Mirka 3 inch Random Orbit Cordless Polisher with 12mm Orbit AROP312-B

Mirka AROP312-B – 3" Random Orbit Cordless Polisher, 12mm Orbit, 10.8V

The Mirka AROP312-B is a 3" random orbit (dual-action) cordless polisher with a 12mm orbit, running on Mirka’s 10.8V battery platform. The 12mm orbit provides aggressive polishing action for paint correction, compound work, and defect removal, while the random orbital motion reduces the risk of swirl marks compared to a pure rotary drive. It is compact enough to work in tight areas while delivering meaningful polishing force on curved and contoured painted surfaces.

Why Choose the AROP312-B?

• 12mm orbit – Aggressive random orbital action for efficient paint compounding and defect removal.
• Random orbital (DA) motion – Reduces swirl risk versus rotary polishers on delicate paint finishes.
• 3" compact pad – Reaches panel contours and tight areas larger polishers cannot access.
• 10.8V cordless – No cord restriction during bodywork or panel polishing in awkward positions.
• Finnish Mirka engineering – Professional-grade construction and orbit precision.

Ideal Applications

• Automotive paint correction and compounding on curved panels
• Defect removal and swirl reduction on clear-coated surfaces
• Detail polishing on small panels and contoured surfaces
• Final polishing passes on lacquered furniture and coated surfaces
