Additional Information
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 Roundy Hand Sanding Block Kit

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!
I received my mixed box of 125mm Mirka Galaxy discs from Best Abrasives a little while ago...that stuff is amazing!
I let the 80 grit go on a piece of rough sawn Camphor Laurel and it was smooth in a couple of minutes. Very impressive compared to other brands...I'll be back for more! 🙂

Good product makes work a lot easier with the extended hose
Best Abrasives deliver on time every time and have a huge range of Mirka products that aren’t available elsewhere. Competitive pricing and realistic freight charges to rural areas. Don’t think about ordering from Best Abrasives just go ahead and do it, you wont be disappointed.
I am a painter and bought this after lots of research. I have not regretted the purchase and sanding or removing paint has become much quicker and easier. Using Abranet, galaxy or iridium sanding discs make light work of any job. I will definitely buy more Mirka products, Great quality
