Mirka Oro 8 PSA DISCO 36G 50/PK is an 8 inch pressure-sensitive adhesive sanding disc pack built for fast material removal. This is a sanding disc designed for coarse sanding, surface prep, and heavy stock removal. Model Number: 23-352-036. If you need a disc that cuts hard at higher sanding speeds, this one is aimed at that kind of work.

The big selling point here is the 36 grit. That is a coarse abrasive, so this is not your finish pass disc. It is the one you reach for when you need to take material down quickly, clean up a rough surface, or get through old finishes and heavy imperfections before stepping through finer grits. For body shops, wood shops, and metal prep, that kind of cut rate saves real time.

Mirka's Gold abrasive line is known for durability, and the source data calls out that this product is well suited for sanding at high speeds. That matters because a disc that sheds performance early costs you twice: slower work and more disc changes. The semi-open grain bonding and special stearate coating are there for a practical reason, to reduce clogging and pilling so the abrasive keeps working instead of loading up too soon.

The 8 inch diameter makes this disc a fit for larger sanding platforms that use 8 inch PSA discs. PSA backing matters if that is the setup you run, because it gives you a secure bond to the sanding pad instead of relying on hook and loop. On the job, that means stable contact and a more even scratch pattern when you are leaning into aggressive sanding.

This Mirka sanding disc is not limited to one trade. The supplied product data specifically points to automotive refinishing, woodworking, metalworking, marine work, and vehicle manufacturing. That makes sense for a coarse abrasive like this. Whether you are stripping material, shaping filler, or doing early-stage prep before moving to finer grits, the disc is built for production-minded sanding rather than delicate finish work.

You are getting a 50-pack, which is the right format for a shop that goes through abrasives regularly and wants to keep the same cut and backing style on hand. If you already use 8 inch PSA sanding equipment and need a durable coarse sanding disc for tough prep work, this pack is a straightforward buy. If your work is mostly final sanding or finish prep, you will want a finer grit instead.
