Mirka 5-in 100 Grit Mesh Abrasive Dust Free Sanding Discs - Box of 50

Our review of the Mirka 5-in 100 Grit Mesh Abrasive Dust Free Sanding Discs finds them best suited for professional finishers and serious DIYers who need fast, clog-resistant sanding on wood, primer and paint. The bottom line: these discs are designed to stay effective longer because the open mesh construction reduces dust buildup and maintains aggressive cutting throughout each disc's life. In this review the standout is consistently even material removal with less loading, which speeds work and reduces time spent changing discs and clearing clogs.

Key Features

• Mesh construction: The open abrasive mesh sheds dust and debris so the disc stays cutting and requires fewer changes during long sessions.
• 100 grit abrasive: The medium-coarse grit balances material removal and surface preparation for primer, paint and light shaping tasks.
• 5-in diameter: The common 5-in size fits most random orbital sanders for wide compatibility with standard finishing tools.
• Box of 50: A bulk pack reduces runouts and downtime by providing a steady supply of replacement discs for workshop or jobsite use.
• Dust free claim: The design helps control airborne dust compared with closed-back discs, improving visibility and cleanup during sanding.

Who It's For

These discs are ideal for automotive refinishers, cabinetmakers and painters who need a reliable mid-grit abrasive that resists clogging. The 5-in size and 100 grit make the set especially useful when prepping surfaces for filler or primer where consistent cut is important.

Those who should look elsewhere include users needing very fine finishing grits for final polishing or heavy stock removal beyond what a 100 grit can handle; also buyers who require hook-and-loop attachment if their sander uses an alternate backing system not compatible with these discs.

Pros & Cons

Pros

• Open mesh helps prevent loading, so cutting performance remains steady on dusty or resinous materials.
• Box of 50 provides good value for frequent users and reduces interruptions on the job.
• 5-in size fits most common random orbital sanders for broad tool compatibility.

Cons

• Only offered in 100 grit in this pack, so additional grits must be purchased separately for a complete workflow.
