Key Features
Overview
The Mirka AE23205025 Autonet 240 Mesh Grip Sanding Discs are 5-inch extra-fine sanding discs built for surface refinement and clean dust extraction. This is a mesh sanding disc designed for automotive refinishing and fine surface prep. Model AE23205025 comes packed with 50 discs per box, giving body shops, paint prep crews, and serious finish-focused users a consistent supply for repeat work.
What matters here is not just the 240 grit rating, but how the disc is built. Mirka uses aluminum oxide abrasive on a dense polyamide mesh structure instead of a more traditional paper-style disc face. In real use, that means the abrasive can keep cutting while dust is pulled away more effectively, which helps reduce loading and keeps the surface more uniform as you work through primers, fillers, and finish prep steps.
The Autonet line was specifically developed for the demands of automotive refinishing, and that tells you where this product really makes sense. If you are working on panels, blending areas, or getting a surface ready for the next stage, a finer 240 grit disc gives you control without leaving the kind of rough scratch pattern you would expect from a more aggressive abrasive. That makes it a better choice when the goal is surface quality rather than fast material removal.
The 5-inch format is a common size for sanders in this class, which makes these discs practical for everyday shop use. The mesh construction also supports better airflow during sanding, and that directly affects cleanup, visibility, and finish quality. Less built-up dust on the disc usually means fewer interruptions, less chance of debris tracking across the workpiece, and a more predictable result from disc to disc.
If you are comparing sanding discs, the real difference with this one is efficiency in dusty refinishing work. Plenty of discs can sand. Fewer keep the surface cleaner while doing it. That is why mesh abrasives have become popular in finish work where rework costs time and money. When a sanding disc can help speed up the process and improve the surface at the same time, it earns its place in the shop.
Who should buy it? Anyone doing automotive refinishing, paint prep, or detail-focused finish sanding with a 5-inch sander setup. It also makes sense for users who are tired of conventional discs clogging too quickly in finer grit work. If your priority is a cleaner cut, better dust extraction, and a more refined finish step, this Mirka sanding disc is aimed right at that job.
Cleaner Sanding in Dusty Work
When you are sanding fine surfaces, dust control is not just about cleanup. It affects how evenly the disc cuts and how clean the finish looks before the next step.
- Mesh construction is designed to support strong dust extraction
- Built for automotive refinishing where surface quality matters
Fine Grit for Surface Prep
A 240 grit disc sits in the range where control starts to matter more than aggression. It is a good choice for refining a surface before coatings, paint stages, or other finish work.
- 240 grit extra-fine abrasive helps leave a more refined scratch pattern
- Aluminum oxide abrasive balances cutting action and consistency
Stock Up for Repeat Jobs
A box of 50 makes sense for anyone burning through discs in regular prep work. You get consistent grit, consistent size, and enough quantity to keep the bench supplied.
- Includes 50 sanding discs per box
- 5-inch disc size fits common sanding setups in this category

Pro Tip
If you are buying mesh discs for fine work, run them with dust extraction whenever possible. That is where this style of abrasive really pays off, because keeping the disc clear helps the 240 grit cut more evenly and keeps the finish cleaner.
