Key Features
Overview
The Mirka Gold Adhesive Sandpaper Discs 23-388-180 are 5-inch, 180-grit sanding discs sold in a 100-piece pack. This is a sanding disc designed for surface preparation, finish sanding, and general material removal on wood, composites, paint, and coatings. Model Number: 23-388-180. If you need a dependable refill for a 5-inch sanding setup, this is the kind of abrasive that keeps moving instead of loading up early and wasting time.
What matters here is the combination of grit, grain, and format. A P180 abrasive sits in a useful middle ground for a lot of shop and jobsite work. It is fine enough for smoothing and prep, but still has enough bite to clean up surfaces efficiently. That makes it a practical pick for woodworkers, refinishers, body shop users, and anyone doing repeat sanding where consistency matters more than flashy claims.
Mirka Gold uses aluminum oxide abrasive, which is a proven choice for all-around sanding. In plain terms, it cuts fast, holds up well, and works across more than one material type, so you are not stuck keeping separate discs around for every small task. The product description also calls out a semi-open coating with a special stearate layer designed to reduce clogging and pill forming. On real sanding work, that matters because clogged discs cut slower, run hotter, and leave a rougher scratch pattern.
The 5-inch diameter is the standard size a lot of users already run, so replacement and workflow stay simple. These are no-hole discs, which can be the right call when you want uninterrupted abrasive contact across the face of the disc. That full surface can be useful for certain prep and finishing tasks where hole patterns are not part of your setup requirements.
Backing and build quality also matter with abrasives, and this disc uses a paper backing. For a general-purpose sanding disc, that helps keep the product flexible enough for smooth machine sanding while still offering the durability needed for production-style use. Mirka also notes a sharp, durable grain and a resin bond system intended to support long service life and steady cutting action.
In terms of applications, the source data points to wood, metal, paints, coatings, and composites. That broad range is what makes this disc useful in mixed-material environments such as cabinet shops, automotive refinishing, general woodworking, and repair work. Instead of chasing a specialty abrasive for every step, the Mirka Gold line is built to cover the common sanding jobs most users hit every week.
Who should buy it? Anyone running a 5-inch sanding process and looking for a quality 180-grit disc in bulk. If you burn through abrasives doing furniture prep, finish work, bodywork sanding, or shop production, the 100-count pack makes sense. If you only sand once in a while, it is still a solid option, but this pack size is especially practical for users who want to stock up and stay working.

Pro Tip
P180 is a strong middle-step grit. If you are refining wood or coatings, use it after heavier stock removal and before your finer finishing grit so you do not waste discs trying to make one grit do every step.
