The Mirka 23 Series Gold 8 in. Heavy Duty Disc, model 23-352-080, is a sanding disc built for general-purpose surface preparation and material removal. This is a sanding disc designed for sanding, polishing, and finishing tasks where you want broad coverage and a durable abrasive. If you run an 8 inch PSA disc setup and need a dependable 80-grit option, this is the kind of disc that makes sense for day-to-day shop work.

The big selling point here is the combination of an 8 inch diameter and P80 grit. That gives you enough bite for stripping, leveling, and prep work without stepping all the way into ultra-aggressive coarse grits. For users working across flat surfaces, the larger disc size helps cover more area per pass, which can save time compared to smaller sanding discs.

Mirka lists this as a heavy-duty disc with E-weight backing, and that matters. Backing weight is not just a line on a spec sheet. A heavier backing generally means the disc stands up better when you lean on it, especially in tougher sanding applications where lighter paper can curl, tear, or wear out too quickly. For buyers comparing abrasive discs, that is one of the practical details worth paying attention to.

This Mirka abrasive also sits in the Gold series, a line known for general sanding use. Based on the available product data, it is intended for sanding, polishing, and finishing applications, so it fits best in shops and workspaces that need a versatile abrasive rather than a highly specialized one-purpose disc. The coated abrasive construction supports consistent contact across the work surface.

The product data also points to PSA disc use, which is worth noting for anyone matching discs to an existing sander or backup pad. Before ordering, the main thing to confirm is that your tool accepts 8 inch pressure-sensitive adhesive sanding discs. That is the real make-or-break detail with abrasives like this.

Who should buy it? This is a good fit for users who already know they want an 8 inch PSA sanding disc in 80 grit and need quantity for repeat work. It makes the most sense in production sanding, prep work, and finishing workflows where disc changes happen often and consistency matters more than gimmicks.

Simple abrasive, solid specs, no nonsense
