The Mirka 23-622-220 Grip Disc is a 6 inch P220 sanding disc sold in a 50-pack for finish sanding and surface preparation. This is a hook and loop sanding disc designed for fine sanding before coating or final finishing. Model number 23-622-220. If you need a consistent abrasive for moving from shaping to finish-ready prep, this grit lands in the sweet spot where you are refining the surface instead of removing a lot of material.

What matters here is the combination of a 6 inch diameter, P220 grit, and aluminum oxide abrasive. In real use, that gives you a disc that works well when the heavy stock removal is already done and the job now is to smooth, blend, and prep. P220 is a practical choice for final passes on many sanding jobs because it helps tighten up the scratch pattern and leaves a more controlled surface for the next step.

The aluminum oxide abrasive is a proven all-around material for sanding. It is commonly chosen because it offers a good mix of cutting ability, finish quality, and value. On a disc like this, that means you get a reliable abrasive for general-purpose sanding work without overcomplicating the setup. The semi open coat also matters because the abrasive coverage is arranged to help the disc stay productive during sanding rather than loading up as quickly as a fully dense coat can in some applications.

Mirka pairs that abrasive with a C-weight paper backing in its Gold series. That backing weight is important because it gives the disc enough body for machine sanding while still staying usable for controlled finish work. In plain terms, the disc is not flimsy, and it is not so stiff that it becomes awkward for finer surface prep. That balance is exactly what you want in a finishing abrasive that has to cut cleanly and still leave a controlled result.

This version is a no-hole disc, so it is the right fit for setups that do not require a vacuum hole pattern in the abrasive. That is a key buying detail. If your sander uses a solid backup pad or you are matching a no-hole setup on purpose, this disc keeps the contact surface simple and consistent. If your work depends on pad-based dust extraction through the disc, you will want to match the hole pattern to your machine instead of forcing the wrong format.

The pack quantity of 50 also makes this a practical shop consumable rather than a one-off purchase. If you are sanding in batches, keeping multiple grits on hand, or stocking abrasives for repeated prep work, a 50-pack reduces the stop-and-start that comes with buying small quantities. For pros, that is a workflow advantage. For serious DIY users, it means you can stay on schedule instead of rationing discs halfway through a project.

Who should buy it? This Mirka sanding disc makes the most sense for painters, woodworkers, finish carpenters, body and prep work users, and anyone doing repeatable surface prep with a 6 inch grip-style sander. If your work is already in the fine-sanding stage and you need a dependable P220 disc from a known abrasive brand, this is the kind of consumable that earns its keep by being consistent from disc to disc.
