The Mirka 23-352-400 Gold 8 PSA P400 sanding disc is a fine-grit abrasive disc for surface sanding and finish prep. This is a sanding disc designed for fine sanding, surface refinement, and prep work before finishing or the next abrasive step. Model Number 23-352-400. If you need an 8 inch disc in a shop-friendly pack size, this one gives you a P400 grit disc from Mirka's Gold line in a 50-pack.

What matters here is the combination of disc size, grit, and pack count. The 8 inch format gives you broad coverage on larger workpieces, while the P400 grit is aimed at lighter material removal and more controlled finishing work. That makes it a better fit for smoothing and prep than aggressive stock removal.

The Mirka Gold series is widely recognized as a general-purpose abrasive line, and this specific configuration keeps things straightforward. You are getting a pressure sensitive adhesive sanding disc in a clearly defined 8 inch size with a clearly defined P400 grit. That kind of simple spec set is exactly what buyers want when they are matching discs to an existing sanding process.

For buyers who go through abrasives regularly, the 50-pack matters just as much as the grit. It is enough quantity for production runs, refinishing work, and routine shop inventory without jumping straight into bulk case quantities that may be more than a smaller operation needs.

This product makes the most sense for users who already know they need an 8 inch PSA disc and want a fine finishing grit from a known abrasive brand. It fits body shop, woodworking, finishing, and general surface prep workflows where consistent grit and predictable replacement quantity matter more than flashy extras.
