Mirka 5-Inch 800 Grit Mesh Abrasive Dust Free Sanding Discs - Box

In this review the Mirka 5-in 800 grit mesh abrasive discs are evaluated as a specialist finishing product for professionals and careful DIYers. The bottom line: these discs are best for fine sanding tasks where dust extraction and a consistent finish matter most. The reviewer found the mesh design and fine 800 grit abrasive deliver a smooth, predictable surface on primed wood and painted panels, and the box of 50 keeps a reliable supply on the bench. This review focuses on real use, intended applications, and practical limits so you can decide if they match your workflow.

Key Features

• 5-in diameter: Fits most random orbital sanders used for light finishing work and provides even coverage without oversize tooling.
• 800 grit mesh abrasive: Offers a very fine cut for smoothing between coats and preparing surfaces for polishing without aggressive material removal.
• Mesh construction: Promotes dust extraction so sanding debris is removed efficiently, helping to keep work surfaces cleaner and prolong abrasive life.
• Box of 50 discs: Supplies a workshop or jobsite with a bulk quantity of replacement discs to reduce downtime and repeated ordering.
• New condition: Delivered unused and consistent across the lot, which helps ensure repeatable finishing results from disc to disc.

Who It's For

These discs are aimed at finishers, bodyshop technicians, and woodworkers who need a fine abrasive for sanding between coats, leveling light imperfections, or preparing surfaces for final polishing. The combination of 800 grit and mesh design benefits users who employ dust extraction systems and value a cleaner working environment.

Users who need heavy material removal or a coarse grit sequence should look elsewhere; this product is not intended for aggressive stock removal or initial paint stripping. Occasional DIYers who do not have dust collection may still use them, but will not see the full advantage of the mesh dust-free design.

Pros & Cons

Pros

• Very fine 800 grit gives smooth, consistent finishes ideal for between-coat sanding.
• Mesh design aids dust extraction, reducing clogging and extending disc life when used with a vacuum.
• Box of 50 keeps a steady supply for workshop use and repetitive tasks.
• Standard 5-in size fits common finishing sanders for convenient compatibility.

Cons

• Not suitable for heavy stock removal or initial sanding stages due to the fine 800 grit.
• Full benefit requires a dust extraction system; users without vacuum setup may not see reduced dust levels.
