewer interruptions and a lower chance of running short in the middle of a job.

Who should buy it? Body shops, cabinet shops, marine shops, finish carpenters, woodworkers, and serious DIY users who burn through abrasives and know the difference between bargain paper and paper that stays useful. If your work depends on consistent sanding results and you use a PSA sander setup, this Mirka 23-332-240 Gold 5 in PSA Sanding Disc 240 Grit 100-Pack is a smart stock item.
