Mirka 5 inch Finishing Sander 2.5mm Orbit MR-525

Mirka MR-525 – 5" Finishing Sander, 2.5mm Orbit

The Mirka MR-525 is a 5" random orbital finishing sander with a fine 2.5mm orbit, optimized for final finishing passes where minimizing swirl marks is the priority. Built in Finland, it shares the same precision engineering as the broader Mirka MR series. The tighter orbit produces a finer scratch pattern suitable for pre-coating, lacquering, and finishing prep on wood and composites.

Why Choose the MR-525?

• 2.5mm orbit – Fine scratch pattern minimizes swirl marks on sensitive surfaces before coating.
• 5" pad – Works with the standard 5" Mirka abrasive disc range (Abranet, Galaxy, Gold).
• Finnish precision engineering – Consistent orbit for repeatable surface results.
• Ideal for final grit sequences – Best suited to 150–400 grit finish sanding passes.
• Compact design – Manageable weight for extended finishing sessions.

Ideal Applications

• Final finishing passes before lacquer, stain, or paint application
• Automotive clear coat sanding and polishing prep
• Fine sanding on furniture and cabinet doors
• Composite and veneer surfaces requiring minimal scratch depth
