Mirka AOS-B Medium Package + AROP-B
Cordless compact set for precise paint corrections, spot fine sanding, and controlled polishing of small areas.
The set combines the Mirka AOS-B 130 for fine sanding work on very small surfaces with the Mirka AROP-B 312NV for polishing work on small areas. This creates a flexible workflow for spot repairs, detailing, and local defect corrections.
Introduction with Clear Practical Benefits
When small paint defects need to be processed cleanly and reproducibly, the combination of a compact sander and a matching polishing machine is a real advantage. This is exactly where the Mirka AOS-B Medium Package + AROP-B comes in: small backing pad diameters, cordless operation, and coordinated components help with pinpoint work, protecting adjacent surfaces and cleanly blending corrections.
For workshops, smart repair, and demanding detail work, this set is particularly interesting when mobility, precision, and controlled processing are more important than surface area performance. The speeds and procedures mentioned in this article are intentionally formulated as guidelines, as material, paint structure, polish, pad, and user pressure all influence the result.
Product Overview: Components, Uses, Advantages
| Component | Use | Key Data | Practical Advantage |
|---|---|---|---|
| Mirka AOS-B 130 | Spot fine sanding on small areas | 32 mm pad, 3 mm stroke, 4,000–8,000 rpm | Highly controllable on narrow and sensitive areas |
| Mirka AROP-B 312NV | Polishing small areas after sanding | 77 mm pad, 12 mm stroke, 4,000–7,000 rpm | Clean correction of small surfaces with good guidance |
| Polarshine 12, 250 ml | Polish for finishing and correction stages | Included in the set | Suitable for small polishing areas and controlled processing |
| 32 mm / 77 mm Accessories | Coordinated processing from defect to finish | Backing pads, pads, abrasives, battery, charger, case | One set for mobile use without long assembly time |
Recommended Base Settings as Guidelines
The following values are not rigid requirements, but practical starting points based on the technical specifications of the devices. Material, defect pattern, polish, pad, temperature, and contact pressure all affect the result.
| Work Step | Machine | Guideline Speed | Note |
|---|---|---|---|
| Fine sanding of small defect areas | AOS-B 130 | approx. 4,000–6,000 rpm | Begin in the lower to medium range for controlled material removal. |
| Blending / Refining transition | AOS-B 130 | approx. 6,000–8,000 rpm | Only work with a securely guided tool and suitable abrasive. |
| Starting polish on small surfaces | AROP-B 312NV | approx. 4,000–5,000 rpm | Distribute product cleanly and monitor temperature development. |
| Correction / Finish on small areas | AROP-B 312NV | approx. 5,500–7,000 rpm | Use only as much pressure as necessary; reduce pressure if the red LED lights up. |
Professional Workflow in 6 Steps
- Inspect and mask surface: Properly assess defect pattern, edge zones, and adjacent components. Target small areas specifically.
- Center abrasives correctly: The abrasive or pad must sit flat and clean on the backing pad so that the machine runs smoothly.
- Fine sanding with AOS-B 130: Start at moderate speed and only remove as much material as necessary. Let small transitions fade out in a controlled manner.
- Clean and inspect surface: Check the scratch pattern, remove residues, and only then start the polishing stage.
- Polishing with AROP-B 312NV: Use Polarshine 12 sparingly, distribute on a small area, and build up the correction systematically.
- Finish and final check: Buff the surface, check temperature and gloss appearance, remove the battery, and clean the tool for the next use.
Typical Error Patterns and Corrective Measures
1. Machine reduces speed
- Reduce pressure temporarily.
- Keep an eye on tool temperature and give the machine a moment to breathe.
- Do not work with unnecessarily high contact pressure on small surfaces.
2. Right LED lights up red
- Reduce load and make the working style softer.
- Do not permanently "hold onto" the machine; guide it instead.
- Plan short cooling phases during prolonged heavy use.
3. Left LED red, machine does not run
- Check battery voltage and charge battery.
- Insert battery correctly.
- If battery behavior is unusual, check battery health and replace if necessary.
4. Scoring or gouges in the finish
- Always place the tool on the surface before starting.
- Allow the polishing or sanding process to stop completely before lifting off.
- Coordinate pad, polish, and speed for the small processing zone.
Maintenance at a Glance
- Remove the battery before any maintenance work.
- Remove dust deposits with a soft brush.
- Clean the machine body only with a soft, slightly damp cloth.
- Do not use aggressive cleaners such as alcohol, gasoline, lye, or corrosive agents.
- Service and repairs must only be performed by authorized Mirka service centers.
FAQ
What is this set particularly suitable for?
For local paint corrections, spot fine sanding, and subsequent polishing of small areas where compact pad diameters and cordless operation offer advantages.
Which machine handles which step?
The AOS-B 130 is designed for fine sanding of small defect zones, while the AROP-B 312NV is for polishing small areas with a 77 mm pad.
How long do the batteries take to charge?
As a guideline, the BCA 108 charges a 2.5 Ah battery in under 50 minutes and a 5.0 Ah battery in under 100 minutes. Ambient temperature and battery condition can extend charging time.
What to do if the machine slows down under load?
Usually, reducing the pressure and giving the tool a short moment helps. Especially on small surfaces, too much pressure leads quickly to heat and a drop in speed.
How should I store the battery and charger properly?
Best in a cool place, not in a fully discharged state, and not outside the recommended charging and temperature ranges. During long breaks, the battery should be recharged regularly.
