The Mirka Mirka AROS-B 150NV 32mm 10.8V 2.5Ah Orbit 5.0 AN is a brushless spot repair sander with a 5 mm orbit, small, ergonomic and energy efficient. There is no cord to get tangled in and no air supply that can get contaminated; this tool does not even require oiling. The 10.8V Li-ion battery lasts up to 16 hours in industrial use and charges in 45 minutes. 

As with all Mirka machines, the ergonomic design has been a priority to ensure that the light tool can comfortably be used for long periods without fatigue. These strong cordless sanders enable a long working time as the battery lasts up to 16 hours in spot repair sanding operations. The lithium-ion battery charges in only 45 minutes. 
Full Description

Battery Tips

The battery pack is not fully charged when delivered, charge the batteries before you use it. To get the longest possible battery life we recommend:

Never store the battery in a discharged condition, recharge it immediately after it has been discharged.
If you store your tool for long periods of time without use, recharge the battery every month. This will prolong the battery life.

When the trigger is released the sander will stop but continue to stay in active mode for a short time before it automatically deactivates/turns off.

When the sander is in active mode the LED light to the right is green.

In active mode, the LED light to the left shows the battery status
Green: Battery charge level is 75-100%.
Flashing green: Battery charge level is 50-75%.
Flashing green/red: Battery charge level is 25-50%.
Red: Battery voltage too low, tool is not operable.

Mirka AROS-B is a sensational sander that will save untold time and effort!

I spend hours on manually sanding the curves in the depressions I route in my charcuterie boards as there's just no other way to do it, using the AROS-B sander I can now do a full board in around 20 minutes and then have it ready to oil! I estimate it's saving me at least 3-4 hours per board.

Expensive tool but it reall works fantastic with a lot of grunt, and saves an incredible amount of time and effort! I love it so much a week later I bought the AOS-B as well!

Couldn't recommend this unique sander highly enough for fiddly awkward sanding jobs!

Amazing little workhorse!

I bought the cordless Mirka Aros-B 32mm Orbit sander to speed up the process of finishing wood projects that have either difficult areas to reach or have small components. It’s been absolutely perfect for both as it’s compact, light weight and powerful. I love it.
