The Mirka Q.Silver 5 Grip P400 Sanding Disc, model 2B-612-400, is a 5 inch hook and loop sanding disc sold in a 50-pack for fine sanding and surface preparation. This is a sanding disc designed for fine finishing and prep sanding. If you need a consistent abrasive for the later stages of sanding, this grit range is where you start cleaning up scratch patterns and getting surfaces ready for the next step.

The big thing here is the P400 grit. That puts this disc in the fine-sanding category, which makes it a solid choice when rough stock removal is already done and the goal is a more refined surface. For woodworkers, painters, automotive refinish users, and finish-focused shop work, that matters because the abrasive step right before coating or polishing often decides how the final surface looks.

Mirka built this as a 5 inch Grip disc, which means quick attachment and removal on sanders that use a hook and loop style backing pad. That saves time when you are changing worn discs or moving through sanding steps. On the bench or in a production setting, faster disc swaps mean less interruption and less temptation to keep sanding with an abrasive that is already spent.

This product is also a practical buy for higher-volume use because it comes in a pack of 50. For serious DIY users, cabinet shops, body shops, and general finishing work, having a full box of the same grit keeps your process consistent from one panel or part to the next. The Mirka Q.Silver 5 Grip P400 Sanding Disc is a straightforward choice for anyone who wants a known disc size, a fine grit for finish prep, and enough quantity to keep working instead of reordering every few days.
