Compact 1.25-Inch Sanding Pad
The small 32 mm (1.25-inch) pad is designed for localized sanding rather than large-area material removal. This makes the AROS150-B particularly useful for correcting small defects without unnecessarily disturbing the surrounding surface.
It is a practical choice for spot repair work such as sanding small imperfections in clear coat or topcoat surfaces before polishing. Mirka specifically positions its cordless sanding tools for automotive spot repair and finishing applications.
Efficient 5 mm Random Orbit
The 5 mm orbit provides a balance between sanding efficiency and control. The random orbital movement helps produce a consistent sanding pattern while making the tool suitable for localized surface preparation.
This configuration works well with appropriate spot-repair abrasives when removing small surface imperfections or preparing an area for subsequent polishing.
Cordless Freedom of Movement
One of the main advantages of the AROS150-B is its cordless design. Without an electrical cable or pneumatic hose connected to the tool, the operator can move freely around the workpiece.
This is especially useful during automotive refinishing, where maintaining control around freshly finished surfaces is important. Mirka highlights the freedom from cords and pneumatic hoses as a key benefit of its cordless spot-repair tools.
Brushless Motor Performance
The AROS150-B uses a brushless motor and provides a speed range of 4,000 to 8,000 rpm. The adjustable speed allows the operator to select a suitable setting for the abrasive and the particular repair or finishing task.
Brushless motor technology also eliminates conventional carbon brushes, helping reduce routine maintenance requirements.
Designed for Spot Repair
The AROS150-B is particularly well suited to removing small imperfections from painted surfaces, clear coats, and other finished substrates. Mirka's spot-repair system is designed around small-diameter abrasives that allow defects to be treated locally rather than sanding a much larger surrounding area.
Recommended Applications
Automotive spot repair
Removing dust nibs
Clear-coat defect removal
Paint and topcoat preparation
Localized surface sanding
Denibbing
Finishing and refinishing
Small-area composite sanding
Preparation before polishing
Quality-control and finishing work
Battery & Charging Options
Mirka offers the AROS150-B in different configurations. The AROS150-B-NV is a tool-only version, while other packages can include two 2.5 Ah batteries and a charger. Mirka states that the 12 V, 2.5 Ah battery can provide up to 16 hours of industrial use and can charge in approximately 45 minutes; using two batteries allows one battery to be used while the other is charging.
Always check the exact SKU to determine whether batteries, charger, backing pads, and other accessories are included.
Ergonomic and Easy to Handle
The compact design of the AROS150-B is intended for detailed sanding where precise control is more important than large-area coverage. Its lightweight tool body and angled configuration make it easy to position over small repair areas.
With a listed tool weight of approximately 1.23 lb (0.56 kg) before adding the battery, the sander is designed to minimize unnecessary bulk during detailed work.
Non-Vacuum Design
The AROS150-B is specified as a non-vacuum sander. This makes it particularly suitable for the localized spot-repair applications for which the tool is designed.
For dust and debris management, users should follow the recommended sanding and workplace procedures appropriate for the material being worked on.
