The Mirka Q.Silver 6 Inch PSA P220 Sanding Disc, model 2B-342-220, is a 6 inch pressure-sensitive adhesive sanding disc sold in a pack of 100. This is a sanding disc designed for surface prep, smoothing, and finish-stage sanding where a finer abrasive step matters. If you use 6 inch PSA-backed sanding setups and need a consistent P220 grit for day-to-day work, this is the basic fit.

What matters here is the combination of size, grit, and backing format. The 6 inch diameter is a standard working size for many sanding applications, so you get broad coverage without stepping into a specialty format. The P220 abrasive is on the finer side, which makes it useful when the job is less about aggressive removal and more about refining the surface, cleaning up previous scratch patterns, or preparing material for the next finishing step.

The PSA backing is the other key detail. Pressure-sensitive adhesive discs are built for quick attachment to the correct pad, and they are commonly chosen when you want a secure hold during sanding. That matters on repeat work because the abrasive stays planted while you work, which helps keep the process consistent from disc to disc.

This Mirka abrasive is a straightforward consumable, but that does not make it unimportant. Sanding results depend heavily on using the right grit at the right stage. A P220 disc can be the difference between a surface that is ready for the next step and one that still needs rework. When the abrasive format, disc size, and grit all line up with your sander and your workflow, you waste less time swapping materials or correcting the finish.

The 100-count package also matters in real shop use. If you are running production work, doing repeated prep tasks, or just keeping consumables on hand, buying discs in pack quantities like this is more practical than piecing together smaller counts. It helps keep your process moving and gives you a consistent abrasive for the whole job instead of mixing whatever happens to be left on the shelf.

This Mirka Q.Silver 6 Inch PSA P220 Sanding Disc is best for users who already know they need a 6 inch PSA disc and want a finer grit for prep and finish work. That includes serious DIY users, finish-focused woodworkers, body and paint prep users, and shop environments where sanding consumables get used regularly. If your setup calls for PSA rather than hook-and-loop, and P220 is the grit your process needs, this is the right kind of pack to keep in rotation.
